What types of vehicles are required to undergo an annual inspection in Maine?

In Maine, all registered motor vehicles are required to undergo an annual inspection. This includes a wide array of vehicle types such as passenger cars, commercial vehicles, motorcycles, and trailers. The annual inspection process is designed to ensure that vehicles meet safety and emissions standards, contributing to overall road safety.

By having this requirement for all registered vehicles rather than limiting it to just passenger vehicles or those of a certain age, the state is able to promote a uniform standard for vehicular safety across different categories of vehicles. This comprehensive approach helps to ensure that all vehicles on the road are in safe operating condition, regardless of their use case.
