Question 7792

If a novice driver has a breath alcohol level of 0.20 milligrams per liter, will the traffic officer give them a second breathalyzer test?

  1. No, for that the level must be higher than 0.25 milligrams per liter.
  2. Yes, for greater certainty and as a cross-check.
  3. Only if the driver is directly involved in a traffic accident.
Show answer and explanation

Correct answer: Yes, for greater certainty and as a cross-check.

Yes. An adult novice driver must not exceed 0.15 mg/l, so 0.20 mg/l is already a positive result, even though it is below the general limit of 0.25. The officer gives the driver a second breath test for greater certainty, at least 10 minutes later, whether or not there has been an accident.
