Blood alcohol effects chart — Alaska Permit Test
Blood alcohol effects chart on the Alaska permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
The manual's chart shows judgment and inhibitions affected at a blood alcohol level of 0.02%.
Judgment is touched at the very lowest level shown, so even one drink can change the choices a driver makes.
0.02% —Judgement — Inhibitions
The manual's chart shows reaction and coordination affected at a blood alcohol level of 0.06%.
Slower reactions mean a longer gap between seeing danger and braking, and that gap is where crashes happen.
0.06% — Reaction —Coordination
The manual's chart shows serious deterioration in driving performance at a blood alcohol level of 0.08%.
By this level driving itself falls apart, not just one skill, which is why the law draws a hard line there.
0.08% — Serious deterioration in driving performance
The manual's chart shows vision, speech and balance affected at a blood alcohol level of 0.10%.
A driver who cannot see clearly or keep balance cannot judge distances or hold a lane.
0.10% — Vision — Speech — Balance
The manual's chart shows walking and standing affected at a blood alcohol level of 0.16%.
Someone who cannot walk or stand steadily has lost far more control than driving a car demands.
0.16% — Walking — Standing
The manual's chart shows a person unconscious, with possible coma and on the verge of death, at a blood alcohol level of 0.40%.
Alcohol at this level can kill without any crash at all, which shows how strong a drug it is.
0.40% — Unconscious — Possible coma and on verge of death
On the test
At what blood alcohol level does the manual's chart first show judgment and inhibitions affected?
0.02%. Judgment is touched at the very lowest level shown, so even one drink can change the choices a driver makes. Alaska Driver Manual, p.23: “0.02% —Judgement — Inhibitions”
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.
