Colorado bicycle accident cases get a 3 years (motor vehicle); 2 years general PI statute of limitations. Helmet rule: No state law.
Published May 6, 2026
## Bicycle accident claims in Colorado
Cyclists hit by motor vehicles face severe injuries — head trauma, broken bones, road rash, internal injuries — even at low speeds. Colorado's laws balance cyclist rights and responsibilities, but the practical outcome often favors drivers in disputed fault cases.
### Colorado bicycle laws
- **Helmet law:** No state law
- **Statute of limitations on injury claims:** 3 years (motor vehicle); 2 years general PI
## Common causes of bicycle crashes
- **"Right hook"** — driver turning right cuts off cyclist going straight
- **"Left cross"** — driver turning left across cyclist's path
- **Dooring** — parked car opens door into cyclist's path
- **Distracted driving** — phone use, eating, fiddling with controls
- **Drunk / impaired driving**
- **Failure to yield** at stop signs and intersections
- **Following too closely / unsafe pass**
- **Road hazards** — potholes, gravel, drainage grates, road debris (often a government-claim case)
- **Inadequate or missing bike infrastructure**
- **Hit-and-run** — particularly common
## Cyclist's right to the road
In every state, bicycles are vehicles with the same rights and responsibilities as cars on most roadways:
- **Right to use full lane** when conditions warrant — no obligation to ride to the right edge if doing so would be unsafe
- **Same right of way** as cars at intersections
- **Same traffic-signal compliance** required (with exceptions in Idaho-stop states)
- **Hand signals** required for turns
- **Light requirements** — front white light + rear red light/reflector at night in most states
## The 3-foot rule
30+ states have laws requiring drivers to give cyclists 3 feet (some states 4 feet) of space when passing. Violation supports both:
- **Negligence per se** — automatic finding of negligence
- **Punitive damages** — for repeat or egregious violators
## Idaho-stop and similar laws
States that allow some form of yield-rather-than-stop for cyclists at signs/lights:
- **Idaho** (1982 — original)
- **Delaware** (2017)
- **Arkansas** (2019)
- **Oregon** (2019)
- **Washington** (2020)
- **Utah** (2021)
- Several others have proposed but not enacted
Where Idaho-stop applies, cyclist treatment of a stop sign as yield is NOT comparative negligence.
## Helmet defenses
If you weren't wearing a helmet (and weren't required to), defense will try to argue your head injuries should be reduced. Most states bar this argument entirely or limit it to damages-mitigation. Some states allow comparative-fault reduction.
## Common defenses against cyclists
- **"You came out of nowhere"** — driver claims surprise (often defeated by visibility analysis)
- **"You weren't using lights/reflectors"** — equipment violations support comparative fault
- **"You ran the stop sign / red light"** — supports comparative fault (or bars recovery in Idaho-stop states only when not yielding properly)
- **"You were riding against traffic"** — wrong-way riding is illegal nearly everywhere
- **"You weren't in the bike lane"** — bike-lane usage requirements vary; usually mandatory only when one exists
## Damages
Bicycle injuries typically include:
- **Traumatic brain injury** — even with helmet
- **Spinal cord injuries**
- **Multiple fractures** — clavicle, wrist, hip particularly common
- **Road rash** — significant skin injuries needing reconstruction
- **Internal injuries**
- **Dental injuries**
- **Damaged bike** — bicycles can cost $2,000-$15,000+
- **Damaged gear** — helmet, cycling shoes, jerseys, GPS
## Insurance considerations
- **Driver's auto liability** — primary source
- **Cyclist's UM/UIM** — applies in most states even when not in a vehicle
- **Cyclist's PIP / Med-pay** — pays medical regardless of fault in no-fault states
- **Homeowner's insurance** — may cover bike theft / damage as personal property
- **Health insurance** — pays medical with subrogation rights
## Evidence to preserve
- The bike itself (don't repair until evaluated)
- Helmet and gear
- Crash scene photos
- Damage photos of vehicle
- Witness names / contacts
- Police report
- Medical records
- Strava / GPS / cycle-computer data — speed, route, time
- Surveillance footage
- Driver's cell records (via subpoena)
## What you should do
If you've been hit on a bike in Colorado: get medical attention immediately, photograph everything, do NOT communicate with the at-fault driver's insurance, and contact a bicycle-accident attorney as soon as possible. Many Colorado personal-injury attorneys handle bike cases specifically — that experience matters when fighting bias against cyclists. Most offer free consultations and work on contingency.
