Question 5036

You have held a class B driver's license for more than two years. What is your maximum permitted alcohol level?

  1. 0.15 milligrams of alcohol per liter of exhaled air.
  2. 0.25 milligrams of alcohol per liter of exhaled air.
  3. 0.3 grams of alcohol per liter of exhaled air.
Show answer and explanation

Correct answer: 0.25 milligrams of alcohol per liter of exhaled air.

After more than two years with your license, you are no longer a novice driver. If you are not driving a vehicle subject to a lower limit, such as a truck over 3,500 kg or a taxi, your limit is the general limit: 0.25 mg/l in breath or 0.5 g/l in blood. The limit of 0.15 mg/l applies to novice drivers, and 0.3 grams is a blood alcohol figure, not a breath alcohol figure.
