What To Know About Vehicle Inspections in All 50 States

Mechanic inspects state inspection checklist

All new vehicles must meet federal smog laws when new. But in 11 of the 50 states, that's it, with no form of further smog or safety inspection required, ever. In 32 states, a smog test is needed to keep cars from polluting as they age. However, surprisingly few states periodically inspect cars for road worthiness.

Have you just acquired an older vehicle, put a car back on the road that has been in storage, or moved into a new state? A few states require a safety inspection for road worthiness on transfer of ownership or when registering from another state, but don’t have a really formal inspection process. Haynes looked into it and has you covered with this state by state with a rundown of requirements, and links to their DMV offices.

Alabama - You only need to have an inspection here with an ownership transfer, and it is done at the DMV, but it seems to be just a cursory inspection since no details can be found online.

Alaska - Despite the beating vehicles take in the largest state from the roads and the weather, there is no safety inspection. It truly is the last frontier with no VIN or smog check either.

Arizona - There are no safety inspections here, and unless you live in Phoenix or Tucson, no smog inspection or test either. 

Arkansas - You can drive whatever you want here, no one at the DMV will care.

California - Despite having some of the strictest smog laws in the country, there are no safety inspections, just a VIN verification. Every two years there is a smog equipment inspection and tailpipe test in 41 out of 58 counties. You can look up your county's requirements here.

Colorado - There are no safety inspections just a VIN verification, and only a few counties have smog tests. If you live or work in Boulder, Broomfield, Denver Douglas or Jefferson, you need a smog test, as well as parts of Adams, Arapahoe, Larimer, and Weld.

Connecticut - You will have to get the VIN verified, but there is no safety check here except for a cursory inspection when transferring registration between owners. However, every two years you do need a smog test.

The DMV checks that all lights work, your brakes are good, your windows aren’t cracked (small cracks allowed in windshield), tires are good, wipers work, mirrors are present, fuel doesn’t leak, latches all work on doors, hood, and trunk, horn is loud, and muffler is quiet. Some things that can fail you: Hood scoop opening more than 3” tall, or a bumper more than 22” above the ground. The full list is here.
