Health Tip: Put the Brakes on Drowsy Driving

(HealthDay News) -- Nodding off may be okay while you're chaperoning a kiddy movie or at your mother-in-law's birthday party, but not when you're behind the wheel.

The National Sleep Foundation says these warning signs mean you're too tired to drive:

• Having difficulty focusing, heavy eyelids or frequent blinking.

• Daydreaming or wandering thoughts.

• Missing traffic signs or exits, or inability to remember the last few miles that you drove.

• Rubbing your eyes, yawning, or difficulty holding your head up.

• Drifting in and out of lanes, driving over a rumble strip, or riding too close to the car in front.
