Expect the unexpected. Drive with caution, and watch for workers. Don't change lanes unnecessarily. Avoid changing radio stations and using mobile phones while driving in the work zone. Turn on your headlights so that workers and other motorists can see you.
Night work is possible in some work zones.
Expect delays, especially during peak travel times and during holidays. Allow ample space between you and the car in front of you. Anticipate lane shifts, and merge when directed to do so.
