Study Says Traffic Lights Easy To Hack

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 US 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 name of the traffic lights' equipment manufacturer is not named in the study.

But CNNMoney has independently confirmed the lights and controllers are made by Econolite, one of largest makers of signals, cameras and traffic management systems in North America.

Econolite's traffic lights are used in 100,000 US and Canadian intersections.

It's unclear if all of those systems are susceptible to hacking.

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