When severe weather strikes in the area, there is a chance traffic signals can lose power. The Indiana Department of Transportation has technicians on 24 hours per day to manage these issues.
Under Indiana law, drivers who encounter an intersection where the signal has lost power should treat the intersection as a four way stop. After stopping and when it is safe to do so, the driver should proceed with caution through the intersection. Drivers should yield to the right of way of traffic already in the intersection.
