If you register a BAC from ___________ (known as the 'warn range') you will receive an immediate driver's licence suspension.

  1. .07 to .08
  2. .06 to .10
  3. .05 to .08 ✓
  4. .06 to .12

Answer: C. .05 to .08

The warn range is .05 to .08, and registering a blood-alcohol concentration in that range brings an immediate driver's licence suspension.

Why this is the answer

The handbook says the warn range is a blood-alcohol concentration of .05 to .08. It also says a driver caught in that range gets an immediate roadside licence suspension. The passage gives three days for a first occurrence and seven days for a second, with a remedial alcohol-education program and increased penalties after that. So the range that triggers the immediate suspension is .05 to .08, which matches the bank answer.

Why the other answers are wrong

Remember it

Remember the warn range as five-to-eight: .05 up to .08.
