Fatigue and long trips — Montana Permit Test
Fatigue and long trips on the Montana permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
When you are tired, you do not see as well, you are less alert, and it takes you more time to make decisions, which are not always good ones.
A tired driver takes an extra moment to brake for a car that stops short, and that moment is the crash.
It takes you more time to make decisions and you do not always make good decisions.
On a long trip, take a break about every two hours, or whenever you need one: walk around, get fresh air, and have something to drink.
Hours of steady road lull a driver, and a few minutes out of the car can keep them awake.
Stop every two hours or so, or when you need to.
Before a long trip, eat lightly and do not eat a large meal, because some people get sleepy after a big meal.
A heavy lunch before a long drive can leave a driver nodding off an hour down the road.
Do not eat a large meal before you leave.
Do not start a trip when you are already tired; get a normal night's sleep and plan to leave when you are rested.
A driver who starts out tired only gets more tired with every mile.
Do not leave on a trip if you are already tired.
Try not to drive late at night when you are normally asleep, because your body thinks it is time to sleep and will try to.
At 2 a.m. a driver's body is set to sleep, and it can shut their eyes at highway speed.
Try not to drive late at night when you are normally asleep.
Never drive if you are sleepy: it is better to stop and sleep for a few hours, or switch with another driver, than to take a chance you will stay awake.
A driver who bets on staying awake can lose that bet in a single second.
It is better to stop and sleep for a few hours than to take a chance you will stay awake.
On the test
How does being tired affect your decisions behind the wheel?
You take longer and decide less well. A tired driver takes an extra moment to brake for a car that stops short, and that moment is the crash. Montana Driver Manual, p.71: “It takes you more time to make decisions and you do not always make good decisions.”
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.
