Prepare For Backups
Traffic queues are likely ahead; slow down and be ready to stop.
Congestion or stopped traffic is expected ahead because of the work zone. Ease off the accelerator, increase your following distance, and watch the brake lights of vehicles well in front of you. Rear-end crashes spike at the back of work-zone queues.
