Prevention — Before you embark on a trip, you should:

Get enough sleep.
Plan to drive long trips with a companion.
Schedule regular stops for every 100 miles or two hours. . . .
Actions for the drowsy driver — once driving, you must:

Recognize that you are close to sleep and cannot calculate when sleep may occur.
Not depend on the radio, open [the] window, or [do] other "tricks" to keep you awake.
Pull off into a safe area from traffic and take a brief nap (15 to 45 minutes).
