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 specifically 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.
