Negligence: the four elements you must prove
To recover in a Colorado rear-end case, you establish that the driver behind you (1) owed you a duty of care as a fellow road user, (2) breached that duty by following too closely, driving distracted, or failing to stop in time, (3) caused the collision through that breach, and (4) caused you measurable harm as a result. In a classic rear-end scenario, elements one through three are usually clear. The fight is almost always over the nature and extent of damages.
Three-year filing deadline: C.R.S. 13-80-101(1)(n)
Colorado gives you three years from the date of the crash to file a lawsuit for injuries arising out of the use or operation of a motor vehicle (C.R.S. 13-80-101(1)(n)). This is not a soft guideline. Missing the deadline permanently bars your lawsuit. Two important exceptions: if the at-fault driver was a government employee operating a government vehicle, a written notice of claim must be filed within 182 days of discovering the injury under the Colorado Governmental Immunity Act (C.R.S. 24-10-109(1)) and if the at-fault driver carried no insurance, your UM/UIM claim against your own insurer has its own separate deadline under C.R.S. 13-80-107.5. Do not assume three years covers every angle of your case.
Modified comparative fault: C.R.S. 13-21-111
Colorado's modified comparative fault rule under C.R.S. 13-21-111 means you can still recover damages even if you were partly at fault, as long as your share of the fault is less than 50 percent. Your award is reduced in proportion to your fault. If you are found 50 percent or more at fault, you recover nothing. Insurance adjusters routinely inflate the injured driver's fault percentage to shrink or eliminate payouts. An attorney challenges those inflated numbers with crash reconstruction evidence, dash-cam footage, and witness accounts.
Punitive damages: C.R.S. 13-21-102
Punitive damages are available in Colorado when a defendant acted with fraud, malice, or willful and wanton disregard for others (C.R.S. 13-21-102(1)(a)). In rear-end cases involving a driver who was texting, street racing, or severely impaired, punitive damages are a live issue worth evaluating. Under C.R.S. 13-21-102(1)(a), punitive damages may not exceed the amount of actual damages awarded. A court may increase that award up to three times the actual damages when a defendant continues willful and wanton conduct during the litigation (C.R.S. 13-21-102(3)).
