OK so it's really late at night and you pull up to a traffic light and it's red. You are waiting and waiting and there are no cars around.

I've heard if you flash your high beams that will help make the light turn green.

I've also heard if you drive close to the pedestrian crosswalk and back up it can trigger some kind of sensor.

So are these urban legends? What's the truth?

You can't make the light change by flashing your headlights. That's urban legend.

There is a sensor cut into the pavement of most intersections, and sometimes they don't pick up just one car, so yes - moving the car can sometimes help.

Most are magnetic. If you're caught at a particularly long light and there's no one behind you, pull up to just before the x-walk, reverse a couple of car lengths, then pull up again. It makes the magnet think people are running the light. This usually works only very early in the morning, like 3-4 AM when the lights are otherwise programmed on a very slow cycle. Some do have a light sensitive sensor. Some also have a motion sensitive sensor to detect when a car is pulling up. Most "traffic cameras" are actually these motion sensors. The easiest way is just hunt in your glove box for something. This works without fail. LOL

some intersections have buried sensors. IF there are pedestrian controls located on the corners, there is usually lane sensors. If you don't see any pedestrian buttons, probably no sensors. BUT if you look above the signal lights and see a small tube pointed down the highway, each direction, cross direction, etc, you may have an out. Some time soon, when you see and emergency vehicle, note if they always get the green...if so, that little "tube" has an optical sensor in it to force the light green depending upon oncoming emergency traffic. YOU will have to get a technician to build you a signal flash emitter so you too can force the green. Lots of technical stuff and expensive!!!!

They are all hoaxes. Just wait it out. Make sure you windows are locked for security. Traffic lights are still too dumb to support that kind of image recognition. If you keep trying stuff, soon, it's your turn to get a green and whatever you just tried may appear to have worked.

Make it jealous!!! Seriously, if it bothers you to wait for the light to change and there is no one around, make a right turn on red, then make a U-turn, then make another right turn, red or green.

The only way that I know is to wait for it to turn green.

How do you make the light turn green? wait, and wait, and wait, and wait, and wait, and wait, and wait, and, well, do you get my point?
