What vehicles are required to be inspected biennially?

The requirement for vehicles to be inspected biennially pertains specifically to farm vehicles. In Pennsylvania, farm vehicles have unique regulations and inspection schedules, and they are often subject to inspections every two years to ensure they meet safety and operational standards. This regulation recognizes the varied uses of farm vehicles and helps promote safety while accommodating the agricultural sector's needs.

In contrast, school buses and certain larger commercial vehicles typically undergo inspections more frequently to ensure the safety of passengers, while passenger cars and light trucks usually have annual inspection requirements rather than biennial. Understanding these distinctions is crucial for complying with safety regulations and ensuring that all vehicle categories receive appropriate oversight.
