Crash Trends

As the only statewide traffic enforcement agency, the Colorado State Patrol investigates approximately 30 percent of traffic crashes in Colorado, including about 70 percent of all traffic crashes involving fatalities.

Targeting Specific Driving Behaviors

In CY 2014, troopers responded to a total of 3,712 fatal and injury crashes on Colorado highways.  The majority of these crashes (70.1 percent) were a result of:  inattentive driving, the driver exceeding safe/legal speed, driving under the influence of alcohol or drugs, lane violations, or the failure to yield the right of way.


Each crash investigated by the Colorado State Patrol is assigned a causal factor; the error which caused the crash to occur.

Inattentiveness to driving (a category that includes many behaviors, such as talking on cell phones or eating while driving) also contributes heavily to fatal and injury accidents.

Speeding is frequently a factor in fatal and injury crashes; exceeding safe or lawful speed (when considered together) are the second most common cause of fatal and injury accidents.

Aggressive driving behaviors such as lane violations also result in significant numbers of fatal and injury crashes. Other aggressive driving behaviors include following too closely, failure to yield right of way, improper passing, disregarding stop signs, and driving on the wrong side of the road.
