Alcohol, DWI, and the Point System: 10 sample questions

Practice questionReviewedRules of the Road › Alcohol, DWI, and the Point System★★★★☆

Question 1. At what blood alcohol concentration (BAC) is a driver 21 or older considered impaired by law?

  1. ① 0.02
  2. ② 0.05
  3. ③ 0.08
  4. ④ 0.10
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ 0.08

Key point: Adult BAC limit: 0.08

A driver 21 or older can be convicted of Driving While Impaired with a BAC of 0.08 or more. A driver can also be convicted at a lower level if alcohol or drugs clearly impair driving.

Wrong choices

  • 0.02: 0.02 is lower than the adult limit; drivers under 21 may not have any alcohol at all.
  • 0.05: Crash risk rises at 0.05, but the legal limit is 0.08.
  • 0.10: The limit is 0.08, not 0.10.

  3. ③ Up to 0.08
  4. ④ None at all
▼ Show answer and explanation▲ Hide answer and explanation

Key point: Under 21: zero alcohol

A driver under 21 may not drive with any amount of alcohol or drugs in the body. A conviction brings a one-year license revocation.

Question 3. A driver charged with DWI refuses to take a chemical test. What happens to the license?

  1. ① A warning letter
  2. ② Nothing, because the test is voluntary
  3. ③ An immediate revocation of at least 30 days, plus a DMV revocation of at least 12 months
  4. ④ A 2-point penalty
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ An immediate revocation of at least 30 days, plus a DMV revocation of at least 12 months

Key point: Refusal: 30 days at once plus 12 months from DMV

Refusing a required test brings an immediate revocation for at least 30 days and an additional revocation of at least 12 months by the DMV. The refusal can also be used as evidence in court.

Wrong choices

  • Nothing, because the test is voluntary: By driving in North Carolina you have agreed to testing; refusal has penalties.
  • A warning letter: Refusal brings a revocation, not just a warning.
  • A 2-point penalty: The penalty is a revocation, not points.

  1. ① Permanent revocation
  2. ② 30-day revocation
  3. ③ Four-year revocation
  4. ④ One-year revocation
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ④ One-year revocation

Key point: First DWI conviction: one-year revocation

A first DWI conviction brings a mandatory one-year revocation. Penalties grow with each later conviction.

Wrong choices

  • 30-day revocation: 30 days is the immediate revocation after a test result of 0.08 or a refusal, before any conviction.
  • Four-year revocation: Four years is for a second conviction within three years of a prior offense.
  • Permanent revocation: Permanent revocation is for a third conviction with a prior one in the last five years, or a fourth.

Question 5. What is the only thing that sobers up a person who has been drinking?

  1. ① Black coffee
  2. ② Time
  3. ③ A big meal
  4. ④ A cold shower
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ② Time

Key point: Only time sobers you

Only time removes alcohol from the body. Coffee, a big meal, or a cold shower will not work. Plan a sober ride before you drink.

Wrong choices

  • Black coffee: Coffee may make you feel more awake, but you are still impaired.
  • A cold shower: A cold shower does not lower your BAC.
  • A big meal: Food does not remove alcohol already in your blood.

North Carolina's DWI laws forbid drinking any alcohol, including beer, while driving, and forbid carrying an open container of alcohol in the passenger area.

Wrong choices

  • Listening to the radio: Listening to the radio is legal, though it can distract you.
  • Carrying sealed groceries: Sealed groceries are not alcohol in an open container.

  • Points are doubled: Finishing the clinic lowers your points; it does not raise them.
  • Nothing changes: Finishing the clinic does change your record: three points come off.
