Q&A for How to Trigger Green Traffic Lights

No, triggering a green light through the inductive loop or camera system of vehicle detection doesn't alter the normal, safe schedule of traffic light changes. The cross traffic will always receive a red light just before the light turns green for your to proceed. An accident would only be caused by the fault of a driver running through a red light, some other vehicle malfunction or misbehavior, or the rare occasion of a faulty signal. In the latter case, you should notify authorities immediately of the problem and the location of the affected intersection.

Those cameras are usually triggered when the light turns from yellow to red. If you are already in the intersection (past the legal stop line) when the light turns red, you should be fine. If a police officer is around, he might give you a warning, but you should not get a ticket. The safest thing to do is to get out of the intersection as soon as possible, regardless of what color the light is.

This varies greatly based on what streets are in the intersection and what time of day and time of week it is. Major streets usually have longer green lights than minor streets when they intersect.
