Vehicle Inspection and Maintenance Programs in the United States

This page provides links to information on vehicle inspection and maintenance programs in the United States for interested persons in Mexico

The purpose of this page is to provide selected links to information on vehicle inspection and maintenance programs in the United States for interested persons in Mexico.

More specifically, this site attempts the following:

  • To provide a relatively brief summary of the national context for I/M programs, including only very selected details on most of the 32 states (plus the District of Columbia) that have such programs, plus links to several English-language sites on the website of the U.S. EPA
  • To provide more detailed information on the two largest states on the U.S. border with Mexico—Texas and California (some of this information has been translated into Spanish, but the rest of the information is in English)

It is very important to be aware of two characteristics of these programs in the United States:

  1. Although the legal requirements for most I/M programs in the United States have their basis in federal law (both in statutes and in regulations of the U.S. EPA), the authority to manage such programs is delegated to the states.
  2. In most cases, I/M programs in the United States are implemented only in the specific geographical areas (sub-regions within states) that are in violation of the federal standards for ambient concentrations of certain air pollutants.
