Safe & Responsible DrivingStandalone practice
On a night drive, you suddenly realize that you cannot remember the last few miles. You do not feel sleepy. What does this most likely mean, and what should you do?
Correct answer: It is a warning sign of drowsy driving, so stop at a safe place and rest
Why
Other warning signs are hitting a rumble strip or drifting from your lane, yawning again and again, and trouble keeping your eyes open or focused. At 55 mph, a vehicle covers the length of a football field in 3.7 seconds, so even a very short sleep can cause a crash. After you stop, a short nap of 15 to 45 minutes and some caffeine can help, but only for a while.
