Which vehicles are exempt from seat belt regulations?

The correct answer identifies vehicles manufactured before July 1, 1966, as being exempt from seat belt regulations. This exemption is primarily due to the fact that seat belts were not standard equipment in vehicles prior to this date. Regulations have evolved over time, and many older vehicles simply did not come equipped with the necessary safety features, including seat belts, that are now common in modern vehicles. As a result, owners and occupants of these vehicles are not subject to the seat belt laws that apply to newer models.

In contrast, other options presented do not accurately reflect exemptions as outlined in motor vehicle regulations. Vehicles used by government agencies are typically subject to the same seat belt laws as other vehicles, ensuring consistency in safety measures across different types of vehicles. Rideshare vehicles, which are newer models adapted for commercial use, are also required to adhere to seat belt regulations to ensure the safety of passengers. Lastly, while school buses have specific safety regulations focused on passenger safety that differ from those applicable to regular passenger vehicles, they are not wholly exempt from seat belt laws, especially when it comes to newer models designed with seat belts. Thus, the first option is clear and specific in recognizing a defined category of vehicles that fall outside the purview of current seat belt
