Is there an annual vehicle safety inspection?

From a federal push to a state choice

Pennsylvania started the first state safety inspection program in 1929, according to a 2015 report by the U.S. Government Accountability Office (GAO). Maine and Massachusetts followed in 1930. The federal government got involved after the Highway Safety Act of 1966. In 1967 the Department of Transportation issued its first standards for state highway safety programs, and one of them called for periodic vehicle inspections. A state that didn't run a highway safety program could lose 10% of its federal highway aid.

Inspections peaked in the mid-1970s, when 31 states and the District of Columbia required them. A 1976 law limited the federal government's power to withhold highway money, and since then each state has been free to decide. GAO counted 16 states with periodic inspections in July 2015. At that time the National Highway Traffic Safety Administration (NHTSA) still recommended that every state periodically inspect all registered vehicles, but only as a guideline, not a requirement.

A shrinking list

Ten states dropped out between 1976 and 1982 alone, including Colorado, Florida, Georgia and Kentucky. Later, South Carolina ended its program in 1995, Oklahoma in 2001, the District of Columbia in 2009 and New Jersey in 2010. Officials often pointed to a lack of evidence and to cost: GAO quotes a 2001 Oklahoma Senate release that expected repeal to save Oklahomans $12 million, and New Jersey's motor vehicle chief estimated $17 million a year in savings.

More states have dropped out since GAO's report. Mississippi repealed its inspection law effective July 1, 2015, and Utah stopped requiring inspections for most passenger vehicles on January 1, 2018. Texas ended safety inspections for non-commercial vehicles on January 1, 2025. Owners there now pay a $7.50 inspection program replacement fee at registration instead. New Hampshire's inspection law was repealed effective January 31, 2026.

More changes are on the way. Louisiana's Act 701 of 2026 limits regular inspections to commercial and student transportation vehicles starting January 1, 2027. In parishes covered by federal Clean Air Act rules, the change waits for EPA approval. The act also bars tickets for a missing inspection sticker from June 30, 2026, to January 1, 2027, and creates a separate Louisiana Vehicle Identification Program sticker that shows the car's VIN. West Virginia eased its rule instead, moving from yearly to every-two-year inspections on January 1, 2024. In Missouri, a 2026 effort to end most inspections did not become law.

What an inspection checks

NHTSA's Vehicle In Use Inspection Standards set minimums for brakes, steering, suspension, tires and wheels. Tire tread, for example, must be at least 2/32 of an inch deep. GAO noted in 2015 that those standards were last updated in 1979, so newer equipment such as anti-lock brakes isn't covered. States add their own checks, usually lights, seat belts, horns, windshields, wipers and the underside of the car.

Newer technology makes the job harder. States set different pass-fail rules for LED brake lights, which use many small diodes. As of 2015, five states required at least half of the diodes to work, one required 70%, and three required all of them. Some states are narrowing what counts as a failure: Vermont's 2026 law (Act 153) directs its DMV to fail cars only for problems that pose an immediate safety risk.

In most inspecting states, the work is done by private garages that the state licenses. Delaware is the exception: the state DMV runs its own inspection lanes and charges nothing. In 2015, GAO counted about 295 licensed stations in Rhode Island and about 17,000 in Pennsylvania. Fees ran from $0 in Delaware to $55 in Rhode Island, where the fee also covers an emissions test.

Many inspecting states exempt some cars. Hawaii and Rhode Island give a new car up to two years before its first inspection. Delaware can waive inspection for cars up to seven model years old, and Missouri exempts cars for ten years after their model year if they have fewer than 150,000 miles. Antique and historic vehicles are often exempt too. GAO reported that two states exempted newer cars or dropped minor checks as a compromise to keep their programs alive.

Do inspections prevent crashes?

GAO reported that in 2014, more than 529,000 vehicles in Pennsylvania, about 20% of the state's registered vehicles, failed inspection and were repaired to pass. Virginia officials said their program found safety problems in over 1.4 million vehicles that year, about 19% of the state's fleet, including about 700,000 rejected for brake problems.

Whether that prevents crashes is less clear. GAO's analysis of NHTSA crash data from 2009 to 2013 found a vehicle component failure noted in about 2% of crashes, most often tires, then brakes, then steering. A more detailed NHTSA study of more than 5,000 crashes from 2005 to 2007 found component failures present in 6.8% of them, but the Department of Transportation says a failure was the critical reason for a crash in only about 2% of cases, compared with 94% for the driver.

None of the three U.S. studies published since 1990 that GAO reviewed found a statistically significant difference in crash deaths or injuries between states with and without inspections. In New Jersey and Oklahoma, the share of crashes involving equipment failure stayed between 2% and 3% after inspections ended. GAO cautioned that this does not prove inspections have no effect, because police crash reports can miss mechanical causes. The Department of Transportation adds a caveat in the other direction: reported failures are often based on drivers saying their brakes failed, without verification. Officials in Rhode Island, Vermont and West Virginia told GAO that road salt and rough roads wear cars out faster, which they see as a reason to keep inspecting.

Inspections at sale, VIN checks and moving

Maryland takes a different approach. It doesn't inspect cars on a schedule, but a used car needs a safety inspection certificate from a licensed station before it can be titled and registered, including when it's sold or brought in from another state. The certificate is good for 90 days. New York requires its yearly inspection and also requires one when a car changes owners.

Moving into an inspecting state usually starts a clock. Massachusetts requires a newly registered car to be inspected within seven days, West Virginia within 10 days of titling, and Vermont within 15 days. Virginia requires cars brought from another state to be inspected after they are registered there.

Many states that have no safety inspection still look at a car when it arrives from another state, but only to check its vehicle identification number (VIN) against the paperwork. Colorado, Florida, Idaho, Kansas, Ohio, Oregon, Wyoming and others do this. A VIN check confirms the car's identity, not whether its brakes or lights work, so it doesn't count as a safety inspection on this map.

Emissions tests and trucks follow other rules

Emissions testing has a different legal basis. Federal Clean Air Act rules require vehicle inspection and maintenance programs in areas that don't meet federal standards for ozone or carbon monoxide, depending on population and how bad the pollution is. Even after an area's air improves, a program must keep running until the EPA approves a revised state plan showing the area can stay within the standards without it. That is why North Carolina's 2023 and 2026 laws removing counties from emissions testing, and Louisiana's inspection changes in some parishes, wait on the EPA. North Carolina's annual safety inspection stays either way.

So a state with no safety inspection may still require an emissions or smog test, often only in certain counties or metro areas. California requires smog checks at renewal in 34 counties; Arizona tests in parts of Maricopa, Pinal, Yavapai and Pima counties; and Colorado, Georgia, Nevada, Oregon, Utah and Indiana test in specific counties or regions. New Jersey inspects passenger cars only for emissions, every two years.

Commercial trucks and buses are another category. Federal motor carrier rules require each commercial motor vehicle to pass an inspection at least once every 12 months, and an inspection under a state program meeting the federal minimums counts. Texas still requires safety inspections of commercial vehicles in every county, and Utah still requires yearly inspections of commercial vehicles, even though ordinary cars are exempt in both states. West Virginia inspects cars every two years but certain commercial vehicles every year under the federal rules.

Cars still have to meet equipment laws in states with no inspection program. Florida, Michigan, Montana and Nevada let police stop and inspect a car they have reason to think is unsafe, and Minnesota runs roadside spot checks.
