If you get a stop sign or red light ticket in Wyoming, you'll likely be looking at having to pay a fine. (You might have other options for dealing with a traffic citation.) This article gives an overview of what the law requires and some of the consequences of a stop sign or red light violation.
Motorists approaching a stop sign or a signal exhibiting a red light (solid or flashing) generally must come to a complete stop before the nearest of entering the crosswalk, reaching a limit line, or entering the intersection itself. (Wyo. Stat. Ann. § 31-5-222 (2024); Wyo. Stat. Ann. § 31-5-403 (2024).)
As long as there's no sign specifically restricting it, Wyoming law permits drivers to make a right turn after stopping at a red light. However, drivers need to use caution and follow the normal right-of-way rules when making the turn.
Some states don't allow left turns on red, regardless of the circumstances. However, in Wyoming, drivers can turn left after stopping at a red light at the intersection of two one-way streets. In other words, a motorist can make a left on red from a one-way street onto another one-way street.
Some states require motorists to stop at a yellow light except when it's unsafe to do so. However, in Wyoming, a yellow light is just a warning that the signal is about to turn red. In other words, you can enter an intersection on yellow, just not after the light has already turned red.
Red light and stop sign violations are misdemeanors in Wyoming. Generally, the fines are:
Although these violations can lead to jail time, most violations involve just a fine.
Depending on the circumstances, a red light or stop sign violation could lead to a reckless driving conviction. And a driver who runs a red signal or stop sign and ends up killing another person could face "homicide-by-vehicle" charges.
