Red-light cameras are usually mounted on poles at all four corners of intersections in order to obtain photographs from multiple directions and different angles. They are meticulously maintained and engineered to accurately capture red-light running violations and intersection collisions. The technology is complex. There are three essential elements associated with red-light cameras: (1) one or more cameras with battery such as Canon & Nikon Flash Speedlite SL-566, Canon & Nikon SL-568 Flash Speedlite , RF550/e SLR Cameras Macro LED Ring Flash Light, HVL-LBPB Video Light, LED-160A Video Camera Light, LED-187A Video Camera Light, LED-336A Video Camera Light, LED-336 Video Camera Light, LED-540A Video Camera Light, LED-540 Video Camera Light, (2) one or more triggers and (3) a computer. There are typically two induction loop triggers located underground near the crosswalk or stop line, which are used to detect when a vehicle moves past a specified point on the road. This is known as the “detection zone.” The computer serves as a monitor between the triggers and traffic lights. When a vehicle drives over the triggers in excess of a certain speed while the light is red, the triggers are set off and essentially send a signal to the computer to initiate the cameras to photograph the vehicle as it proceeds through the intersection. To trigger the computer, a vehicle must travel over both induction loop triggers at a particular speed. The computer superimposes information onto each photograph such as the date, time, location, speed the vehicle was traveling and the elapsed time between the light turning red and the vehicle entering the intersection. Accordingly, the computer is also programmed to ignore the triggers during the period of time when the lights are green or yellow. There is usually a grace period of approximately half a second once the light turns red, along with a particular speed which a vehicle must be traveling at, to help the computer differentiate between vehicles who are simply attempting to stop and make a right turn on red and those who are clearly running a red light.
Red-light cameras are designed to capture multiple types of violations including turning right without coming to a complete stop, illegal right-hand turns, turning left on a red light, and going straight through a red light. They also catch motorists who violate traffic regulations by blocking intersections, failing to stop at stop signs or behind a stopped school bus, failing to pay a toll, or disobeying railroad crossing signals. Many jurisdictions treat citations issued in accordance with a red-light camera image in much the same way as a general parking ticket; typically, the registered owner of the vehicle is liable regardless of who was driving. Points are generally not assessed against the driver nor does the violation show up on the motorist’s driving record. Citations are issued only upon clear evidence of a traffic violation. Tickets are not automatically issued to every vehicle captured by the red-light cameras. Rather, a trained police officer or other authorized person must review the photos or video footage prior to any citation being issued. Depending on the particular state laws, red-light cameras may be set up to photograph only the rear license plates of the violating vehicles. In the alternative, some states require an actual photograph of the driver.
As you might imagine, most intersection accidents involving the running of a red light will engage the aforementioned triggers and are likely to produce photographic evidence which can prove one party to the accident a victim and the other a liar. It is like Christmas for trial lawyers.
