Sometimes I pull up to a traffic signal and the light does not change to green. Why is this?
More and more intersections with traffic signals are being installed with vehicle detection loops. When you pull up to a traffic signal that has a vehicle detection loop, you must actuate the loop by stopping on the stop bar. To learn more, visit the Vehicle Detection Loops page.
