To require motorists traveling 10 mph or more below the speed limit to activate hazard lights.

HB 4728 requires drivers on interstates and state highways to activate hazard lights when traveling more than 10 miles per hour below the posted speed limit. This law directly affects all motorists operating vehicles on designated highways who are driving significantly slower than the speed limit. The key provision mandates that hazard lights must be turned on in this specific situation to improve visibility. The bill aims to enhance road safety by making slower-moving vehicles more noticeable to other drivers.
