Wyoming Speeding Laws

Wyoming has what is known as an “absolute” speed limit law. There is no trick to how this works: If the sign says 40 mph and you drive 41 mph or more, you have violated the law. In other words, you are guilty if you drive over the speed limit. In Wyoming you may be able to make three possible defenses:

• Attacking the officer’s determination of your speed. To do this you must discover what method the officer used to cite you and then learn about the ways to attack that particular method.
• Claiming an emergency forced you to exceed the speed limit to avoid serious damage or injury to yourself or others.
• Claiming that the officer mistook your car for another car. With so many similar-looking cars, it is possible that a cop could see a speeding car, lose sight of it around a corner, and then wrongly pick out your car farther down the road.

Note that in Wyoming you can be ticketed for driving at an unsafe speed, even if that speed does not violate the posted limit -- for example, driving exactly at the maximum mph posted limit on the freeway amidst slower and heavy traffic, in a dense fog, or in a driving rainstorm or blizzard.
