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 Arkansas, 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. Arkansas has specific statutes regarding the use of automated red-light cameras. As of the knowledge cutoff in 2023, Arkansas law prohibits the use of these cameras to enforce red-light violations statewide. This means that no automated tickets can be issued for running a red light based on photographic evidence alone. Enforcement of red-light violations in Arkansas is carried out by law enforcement officers who witness the offense. It's important for drivers to understand that despite the prohibition of red-light cameras, running a red light is still a punishable offense under Arkansas traffic laws.
