The National Motorists Association did a study and found that six U.S. cities have shortened the length of the yellow light at intersections that have red light cameras. Cities such as Union City, CA, Dallas and Lubbock, TX, Nashville and Chattanooga, TN, Springfield, MO have reduced the length of the yellow light below the U.S. national standard minimum of 3 seconds.

Red light cameras which are used to photograph motorists who illegally enter an intersection on a red light. Tickets are issued to the registered owner of the vehicle.

Motorists 'running the red' have been the cause of major accidents both with other vehicles and pedestrians. However installation of red light cameras did not reduce the number of accidents at an intersection. A study conducted by the Ministry of Transportation (Evaluation of the Red Light Camera Enforcement Pilot Project 12/1/2003) concluded that red lights cameras actually cause more accidents.

There were 4988 reported collisions at the 48 evaluation study sites in the before period. An average of1027.6 collisions/year. In the after period, there was a total of 2366 reported collisions. An average of 1183.0 collisions/year. This was an increased 15.1%.

Red light cameras have been found to cause more rear-end collisions as drivers come to a sudden stop to avoid entering the intersection on a yellow light.

Red light cameras are also used as a revenue stream for crash strapped cities. Fines for red light violations in Toronto are $190. Hopefully Canadian cities do not follow the U.S. example and tamper with red light cameras for increased profits.

Driving through a red light intersection can be an expensive prospect. Chances are you might get a red light ticket or a rear end collision.

Your GPS can be programmed to alert you to a red light camera intersection. A list of all the red light camera intersections and the GPS data files can be found here.
