How often must vehicles in Maine pass a safety inspection?

In Maine, vehicles are required to pass a safety inspection annually, which means that each vehicle must undergo this process once every year to ensure it meets safety standards. This annual requirement helps to ensure that all vehicles on the road are safe for both the driver and other road users. Regular inspections can identify potential safety issues early on, which can prevent accidents caused by vehicle malfunctions.

The other options suggest different time frames, such as every six months, every two years, or every three years, which do not align with the established regulations in Maine for vehicle inspections. Adhering to the annual inspection timeline is crucial for maintaining vehicle safety standards and overall public safety on the state's roadways.
