Under Colorado Revised Statutes § 42-4-1606, any law-enforcement officer who investigates, or is notified of, a traffic accident that leads to injury, serious bodily injury, death, or property damage must file a report on the state-approved form with the Department of Revenue within five days of getting the scoop or wrapping up their investigation. If they reasonably believe the damage to any one person’s property is under $1,000 and no one was hurt or killed, they don’t have to file, unless someone involved specifically asks them to, or someone can’t show proof of insurance.
