What States Require Vehicle Safety Inspections

Vehicle safety inspections serve many purposes, including ensuring that the vehicle you intend to purchase is in proper working condition. In the United States, vehicle inspections are mandated by individual states to ensure that cars on the road meet safety and emissions standards. But for some states, these inspections aren't optional. If your vehicle fails a safety inspection in a state with legal requirements, you'll need to perform repairs to bring it back into compliance. If you don't, you may be subject to fines or other penalties until your car can pass an inspection.

What States Do Not Require Vehicle Inspections?

There are only 13 states that have no safety, emissions, or VIN inspections required by law. These states include Alaska, Arkansas, Iowa, Michigan, Minnesota, Mississippi, Montana, North Dakota, South Carolina, South Dakota, Florida, Washington, and Wyoming. Some of these states do require an inspection when registering an out-of-state vehicle for the first time. Still, for regular inspections of vehicles owned by residents, there are no annual or biennial inspections.

For states with vehicle inspections, various requirements must be met to stay in compliance.

What Does State Inspection Check?

Requirements vary for different states with vehicle inspections; however, some standard components are checked by most jurisdictions, including:

Brakes: As one of the most critical basic safety systems, brakes are high on the list for a general inspection. Most inspection stations will check the pads and rotors to see if they are worn, along with your brake fluid levels. In addition to your regular brakes, your emergency brake will also be checked. Worn-down or non-functioning brake elements will usually result in an inspection failure.
Tires: Much like with your brakes, vehicle safety inspections will check how worn down your tires are and if they contain any defects. These defects include damage,dry rot, or abnormal formations that could result in the tire going flat or exploding during travel. Be careful; an inspection technician won't only check the tires on your vehicle; if you have a spare tire, the tech will need to confirm its condition as well for you to pass your inspection.
Lights: Vehicle safety inspections will almost always check the various lights on your car, including your headlights, brake lights, taillights, hazard lights, and turn signals. If any one of these is burnt out or dim, it's a strong possibility you will fail your inspection.
Mirrors: Your side view and rear mirrors are vital to maintaining awareness of the vehicles around you while traveling, and inspections will ensure these are not broken, streaked, or obscured in any way. Read-view mirror cameras can be checked as well.
Suspension: To pass a vehicle safety inspection, your suspension system, including your shock absorbers, must be free of leaks and damage. Without a properly functioning suspension, your car could be damaged by poorly maintained or rough roads, putting it at risk of mechanical failure.

Toughest Inspection States

A few states have significantly more stringent vehicle safety inspection laws, but Rhode Island may have the toughest. Residents of this small state must get biennial safety and emissions testing, and antique cars (which are exempt in many states) still need to be inspected. The extensive list of checks, which includes reflectors, ABS brakes, universal joints, and many more, must be done at a designated inspection station. The only vehicles that are exempt are new cars, but that exemption lasts only two years until the biennial requirements kick in.

What States Require Smog Checks?

Smog checks, also known as emissions tests, are required in several states across the U.S. to help control air pollution and ensure vehicles meet environmental standards. States like California, Nevada, and Arizona have stringent smog check requirements due to their significant urban populations and air quality issues. These tests typically involve measuring the levels of pollutants emitted from a vehicle's exhaust system. States with smog check requirements aim to identify vehicles that are high polluters and ensure they are repaired or removed from the road. It's important for vehicle owners to be aware of their state's smog check regulations to maintain compliance and contribute to cleaner air.
