Do photo enforcement flash units cause collisions?
No. The flash duration is less than 1/2000th of a second. That is shorter than lightning due to weather. The intensity of the flash is no brighter than any camera one might purchase for personal use. The height of the pole, shape of the reflector, and distance to motor vehicles and pedestrians also minimize the effect of the flash. In the last 10 years there has not been a single reported incident of flash causing a collision. If anything, photo enforcement flash has a positive effect on driver behavior. It provides instant feedback to those who speed or run red lights, and most react by slowing down.
