Motor vehicles; modifying requirements related to safety belts. Emergency.

Oklahoma Senate Bill 117 updates the state's safety belt law to require front-seat passengers in commercial vehicles (like trucks and buses) and all passengers in passenger vehicles (excluding motorcycles, farm vehicles, and trucks) to wear seat belts. It adds a medical exemption process where a physician's written attestation allows a driver to skip the requirement, with the exemption noted on their license. The bill limits fines for violations to $20 and clarifies that municipalities cannot enforce stricter seat belt rules than the state law. It also declares an emergency to take effect immediately upon approval.
