Indiana DOT testing signs to help drivers avoid red lights

By Bill Holloway

Indiana DOT is beginning to test dynamic message signs that tell drivers how fast to go to avoid hitting a red light. According to INDOT spokesperson Harry Maginity, the signs are currently located only along State Road 37 in Morgan County, starting about 2 miles ahead of the intersection with State Road 144.

While dynamic speed limit signs have been used elsewhere, Indiana is the first state to use dynamic signs to advise drivers about how fast to travel to make the next green light. INDOT‘s primary goal for the new signs is to reduce the likelihood of rear-end collisions at traffic lights. However, they are also hoping that the signs will help to increase efficiency and save fuel.

If they prove effective, INDOT will likely deploy them in other locations.
