Traffic Safety Laws in Wyoming

Seat Belts

With few exceptions, everyone riding in a vehicle and older must wear a seat belt. Passengers who are 9 years old and under must be in a child restraint safety seat.

It's up to the driver to ensure all passengers follow this rule.

The only exceptions:

  • U.S. postal employees when acting as mail carriers
  • Anyone with a doctor's note excusing them from wearing a seat belt
  • Anyone unable to obey the law due to all seat belts being in use
  • Anyone riding in a vehicle that isn't required to have seat belts

Child Car Seat Laws

Children must be properly restrained whether in a rear-facing, forward-facing, or booster seat. Depending on the age, weight and height of your child, you will have different requirements. Generally children 8 years old and younger must be in a child seat in the back of the car.

For information on Wyoming child restraints, see the National Highway Traffic Safety Administration guidelines.

Before you purchase a child car seat, be sure to read our articles on How to Install a Child Safety Seat and How to Buy a Child Safety Seat.

Cell Phones and Texting

In Wyoming, texting on your cell phone is banned for all drivers, regardless of age or driving experience.

If you are a new driver, you are also banned from any use of a cell phone, even if you are using a hands-free device. For more information on cell phone usage while driving,contact the Wyoming Department of Transportation.


Minors must wear an approved helmet when operating or riding a motorcycle.

Unsafe Drivers

To report possible drunk or other unsafe drivers, or other types of highway emergencies, call the Wyoming Highway Patrol at (800) 442-9090.

Call 911 or your local police department for non-highway emergency situations.

Unattended Children

While Wyoming doesn't have any statewide laws specifically addressing the issue of leaving children unattended in a vehicle, the state considers it to be child endangerment for a caregiver to knowingly or with criminal neglect violate their duty of care, protection, and support of a child's life or health.
