Wyoming Speed Limits and Penalties Update

Last scannedOct 18, 2026, 2:19 AM

In one sentence

This law allows the state transportation department to set higher speed limits on certain highways, updates fines for speeding violations, and requires a study on raising limits on non-interstate roads.

What it does

  • Allows the state transportation department to designate an 80 mph speed limit on specific interstate highways.
  • Allows the state transportation department to designate a speed limit up to 70 mph on specific non-interstate highways.
  • Updates fines for drivers who go over the speed limit on these higher-speed roads.
  • Requires the state transportation department to conduct an engineering screening study to determine if 70 mph limits are feasible on non-interstate highways.
  • Requires a report to the Joint Transportation, Highway and Military Affairs Interim Committee by November 15, 2015, regarding the study results.

Who it affects

  • Drivers on interstate highways in Wyoming.
  • Drivers on non-interstate state highways in Wyoming.
  • The Wyoming Department of Transportation.
  • The Joint Transportation, Highway and Military Affairs Interim Committee.

Limits and unknowns

  • The law does not list which specific roads will get the higher speed limits; the department must decide based on engineering and traffic investigations.
  • The study on non-interstate highways is to determine feasibility and provide a prioritized list, but it does not automatically change the speed limit.
