Start the qualifier

If you are looking for a Denver RTD bus accident lawyer, start with the deadline, not the slogan. An RTD bus crash is a public-transit injury claim with a different evidence map, a different defendant structure, and a notice clock that can punish waiting. If the bus was owned or operated by the Regional Transportation District or another public entity, Colorado's Governmental Immunity Act requires a written notice of claim within 182 days after discovery of the injury. C.R.S. § 24-10-109(1) calls that filing a jurisdictional prerequisite. In practice, lawyers often calendar it as a 180-day emergency deadline because a one-day calendar mistake is unforgiving. That notice is separate from calling police, reporting the crash to RTD, talking to an adjuster, or getting a claim number.

This matters because many RTD crashes do not look catastrophic on day one. A passenger may be thrown forward after a hard stop and develop neck, back, shoulder, or concussion symptoms over the next week. A pedestrian or cyclist may need surgery, rehab, or months of specialist care before anyone knows the full medical picture. The government-notice clock can run while that picture is still forming. Our Denver bus accident lawyer page is the practice-area home for transit-injury claims. This guide stays on the RTD notice problem, who to serve, and the evidence that makes an RTD bus claim real. The statute teardown lives in our RTD 182-day notice guide.

Video: the RTD 182-day notice

This existing Conduit Law video walks through Colorado's written notice of claim when a public entity is involved. An RTD bus, light-rail car, or other government vehicle can put that 182-day clock in play long before the ordinary injury deadline.

Watch the companion at conduit.law/videos/colorado-notice-of-claim-government-entity. The written-notice teardown is in our RTD 182-day notice guide. General information only, not legal advice.

Why RTD Bus Claims Are Procedurally Different

RTD is not a private rideshare company, charter operator, or hotel shuttle vendor. It is a regional public transit agency. That public-entity status can change how the claim is presented, what defenses get raised, which records are available through public-records channels, and when a formal notice must be served. The same injury that would be handled as a normal commercial vehicle claim against a private shuttle company may become a CGIA notice case when the vehicle is an RTD bus or another government-operated transit vehicle.

The trap is that injured people often think they have already given notice because they spoke with a driver, filled out an incident card, called law enforcement, contacted customer service, or received a call from a claims representative. Those steps may help prove the event happened. They are not the same as a legally sufficient governmental notice of claim. A CGIA notice must contain specific information and must be sent to the correct public entity or public employee representative. If it is late, the defense may argue the claim is barred before liability and damages are ever reached.

CGIA Notice and the 182-Day Deadline

The statute is the Colorado Governmental Immunity Act, usually shortened to CGIA. In conversation, clients and even lawyers sometimes say "GIA notice" or "governmental immunity notice." The abbreviation is not the point. The point is that a public-entity bus case has a short written-notice requirement that is much stricter than the ordinary motor-vehicle statute of limitations.

  • Private vehicle crash: Colorado motor-vehicle injury claims generally have a three-year filing deadline under C.R.S. § 13-80-101.
  • Public bus or government vehicle: a written CGIA notice is due within 182 days after discovery of the injury under C.R.S. § 24-10-109(1). Safe practitioners often calendar it as a 180-day deadline.
  • Notice is not a lawsuit: the notice is a precondition. It does not replace later litigation deadlines, and it does not authorize an immediate complaint.
  • Notice must go to the right place: telling the driver, police, customer service, or a generic insurer may not satisfy the statute.

That is why RTD cases should be reviewed quickly. The medical case may need months to mature. The notice analysis needs to happen immediately. For the contents list, addressee, service method, and what a late notice costs, use the 182-day government claim notice guide. This page keeps the RTD facts; that page owns the statute.

What the 182-Day RTD Notice Must Contain

C.R.S. § 24-10-109(2) is a checklist, not a suggestion. The notice shall contain five items:

  1. the name and address of the claimant and of the attorney, if any;
  2. a concise statement of the factual basis of the claim, including the date, time, place, and circumstances of the act, omission, or event;
  3. the name and address of any public employee involved, if known;
  4. a concise statement of the nature and the extent of the injury claimed to have been suffered; and
  5. a statement of the amount of monetary damages that is being requested.

If a field is unknown, say so in the notice rather than guessing a name or a number you cannot support. Colorado courts have been more flexible about the completeness of those contents than about the 182-day deadline itself. A thin letter that still identifies the event and the injury may survive a contents challenge. A perfect letter mailed on day 183 does not. Date, time, place, bus number, route, and a plain description of what happened are the parts that let the entity pull video before it overwrites.

Hypothetical only, not a Conduit result: a passenger thrown by a hard stop on Colfax who waits to "finish physical therapy" before sending notice can lose the public-entity claim even when the video would have shown the stop. There is no settlement figure attached to that example.

Who to Serve for an RTD Claim

A notice sent to the wrong desk can be as fatal as a notice sent late. C.R.S. § 24-10-109(3)(a) splits the addressee by defendant. If the claim is against the state or a state employee, the notice shall be filed with the Attorney General. RTD is a regional public transit agency, not the State of Colorado, so an RTD injury notice generally goes to the governing body of the public entity or the attorney representing the public entity. The same subsection says the notice is effective upon mailing by registered or certified mail, return receipt requested, or upon personal service. Ordinary first-class mail, an email to a generic inbox, or a message left with a driver is not the statutory method. C.R.S. § 24-10-109(3)(b) adds a safe harbor: a notice properly filed with a public entity's agent listed in the inventory of local governmental entities under C.R.S. § 24-32-116 is deemed to satisfy the section.

Identifying the correct entity is part of the notice job, not a later discovery problem. The 2026 Colorado Supreme Court decision in Mostellar v. City of Colorado Springs held that the 182-day period runs from discovery of the injury, not from later learning which public entity was responsible. If more than one public entity may be involved — a city street, a county road, a state highway, a transit district — calendar a notice to each plausible entity inside the 182-day window. Keep the certified-mail receipt, the return card, and a complete copy of what was sent.

RTD Light Rail vs. RTD Bus

The vehicle is different. The notice problem is often the same. C.R.S. § 24-10-103(2.7) defines motor vehicle to include a motor vehicle under C.R.S. § 42-1-102 and a light-rail car or engine owned or leased by a public entity. That is why an RTD bus injury and an RTD light-rail injury can both be CGIA notice cases. This page stays on the bus file: bus number, route, hard-braking and telematics data, onboard and stop cameras, boarding and wheelchair-securement issues. A light-rail file still needs the 182-day notice, but the evidence map shifts toward platform cameras, train-control data, and station conditions. Until a dedicated light-rail guide is published, the notice rules on this page and on the government-claim notice guide still apply.

Who May Be Responsible in an RTD Bus Accident?

RTD may be the obvious name on the side of the bus, but the liability analysis should not stop there. Serious transit cases often involve a stack of operators, contractors, maintenance vendors, other drivers, and road-design issues. Sorting those layers early helps identify every deadline and every insurance or self-insurance source.

  • RTD/operator conduct: speeding, following too closely, unsafe turns, hard braking, distracted operation, unsafe boarding, or failure to yield.
  • Route and dispatch issues: unrealistic schedules, unsafe stop placement, crowding, weather routing, or poor response to known hazards.
  • Maintenance contractors: brake, tire, steering, door, wheelchair securement, camera, or inspection failures.
  • Other drivers: a private motorist may cut off a bus, run a red light, or cause a collision that injures passengers inside the bus.
  • Road or stop conditions: dangerous intersections, construction zones, inadequate crosswalks, snow/ice, lighting, or signage issues.
  • Vehicle equipment failures: doors that do not cycle correctly, seats or securement hardware that fail in ordinary use, or safety features that were out of service — treated here as maintenance and operator issues, not as a product-liability claim.

A good RTD claim does not assume the public entity is the only target. It asks who controlled the risk and who had records showing the risk could have been prevented. After a timely notice, C.R.S. § 24-10-109(6) still bars filing the lawsuit until the entity denies the claim or 90 days pass, whichever occurs first. Judgment amounts against public entities are separately limited by C.R.S. § 24-10-114. Those are statutory caps, not case results.

Evidence to Preserve Before It Disappears

Transit cases are evidence-sensitive. The best proof is often controlled by the agency, the bus system, a contractor, or nearby businesses. Video may overwrite quickly. Passenger names may never make it into a police report. The vehicle number, route, and exact time may be the difference between getting the right footage and getting nothing. Early preservation work is not paperwork theater; it can decide the case.

  • Bus number, route number, stop location, direction of travel, date, and exact time
  • Onboard video, exterior cameras, dash cameras, bus-stop/platform video, and nearby business cameras
  • Operator identity, training records, prior complaints, route assignment, dispatch communications, and incident reports
  • Hard-braking, GPS, speed, telematics, event-recorder, and schedule-adherence data
  • Maintenance records, inspection sheets, defect reports, brake/tire/door records, and contractor work orders
  • 911 audio, police reports, bodycam footage, witness statements, passenger contact information, and photographs
  • Medical records tying the crash to concussion symptoms, spine injuries, fractures, shoulder/knee injuries, or psychological trauma

For passengers, the missing-witness problem is common. People get off the bus, leave the scene, and disappear. If you can safely collect names, numbers, photos of the bus, and screenshots of route information, do it. If not, counsel should move quickly to request and preserve the agency records.

Common RTD Bus Accident Scenarios

RTD cases come in several shapes, and each one needs a different proof strategy.

  • Passenger thrown by sudden stop: the case may turn on video, speed, following distance, operator explanation, whether another vehicle created a true emergency, and whether the passenger had a reasonable opportunity to sit or hold a rail.
  • Bus collision with another vehicle: the claim may involve both RTD and the other driver, with coverage and fault split between public-entity rules and private auto insurance.
  • Pedestrian or cyclist struck by bus: blind spots, right turns, bus-stop design, crosswalk timing, and operator scanning become central. These cases may also connect to our Denver pedestrian accident and Denver bicycle accident resources.
  • Boarding/exiting injury: doors, curbs, mobility devices, ramps, kneeling-bus features, passenger assistance, and stop conditions may matter.
  • Catastrophic injury or death: brain injury, spinal injury, surgery, permanent impairment, or a fatal crash requires early expert involvement and careful damages development.

How RTD Cases Differ From Private Shuttle and Charter Bus Cases

The government/private distinction is the non-commodity part of bus accident work. A privately owned shuttle, charter bus, tour bus, church bus, employer van, hotel shuttle, airport shuttle, medical transport vehicle, or ski shuttle usually does not create the same CGIA notice issue. Instead, the case may involve commercial insurance policies, driver qualification files, federal motor carrier rules, maintenance logs, dispatch records, and corporate safety practices.

The gray area is where cases get dangerous. A school district may use a private contractor. A public facility may rely on a private shuttle. A private maintenance company may service a public vehicle. A crash may involve an RTD bus and a negligent private driver. A transit platform injury may involve public property plus a private construction contractor. These mixed-operator cases require both government-notice analysis and commercial evidence preservation. Treating them as ordinary car crashes can miss the deadline, the contractor, or the policy that matters.

Medical Proof and Case Value

Bus passengers often lack seatbelts, airbags, and warning before impact. A hard stop can throw someone into a pole, farebox, stairwell, seat frame, door, floor, or another passenger. Pedestrians and cyclists face the added danger of a large vehicle with long stopping distance and significant blind spots. Case value depends less on the word "bus" and more on the injury proof, liability proof, and available recovery sources. Nothing here is a predicted settlement range.

  • Brain injuries: concussion, dizziness, headache, visual symptoms, cognitive fatigue, memory problems, and post-concussion syndrome.
  • Spine injuries: disc herniation, radiculopathy, fractures, injections, surgery, or spinal cord involvement. See our Denver spinal injury page for serious cases.
  • Orthopedic injuries: shoulder tears, wrist fractures, hip/knee injuries, ankle trauma, and surgery.
  • Psychological harm: transit anxiety, sleep disruption, panic symptoms, and PTSD-type symptoms after violent crashes.
  • Economic harm: missed work, reduced earning capacity, care needs, transportation costs, and future medical treatment.

The medical timeline should be built alongside the notice and evidence timeline. Waiting for treatment to finish before preserving bus evidence is a mistake.

School Buses, Children, and Recorded Statements

The 182-day notice rule is not limited to RTD. A school bus run by a public school district, or a shuttle operated by a city, county, or state agency, is usually a public-entity vehicle, so the same written notice requirement (C.R.S. § 24-10-109) may apply. When a district or agency hires a private company to run the route, that company may not be a public entity at all, and the claim may instead follow the ordinary 3-year motor vehicle deadline (C.R.S. § 13-80-101(1)(n)). Sometimes both apply to different defendants. When the injured passenger is a child, confirm the deadline right away rather than assuming the child's age changes it, and plan for a longer medical horizon, since a child's recovery can take years to understand.

After a bus crash, the operator's claims department may ask for a recorded statement. It can sound routine, but questions like "Were you holding the rail?" or "Have you had back problems before?" can later be used to argue that you share some of the fault. Under Colorado's modified comparative negligence rule (C.R.S. § 13-21-111), your recovery is reduced by your share of fault, and at 50% you recover nothing. You can ask to keep communication in writing until you have talked with a lawyer and your medical picture is clearer.

What To Do After an RTD Bus Accident

  1. Get medical care. Head, neck, back, shoulder, and knee injuries often worsen after the adrenaline drops.
  2. Save transit details. Route, bus number, stop, direction, time, driver description, ticket/app receipt, and photos matter.
  3. Document witnesses. Other passengers may be the only neutral proof of a hard stop or unsafe maneuver.
  4. Do not rely on a generic report. Reporting the incident is not the same as serving a CGIA notice. See how the written notice works.
  5. Calendar the government-notice deadline immediately. Treat the 182-day window as urgent; many lawyers mark 180 days so a weekend does not blow the statute.
  6. Preserve video and records. Request onboard video, dispatch data, maintenance records, and witness information before routine deletion.
  7. Talk to counsel before signing releases. Public-entity and mixed-operator cases can be undervalued early.

Frequently asked questions

Can I sue RTD after a Denver bus accident?

Often the first step is not a lawsuit. RTD is a public entity. C.R.S. § 24-10-109(1) generally requires a written notice of claim within 182 days after discovery of the injury. Compliance is a jurisdictional prerequisite. After a timely notice, § 24-10-109(6) still bars filing suit until the entity denies the claim or 90 days pass, whichever comes first. The lawsuit itself must still be filed within the ordinary Title 13 deadline — generally three years for a motor-vehicle injury under C.R.S. § 13-80-101. Whether RTD, a contractor, or another driver belongs in the case depends on the facts. This is general information, not a prediction that any particular claim will succeed.

How do I give the 182-day CGIA notice after an RTD crash?

Calendar 182 days from discovery of the injury under C.R.S. § 24-10-109(1). Practitioners often treat it as a 180-day emergency deadline so a calendar mistake does not blow the statute. The notice must be written and must include the five items in § 24-10-109(2). Serve it on RTD's governing body or the attorney representing the public entity, by registered or certified mail, return receipt requested, or by personal service (§ 24-10-109(3)(a)). A notice properly filed with the entity's agent listed under § 24-32-116 also satisfies the statute. A police report, incident card, customer-service ticket, or call to a claims representative is not the statutory notice. The full teardown is in the Colorado notice of claim guide.

What must be in a Colorado notice of claim against RTD?

C.R.S. § 24-10-109(2) requires five items: the claimant's name and address and the attorney's name and address if any; a concise factual statement including date, time, place, and circumstances; the name and address of any public employee involved, if known; a concise statement of the nature and extent of the injury; and a statement of the monetary damages requested. If a field is unknown, say so rather than guessing. Courts have been more flexible about contents completeness than about the 182-day deadline itself.

Who do I serve with an RTD notice of claim?

RTD is not the State of Colorado, so the notice generally does not go to the Attorney General. C.R.S. § 24-10-109(3)(a) says a claim against a non-state public entity or its employee is filed with the governing body of the public entity or the attorney representing the public entity. The notice is effective on registered or certified mail, return receipt requested, or on personal service. A notice properly filed with the entity's agent listed under C.R.S. § 24-32-116 also satisfies the statute. Identifying the correct entity is part of the notice job. If more than one public entity may be involved, calendar a notice to each plausible entity inside the 182-day window.

Is an RTD light-rail crash different from an RTD bus crash?

The vehicle is different. The notice problem is often the same. C.R.S. § 24-10-103(2.7) defines motor vehicle to include a motor vehicle under C.R.S. § 42-1-102 and a light-rail car or engine owned or leased by a public entity. That is why an RTD bus or light-rail injury can be a CGIA notice case. Evidence still differs: rail video, platform cameras, and train-control data instead of a bus number and hard-braking log. This page is the bus and RTD-claims guide.

Does reporting the crash to RTD or police count as CGIA notice?

No. C.R.S. § 24-10-109 requires a written notice with specific contents, served on the correct public-entity addressee. An incident report, 911 call, customer-service ticket, or conversation with a driver or adjuster may help prove the event happened. It is not the statutory notice.

How long do I have after the notice to file a lawsuit?

After a timely notice, C.R.S. § 24-10-109(6) still bars filing the lawsuit until the entity denies the claim or 90 days pass, whichever comes first. The lawsuit itself must still be filed within the ordinary Title 13 deadline — generally three years for a motor-vehicle injury under C.R.S. § 13-80-101. The notice clock and the lawsuit clock are different statutes.
