Drinking and driving — Connecticut Permit Test

Drinking and driving on the Connecticut permit test — 8 rules, each with the reason behind it and a question on it while it is fresh.

The rules

Alcohol is involved in more than 40 percent of the traffic crashes in which someone is killed.

It is the largest single factor in fatal crashes, which is why the penalties around it are the heaviest.

Connecticut Driver's Manual, p.33

No one can drink alcohol and drive safely, however many years they have been driving.

Experience does not protect against alcohol, because what alcohol takes is the judgment experience runs on.

No one can drink alcohol and drive safely, even if they have been driving for many years.
Connecticut Driver's Manual, p.33

Alcohol affects the areas of your brain that control judgment and skill, and you do not know you have had too much until it is too late.

Judgment is the tool you would use to notice the problem, and it is the first thing alcohol takes away.

Alcohol affects those areas of your brain that control judgment and skill.
Connecticut Driver's Manual, p.33

Alcohol slows your reflexes and reaction time, reduces your ability to see clearly, and makes you less alert.

Every one of those is something driving depends on, and they go together rather than one at a time.

Alcohol slows your reflexes and reaction time, reduces your ability to see clearly, and makes you less alert.
Connecticut Driver's Manual, p.33

In Connecticut, people under 21 years old could be considered impaired after having only one drink of alcohol.

A younger driver has less experience to spare and less tolerance, so the state sets the bar where one drink reaches it.

Connecticut Driver's Manual, p.33

One alcohol drink is 1.5 ounces of 80-proof liquor, 12 ounces of beer, or a 5 ounce glass of wine.

A drink is a measure, not a glass. Specialty drinks can hold several of them at once.

12 oz. of beer (a regular size can, bottle, mug, or glass), or a 5 oz. glass of wine

There is no way to sober up quickly; coffee, fresh air, exercise and cold showers do not help, and time is the only thing that will sober you up.

Alcohol leaves the blood at its own rate. Everything else makes a drunk driver feel awake rather than be sober.

There is no way to sober up quickly. Coffee, fresh air, exercise, or cold showers will not help.
Connecticut Driver's Manual, p.33

Going out with two or more people and agreeing which of you will not drink lets the group rotate a designated driver.

The decision has to be made before anyone drinks, because judgment about it is the first thing to go.

Arrange to go with two or more persons and agree which one of you will not drink alcohol.

On the test

In what share of fatal traffic crashes is alcohol involved?

More than 40 percent. It is the largest single factor in fatal crashes, which is why the penalties around it are the heaviest. Connecticut Driver's Manual, p.33: “Alcohol is involved in more than 40 percent of the traffic crashes in which someone is killed.”

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.
