Drowsy driving — Virginia Permit Test
Drowsy driving on the Virginia permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Constant yawning, heavy eyelids, missing exits, drifting between lanes and not remembering the last few miles are all signs of drowsy driving.
By the time you notice them you have already been driving while half asleep.
Constant yawning, head nodding, heavy eyelids, difficulty remembering the last few miles driven, missing road signs or exits, unplanned lane changes, driving off the road or hitting rumble strips are all signs of drowsy driving.
On a long trip, stop to rest at least every two hours.
Tiredness builds quietly, and the break resets it before it matters.
Limit long distance driving. Stop at least every two hours for rest.
A nap of as little as ten to twenty minutes at a safe place can make a real difference to drowsiness.
Sleep is the only thing that actually fixes being tired.
Stop at a safe place and take a nap. As little as 10 to 20 minutes of sleep can make a big difference.
Opening a window, chewing gum, turning up the radio or drinking caffeine do not prevent drowsy driving and are not reliable ways to stay awake.
They make you feel more awake for a few minutes without making you any safer.
Rolling down a window, chewing gum, turning up the radio, or consuming caffeine, energy drinks or other stimulants do not prevent drowsy driving and are not reliable methods for staying awake.
Avoid driving between 10 at night and 6 in the morning.
Your body expects to be asleep then, whatever your plans are.
Avoid driving from 10 p.m. to 6 a.m.
On the test
Which of these is a sign of drowsy driving?
Not remembering the last few miles driven. By the time you notice them you have already been driving while half asleep. Virginia Driver's Manual, p.24: “Constant yawning, head nodding, heavy eyelids, difficulty remembering the last few miles driven, missing road signs or exits, unplanned lane changes, driving off the road or hitting rumble strips are all signs of drowsy driving.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
