Staying awake on long drives — District of Columbia Permit Test
Staying awake on long drives on the District of Columbia permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
At the first signs of drowsiness, do something positive; do not just sit there and try to fight it.
Willpower alone does not keep a sleepy driver awake, so waiting it out only lets it get worse.
At first signs of drowsiness, do something positive. Don’t just sit there and try to fight it.
At the first rest or service area, pull off the highway and take a nap, stretch, take a break or, if possible, change drivers.
Stopping is the one sure way to keep a tired driver from drifting off at speed.

Do not depend on "stay-awake" drugs; they are apt to make your driving even more hazardous.
A pill can hide how tired you are without making you any safer, and it can throw off your judgment.

To avoid highway hypnosis, keep the inside of the car as cool as possible.
A warm, stuffy car makes you sleepy, and cool air helps keep you alert.

Keep shifting your eyes from one area of the roadway to another, near and far, left and right, and avoid staring straight ahead.
Staring at one spot is how highway hypnosis takes hold; moving your eyes keeps your brain working.

On a long drive, vary your vehicle's speed slightly from time to time.
Holding one speed for hours adds to the sameness that lulls you into highway hypnosis.

On the test
What should you do at the first signs of drowsiness?
Do something positive about it. Willpower alone does not keep a sleepy driver awake, so waiting it out only lets it get worse. DC Driver Manual, p.38: “At first signs of drowsiness, do something positive. Don’t just sit there and try to fight it.”
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.
