The incidents are increasing of law enforcement officers, emergency medical services, fire department personnel, and tow truck operators being struck while performing duties on the road. To lessen this problem, SC and most other states, have enacted move-over laws, which require drivers to slow down and change lanes when approaching emergency vehicles.
When you approach a stopped authorized emergency vehicle, proceed with caution. Slow down and yield the right-of-way by making a lane change into a lane away from the authorized emergency vehicle, if safety and traffic conditions permit. If a lane change is unsafe, slow down and proceed with caution while maintaining a safe speed for traffic conditions.
