What trips people up most is that "aggressive driving" is often a behavior label, not a single offense with one uniform legal definition. Broadly, it means operating a vehicle in a hostile, unsafe, or impatient way that combines one or more traffic violations - such as speeding, tailgating, unsafe lane changes, failure to yield, brake-checking, or running traffic controls - in a manner that increases crash risk.

Whether it appears as a specific charge depends on the state. In Wyoming, there is no standalone statute titled aggressive driving in the main traffic code; the conduct is usually charged under specific offenses such as reckless driving under Wyo. Stat. § 31-5-229 or other moving violations. That distinction matters because the ticket, insurance consequences, and proof required will follow the actual cited offense, not the general label an officer, witness, or insurer uses.

For an injury claim, aggressive driving can be strong evidence of negligence and, in severe cases, support an argument that the driver acted with conscious disregard for safety. On commuter corridors such as I-80 between Cheyenne and Laramie, that can shape fault findings after high-speed lane-change or following-too-closely crashes.

In Wyoming civil cases, fault is evaluated under the comparative fault rule, Wyo. Stat. § 1-1-109. If aggressive driving caused the wreck, that evidence can reduce attempts to shift blame to the injured person.
