Any child under the age of nine must be properly fastened in an approved child safety restraint seat when riding in a vehicle. The child cannot be placed in the front seat, unless the vehicle doesn’t have a rear row.

The only exception is if a doctor excuses the child from this requirement with a written statement. The statement must be carried in the vehicle the child is riding in at all times.

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.
