ANN ARBOR, Mich. (NEWSCHANNEL 3) - Have you wondered if it's possible to rig traffic lights to turn green?

As it turns out, it may not be that hard to do.

According to a study by the University of Michigan, traffic lights across the country are dangerously easy to hack.

Computer researchers, under supervision, were able to change traffic lights in one Michigan city using just a laptop in their truck.

The lights and controllers are made by Econo-Lite--one of the largest suppliers of traffic signals, cameras, and management systems in North America.

Their traffic lights are used in more than 100,000 intersections in the U.S. and Canada.

There is no word yet on how many are susceptible to hacking.
