Maine requires a yearly safety inspection. The same checklist matters for your road test: the examiner won't test you in a vehicle that fails it. Learn the numbers for horn, brakes and tires.

Know the rule

Every Maine-registered motor vehicle must have a current Maine inspection before being operated on any public way. Inspections are done once a year at an official inspection station.

Handbook p. 20 ↗

Know the rule

No current inspection sticker can mean a fine and loss of points on your license. Motorcycles must have a valid sticker too, and a police officer may inspect a vehicle at any time, including at legal roadblocks.

Handbook p. 20 ↗

Know the rule

A vehicle safety check is part of the driver exam. No exam is given if the vehicle fails inspection criteria, any door doesn't work, seats aren't secured to the floor, or the glove compartment door won't stay closed.

Put it into practice

You show up for your road test and the glove box keeps falling open. The examiner will refuse to give the test until it's fixed, even if the rest of the car is in perfect shape.
