(CNN) – Ever wish you could rig the traffic lights to be green during your commute? Turns out, it may not be that hard to do.

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

Under the supervision of local transportation officials, computer researchers were able to change traffic lights in an undisclosed Michigan city in May, just using a laptop in their truck.

The make of the traffic light's equipment manufacturer is not named in the study, but CNN Money has independently confirmed that the lights and controllers are made by Econolite, one of the largest makers of signals, cameras, and traffic management systems in North America.

Econolite's traffic lights are used in 100,000 U.S. and Canadian intersections. It's unclear if all those systems are susceptible to hacking.

The company did not respond to CNN's request for comment.
