SPRINGFIELD (AP) – Illinois plans to increase its use of speed-indicator boards in construction zones.
An Illinois Department of Transportation pilot program had 13 speed-indicator boards in work areas last year. Radars read oncoming vehicles’ speeds and the boards light up with the measurements. They’re accompanied by a speed-limit sign.
IDOT state safety engineer Priscilla Tobias says the signs now will be mandatory at every road construction zone in Illinois with lane restrictions and workers present.
