Watch Out for the Other Guy
Drivers using a little caution at intersections with traffic signals can prevent many accidents. If you are the first car in line at an intersection waiting to go, DO NOT just take off when the light turns green. If you move forward without looking you could easily be involved in an accident with a car running the red signal. The traffic signal turning red does not force the other cars to stop, it just tells them to stop.
This accident is easily prevented by looking to the left and right to make sure some other driver is not running the red light before you move forward. Also, make sure you are not the one running the light and causing the accident. Sometimes we have to watch out for the other guy. Please drive carefully.
