Vehicle inspection in the United States
In the United States, vehicle safety inspection and emissions inspection are governed by each state individually. 17 states have a periodic (annual or biennial) safety inspection program, while Maryland and Alabama require a safety inspection prior to registration or transfer of ownership only. Nebraska requires safety inspection only upon newly arrived vehicles which were previously registered in another state. New Jersey discontinued its passenger vehicle safety inspection program on August 1, 2010.
Under the Clean Air Act (1990), states are required to implement vehicle emissions inspection programs, known as I/M programs (for Inspection and Maintenance), in metropolitan areas whose air quality does not meet federal standards. The specifics of those programs vary from state to state. Some states, including Kentucky and Minnesota, have discontinued their testing programs in recent years with approval from the federal government.

Jurisdictions requiring periodic vehicle safety inspections
- Delaware—annually or biennially, new cars are exempt from inspection for the first five years provided the car remains with the same owner.
- District of Columbia—biennially, the requirement for safety inspection for privately owned cars ended October 1, 2009.
- Hawaii—annually, with the following exceptions: Brand new vehicles receive an inspection valid for two years. Emergency vehicles, school vehicles, rental cars, and vehicles used in public transportation must be inspected every six months. Sticker placed on rear bumper to right on license plate.
- Louisiana—annually. However, as of September, 2012, people in most jusrisdictions have the option of getting a sticker good for two years, rather than one, by paying double the usual fee. Note that, in Louisiana, Inspection Stickers are commonly referred to as "Brake Tags"; they are placed on the inside of the windshield, in the lower-left corner of the windshield (on the driver's side). Colors change every year.
- Maine—annually; color of sticker changes annually; Sticker placed in top center of windshield behind rear view mirror.
- Massachusetts—annually. Stickers are placed in the lower right corner of the windshield.
- Missouri—biennially, based on the vehicle's model year. Odd-numbered model year renews in odd-numbered year, even-numbered model year renews in even-numbered year. New vehicles not previously titled are exempt from inspection during the vehicle's model year and the year following. Vehicles displaying historical plates are completely exempt from inspection.
- New Hampshire—annually, except the first inspection of a new vehicle or upon an ownership transfer is adjusted to expire in the month of the registrant's birthday and is therefore valid for 4 to 15 months. Sticker placed in top center of windshield under rear view mirror.
- New Jersey—annually for commercial vehicles (including taxis, limosines, jitneys, and buses), effective January 1, 2010. Passenger vehicles are exempt from safety inspections, effective August 1, 2010.
- New York—annually. Newly registered vehicles with a current inspection sticker from another state are exempt until the out-of-state sticker expires or for one year after registration in New York, whichever is sooner. Stickers are placed on lower left corner of windshield.
- North Carolina—annually until the vehicle is 35 years of age, at which point inspections are no longer required.
- Pennsylvania—annually for most vehicles; every six months for all vehicles over 17,000 pounds (7,700 kg) GVW, which includes tractor-trailers, most non-articulated trucks, school vehicles (including school buses and school vans), motor coaches, mass transit buses, ambulances, fire department trucks, etc., and even though they fall below that gross vehicle weight, taxicabs and most vehicles that carry passengers for hire. Limousines are inspected annually, although they carry passengers for hire. Annual inspection (AI# serial numbers, which become BI# when AI# is exhausted at 10 million stickers), emission (IM#), and semi-annual (SI#) inspection stickers are color-coded - each type of sticker has its own distinct color which is changed at random every year (for example, colors for stickers expiring from October 2013-September 2014 are as follows: annual inspection-blue, annual emissions-red, semiannual inspection-yellow; colors for stickers expiring from October 2014-September 2015 are as follows: annual inspection-green, annual emissions-orange, semiannual inspection-purple). Stickers are placed on the lower left corner of the windshield. The new issue stickers appear in October in time for the January expiration stickers to be available on their first day of issue, which is November 1 of the previous year, for example, stickers bearing an expiration date of January 2015 will be available starting on November 1, 2013 (new stickers are available 3 calendar months before the current sticker's expiration). The annual color change makes it easier for police to be aware of expired stickers. Vehicles bearing antique vehicle license plates are exempt from inspection, but vehicles bearing classic or collectible license plates are subject to inspection. Trailers in excess of 3,000 pounds (1,400 kg) GVW are also inspected annually as are motorcycles.

Inspection stickers are placed behind the rearview mirror and are color-coded by year.
- Virginia—annually;. Newly registered vehicles with a valid inspection from another state are exempt from inspection until the out-of-state inspection expires. Stickers are yellow and are placed in the lower center part of the windshield.
- West Virginia—annually; color of sticker changes annually; sticker placed in lower left corner of windshield.
