Most BC drivers who blow over the limit get an Immediate Roadside Prohibition. But police can also lay charges under the federal Criminal Code, especially after a crash, a high reading, a refusal or repeat offences. A criminal charge goes to court, and a conviction means a criminal record.
The main charges
- Impaired driving: your ability to drive was impaired to any degree by alcohol, drugs or both.
- Over 80: a blood alcohol concentration of 80 mg per 100 mL of blood or more within two hours of driving.
- Refusal: failing or refusing to comply with a lawful demand for a breath, blood or drug test sample.
- Drug-impaired driving: 5 ng or more of THC per mL of blood, or any detectable amount of certain drugs such as cocaine or methamphetamine, within two hours of driving.
Penalties on conviction
| Offence | First offence | Second offence | Third offence |
|---|---|---|---|
| Impaired / over 80 (BAC 80–119) | minimum $1,000 fine | minimum 30 days jail | minimum 120 days jail |
| Over 80 (BAC 120–159) | minimum $1,500 fine | minimum 30 days jail | minimum 120 days jail |
| Over 80 (BAC 160 or more) | minimum $2,000 fine | minimum 30 days jail | minimum 120 days jail |
| Refusal | minimum $2,000 fine | minimum 30 days jail | minimum 120 days jail |
The maximum penalty is 10 years. Impaired driving causing bodily harm carries up to 14 years, and causing death carries up to life imprisonment. A conviction also brings a court-ordered driving prohibition, and RoadSafetyBC can require the Responsible Driver Program and ignition interlock.
Having between 2 and 5 ng of THC per mL of blood is a lesser offence with a maximum fine of $1,000.
Two cases at once
A criminal charge and a provincial prohibition run separately. You might win an IRP review and still face the criminal case, or the reverse. Decisions in one can affect the other, which is why it pays to get advice early.
How these cases are defended
Defence lawyers look at the reason for the stop, the timing and wording of the breath or drug demands, your right to speak with a lawyer, how the testing was done and whether the evidence was properly disclosed. Charter breaches can lead to evidence being excluded.
