Safety Inspections
Although billions of dollars are spent annually on designing and constructing safe highways, testing and licensing drivers, and enforcing traffic laws, some jurisdictions do not conduct vehicle safety inspection programs. AAMVA promotes periodic motor vehicle inspections (PMVI) to ensure that vehicles are maintained for safe operation.

Emissions Inspections
Internal combustion engines used in most of today's vehicles are a significant source of man-made air pollution. These engines produce four types of emissions that can be regulated through emissions inspection and maintenance (I/M) programs:
- hydrocarbons
- carbon monoxide
- oxides and nitrogen
- particulates
Implementation of I/M programs is mandatory in the United States in those areas that are not in compliance with the National Ambient Air Quality Standards (NAAQS), under provisions of the 1977 Clean Air Act.
