    Safety Tips for Driving Through Work Zones

    • Pay attention - driver inattention is the number one cause of work zone accidents.
    • Leave room between you and the car ahead of you - most work zone accidents involve someone running into the car ahead of them.
    • Drive defensively - be aware of what is happening around you.
    • Merge into the proper lane before you reach the work zone.
    • Don't use cell phones or adjust your radio while driving.
    • Avoid work zones by using alternate routes
