Running a red light is illegal in all states and a ticket or citation for the infraction or offense may lead to a significant fine, demerit points on a driver’s license or driving record, and increased insurance premiums (upon conviction, guilty plea, or plea of no contest).

Due to limited resources many states use automated red-light cameras—also known as photo enforcement—to take a digital photograph of a vehicle (and its license plate) that violates the red light or traffic signal by entering the intersection and failing to stop after the light has turned red. The use of red-light cameras to issue traffic tickets or citations (mailed to the driver) has been controversial, with claims that it violates Constitutional rights.

Laws vary from state to state and in some states red-light cameras are a permitted enforcement tool; in some states they are prohibited; and in some states they are prohibited unless permitted by a local ordinance (city or town).

In Alabama, running a red light is considered a traffic violation and is illegal under state law. Violators can face fines, points on their driving record, and potentially higher insurance rates. Alabama does permit the use of automated red-light cameras to enforce traffic laws. However, the use of these cameras has been a subject of debate, with some arguing that they may infringe on constitutional rights. The implementation of red-light cameras can vary by locality, and it's important for drivers to be aware of the specific regulations in their area. As of my knowledge cutoff in 2023, drivers in Alabama should exercise caution and adhere to traffic signals to avoid penalties associated with red-light violations.
