There are a number of reasons why your licence can be suspended. Driving under the influence of drugs or alcohol is among the most serious. If testing indicates you are impaired you can be charged. If you refuse to provide a breath or blood sample you can also be charged. It should be noted that prescription drugs and over-the-counter medications could also impair your ability to drive
While each province has its own laws governing traffic offences there are similarities when it comes to offences. Using Ontario’s Highway Traffic Act (HTA), as an example, your licence may also be suspended for the following reasons:
- Zero Blood-Alcohol Concentration (BAC) for novice and young drivers.
- Medical suspension.
- Discretionary HTA suspensions.
- Mandatory HTA suspensions.
- Administrative driver’s licence suspension (ADLS).
- "Warn-range" suspension.
- Novice-driver violations.
Demerit points are given for traffic violations and the accumulation of these points can also lead to a licence suspension. Each province has its own point system. Under Alberta’s Traffic Safety Act, for example, the most common issued violations and their demerit point values are as followed:
- Stunting: three points.
- Failure to report an accident: three points.
- Driving on the wrong side of the road: three points.
- Following too closely: four points.
- Speeding (more than 50 km over the limit): six points.
- Failure to yield right of way to a pedestrian: four points.
- Racing: six points.
- Leaving the scene of an accident: seven points.
Your licence may also be suspended if you have a medical condition that affects your ability to drive. British Columbia’s Motor Vehicle Act states doctors, nurse practitioners, psychologists and optometrists must report patients they believe may be medically unfit to drive. Other provinces and territories have similar provisions.
Provinces such as Ontario also impose a one-year suspension for Criminal Code offences, with a potential lifetime driving ban for subsequent offences.
Under the HTA, your licence will be suspended if you are convicted of any of the following offences under the Code:
- Driving or having care and control of a vehicle, including boats, when your BAC is more than 80 milligrams per 100 millilitres of blood (.08).
- Refusing to submit to a breath test for alcohol.
- Failing or refusing to provide a breath sample for roadside testing.
- Failing to remain at the scene of a collision.
- Dangerous driving.
- Causing death or bodily harm by criminal negligence.
- Failing to stop for police.
