Question 4101

What is the maximum permitted alcohol level for the driver of a school transport vehicle?

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

Correct answer: 0.15 milligrams per liter of exhaled air.

Anyone driving a school transport vehicle, like the bus in the image, must not exceed 0.15 mg/l in exhaled air, even if they have held their license for many years. The blood limit is 0.3 g/l, so 0.3 mg/l in exhaled air would be double the limit. The general limit of 0.25 mg/l does not apply to this type of transport.
