Driver's licence laws
Warn-range suspension

Drivers who register a blood alcohol concentration in the warn range of .05 to .08 pose an immediate danger to themselves and other road users. If caught driving in the “warn range,” you will receive an immediate driver’s licence suspension at the roadside:

  • For three days for a first occurrence
  • For seven days for a second occurrence and you must undergo a remedial alcohol education program
  • For 30 days for a third or subsequent occurrence in a five-year period, and you must undergo a remedial alcohol-treatment program and have an ignition interlock condition placed on your licence for six months. If you choose not to install an ignition interlock device, you must not drive until the condition is removed from your licence.

An administrative monetary penalty is also imposed on drivers suspended for registering in the warn range.
