Alcohol in the body — Louisiana Permit Test
Alcohol in the body on the Louisiana permit test — 5 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Once you drink, alcohol reaches your brain in about 20 minutes.
A drink starts to dull your thinking within minutes, so the danger begins long before you feel drunk.
It reaches your brain in about 20 minutes.
Alcohol is a depressant, not a stimulant; it slows the brain down.
Some people feel peppy after a drink, but that is only lost caution. The brain is being slowed, not sped up.
Alcohol is a depressant, not a stimulant.
Beer, wine and whiskey impair you alike: what matters is how much alcohol gets into your blood.
A can of beer is not a safe swap for a shot. Your body only counts the alcohol, not the kind of drink.
it doesn’t matter whether you drink beer, wine, whiskey or any other alcoholic beverage;
A small amount of alcohol on an empty stomach affects you faster than it would after you have eaten.
With no food to slow it down, alcohol rushes into the blood, so even a little hits hard.
A small amount on an empty stomach will affect you more rapidly than it would if you had recently eaten.
Black coffee, exercise or a cold shower will not sober you up; only time lets the liver get rid of alcohol.
Tricks that make you feel awake do not take alcohol out of your blood, so you are just as unsafe to drive.
Black coffee, exercise or a cold shower will not sober you up.
On the test
About how long does it take alcohol to reach your brain after you drink it?
About 20 minutes. A drink starts to dull your thinking within minutes, so the danger begins long before you feel drunk. Class D & E Driver's Guide, p.122: “It reaches your brain in about 20 minutes.”
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.
