Red light running
Camera enforcement works to curb this dangerous behavior.
Automated enforcement refers to the use of cameras to enforce traffic safety laws. Although many states have laws explicitly authorizing automated enforcement, not all states where cameras are in use have such laws, nor are they always necessary.
A common type of automated enforcement program is for red light violations. The use of cameras to enforce speed limits is less common, but increasing. The technology is also used to catch drivers who block intersections or fail to stop at a stop sign, pay a toll, drive past a stopped school bus or disobey a railroad crossing signal. The District of Columbia uses automated enforcement to ticket drivers who fail to yield to pedestrians. In states that have automated enforcement laws, some authorize enforcement statewide, while others permit use only in specified communities.
Many jurisdictions treat automated enforcement citations just like parking tickets in that the registered owner is liable. Similarly, just as parking tickets do not result in points or are not recorded on a driver's record, many jurisdictions do not assess points or make a record of automated enforcement citations.
425 communities have red light camera programs as of January 2017.
