Speed and red light cameras are a type of automated enforcement technology used to detect and deter speeders and red light runners. Some jurisdictions use similar technology for other traffic violations, such as illegal rail crossings or toll violations.
Many states have enacted legislation either permitting, limiting or prohibiting the use of speed or red light cameras at the state or local level. Enforcement can be limited to a particular area or community. Penalties usually are more lenient than those used with traditional enforcement. For example, the fine may be lower, points may not be assessed, or the citation may not go on the driver's record.
Some localities operate speed and/or red light cameras even if the state does not specific permit or prohibit it. The Insurance Institute of Highway Safety maintains a list of all communities operating automated enforcement. This list changes and is updated regularly.
- 13 states have passed laws that prohibit (with very narrow exceptions) the use of speed cameras. 28 states have no law addressing speed cameras. All other states either permit the use of speed cameras (2 + D.C.) or limit their use by location or other criteria (7 + U.S. Virgin Islands).
- 12 states, the District of Columbia and the U.S. Virgin Islands have speed cameras currently operating in at least one location.

- 21 states, the District of Columbia and the U.S. Virgin Islands have enacted laws permitting some form of red light camera use, with 9 states and the District of Columbia fully permitting use, and 12 states and the Virgin Islands allowing limited use. 10 states prohibit their use, and 19 states have no state law concerning red light camera enforcement.
- 24 states, the District of Columbia and the U.S. Virgin Islands have red light cameras currently operating at least one location.
