Fatigue and driving — New Mexico Permit Test
Fatigue and driving on the New Mexico 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 you take more time to make decisions.
A tired brain is slow to notice a braking car and slow to choose what to do about it.
You do not see as well, nor are you as alert.
Do not leave on a trip if you are already tired; plan to leave when you are rested.
Starting a long drive tired means the worst of the sleepiness hits you out on the road.
Do not leave on a trip if you are already tired.
Before a long trip, avoid any medicine that can make you drowsy.
Pills that make you sleepy pile on top of the tiredness a long drive already brings.
Do not take any medicine that can make you drowsy.
Eat lightly before a long drive; do not eat a large meal before you leave.
Some people get sleepy after a big meal, and sleepy is dangerous behind the wheel.
Do not eat a large meal before you leave.
On a long trip, stop for a break about every hour or so, or whenever you need to.
A short walk and fresh air wake you up before tiredness turns into a crash.
Stop every hour or so or when you need to.
Never drive when you are sleepy; it is better to stop and sleep for a few hours than to try to stay awake.
You cannot tell when you will doze off, and a second asleep can put you off the road.
It is better to stop and sleep for a few hours than to take a chance thinking you can stay awake.
On the test
How does being tired affect your driving?
You see less well and decide more slowly. A tired brain is slow to notice a braking car and slow to choose what to do about it. New Mexico Driver Manual, p.28: “You do not see as well, nor are you as alert.”
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.
