Lost sleep from time change can mean a car crash

Warning signs that indicate you need to get off the road include:

• Frequent yawning or blinking
• Driving past your exit or turn
• Not remembering the past few miles driven
• Drifting into other lanes
• Hitting rumble strips

Most crashes that involve drowsy driving happen very early in the morning, after lunch when one has eaten something heavy, or late at night.
