 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.

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 2011-September 2012 are as follows: annual inspection-yellow, emissions-green, semiannual inspection-blue; colors for stickers expiring from October 2012-September 2013 are as follows: annual inspection-orange, emissions-brown).

The annual color change makes it easier for police to be aware of expired stickers.
