DUI in Ontario blow a warn

DUI – Blow a ‘Warn’ or over 0.05. What happens next?

  • What happens when the Police make you take a roadside breath test and the result comes back as a “Warn”?
  • First, some important context.
  • The Police will make you take a breath test if they suspect that you’ve consumed alcohol while driving or in the care or control of a vehicle.
  • At the roadside, you’ll be asked to blow into a device.
  • This device will come back with three possible results.
  • Pass, which means you’ve done nothing wrong.
  • Fail, which indicates that your blood alcohol concentration level is above 80.  
  • At this point, the Police will place you under arrest and will take you to the Police station to undergo further alcohol testing.
  • The third possible result is a “warn.”
  • That means that the device detected alcohol in your system above 50 but below 80, which would place you under arrest.
  • However, there are consequences of blowing in this “warn” range.
  • First, your driver’s license will be immediately suspended.
  • If this is the first time you’ve blown a “warn” result, then your license will be suspended for 3 days with a $250 fine.
  • On a second “warn” result, you’ll get a 7-day immediate suspension, a $350 fine, and you’ll be required to take an education or treatment program.
  • On a third “warn” result, you’ll get a 30-day immediate suspension, a \$450 fine, you’ll be required to take an education or treatment program, and you will have to get an Ignition Interlock installed for 6-months.
  • Once installed in your vehicle, you will need to blow into this device. And your car will only start if you have zero alcohol in your system.
  • And finally, you will have to pay a license reinstatement fee to get your license back after the suspension period.
  • You cannot drive during your license suspension period.
  • If you drive and get caught, you will face a charge under section 53(1) of the Highway Traffic Act of Ontario called, Driving While Under Suspension.
  • This is a serious charge that carries with it an automatic 6-month license suspension and a minimum fine of $1,000.
  • If you’ve previously been convicted of this charge in the past, in addition to the fines and the 6-month suspension, you will face up to 6 months in jail.
