Impaired driving law changes
Changes to Alberta’s alcohol- and drug-impaired driving offences and sanctions come into effect April 9, 2018.
Alberta is updating impaired driving laws to prepare for the legalization of cannabis and to set time limits for licence suspensions.
The following changes come into effect on April 9, 2018:
zero tolerance for cannabis or illegal drugs in the blood stream of GDL drivers, in addition to alcohol
immediate 90-day licence suspension for impaired drivers, followed by participation in a one-year ignition interlock program
Proposed new blood drug concentration limits will come into effect later this year after federal legislation to legalize cannabis and update the Criminal Code receives Royal Assent.
Zero tolerance program
Drivers under the Graduated Driver Licensing (GDL) program found to have any amount of cannabis or illegal drugs in their blood are now subject to the same provincial sanctions that apply to alcohol, including:
immediate 30-day licence suspension
immediate 7-day vehicle seizure
must remain in GDL program for 2 years, with one year of suspension-free driving time
GDL drivers who meet the requirements for criminal level impaired driving will be subject to any and all provincial sanctions and criminal penalties that apply.
Licence suspension program
All drivers who are reasonably believed to be criminally impaired, whether through alcohol, drugs or refusing to provide a breath or fluid sample, will be subject to the following sanctions:
immediate 90-day licence suspension
immediate 3-day vehicle seizure (7 day for a second and subsequent occurrence)
mandatory remedial education
one-year participation in a provincial ignition interlock program
Drivers who do not participate in the ignition interlock program will remain suspended for the year.
These sanctions are in addition to criminal charges and any and all penalties imposed by the court. There are no changes to the post-conviction requirements.
Blood concentration limits
Changes to federal impaired driving laws will come into effect after Bill C-46 receives Royal Assent later this year.
Proposed changes include:
new drug-impaired driving offences with specified blood-drug concentration (BDC) limits for several illicit drugs and tetrahydrocannabinol (THC), the main mind-altering ingredient found in cannabis
updated penalties for impaired driving
Detailed information will be provided before these changes come into force.
Drug-impaired driving is already a criminal offence. What will change is the blood-drug concentration limits for cannabis and cannabis/alcohol combination. This is similar to the existing .08 per cent blood alcohol concentration for criminal-level alcohol-impaired driving.
Table 1: Proposed blood-drug concentration limits
Blood concentration level Federal criminal penalty *
2 nanograms (ng) per milliletre (ml)
but less than 5 ng/ml THC Maximum $1,000 fine (summary conviction)
5 ng/ml or more THC **
2.5 ng/ml or more THC combined
with 50 mg/100ml or more alcohol
1st offence: Minimum $1,000 fine
2nd offence: Mandatory 30 days imprisonment
3rd offence: Mandatory 120 days imprisonment
* Penalties are more serious for drivers who have high levels of impairment or who injure or kill others while driving impaired, and those who are repeat offenders.
** This section also includes penalties for exceeding any blood drug concentration as established in federal regulations. THC is just the first. Limits for illegal drugs may follow.
Information on other changes to federal impaired driving laws is available on the Government of Canada website.
Impaired driving stats
Impaired driving is impaired driving, no matter what the substance may be.
Research from the Canadian Centre of Substance Use and Addiction shows that, on average, cannabis use doubles the risk of being involved in a collision.
They found that driving skills are negatively affected after consuming cannabis, including the reduced ability to:
track moving objects
respond to more than one source of information
respond to sudden changes in driving environment
The risk of collision greatly increases if cannabis is consumed with alcohol. Mixing alcohol and drugs such as cannabis significantly increases impairment. In Alberta:
24.1% of all road fatalities involved a driver who tested positive for both alcohol and drugs in 2013
389 people were killed and 5,969 people injured in alcohol-related collisions between 2013 and 2015
Winter Driving Tips
Winter driving can sometimes be a daunting task, especially when conditions are snowy or icy. If road conditions are dangerous, consider making alternate travel arrangements or postponing your trip until conditions improve.
Follow these steps to keep yourself safe and collision free during the next few blustery winter months.
Step 1: Make sure that your vehicle is prepared for winter driving.
Winter tires are a good option, as they will provide greater traction under snowy or icy conditions.
Keep a snow brush/scraper in your car, along with possible emergency items such as a lightweight shovel, battery jumper cables, and a flashlight.
Make sure that mirrors, all windows, and the top of your vehicle, are free of snow or frost before getting onto the road.
Step 2: Drive smoothly and slowly
Don’t make any abrupt turns or stops when driving. Doing so will often cause your vehicle to lose control and skid.
Driving too quickly is the main cause of winter collisions. Be sure to drive slowly and carefully on snow and ice covered roads.
Step 3: Don’t tailgate.
Tailgating becomes much worse in winter weather. Stopping takes much longer on snowy and icy roads than on dry pavement, so be sure to leave enough room between your vehicle and the one in front of you.
Step 4: Brake before making turns.
Brake slowly to reduce speed before entering turns. Once you have rounded the corner you can accelerate again.
Step 5: Learn how to control skids.
When skidding, you actually need to go against your natural instincts and turn into the skid and accelerate. Doing so transfers your vehicle’s weight from the front to the rear and often helps vehicles to regain control.
Step 6: Lights On.
Turn on your lights to increase your visibility to other motorists.
Step 7: No Cruise Control.
Never use cruise control if conditions are snowy, icy, or wet, because if your car hydroplanes, your car will try to accelerate and you may lose control of your vehicle.
Step 8: Don’t “pump” the brakes.
If your vehicle is equipped with an anti-lock breaking system (ABS), do not “pump” the brakes. Apply constant pressure and let the system do its work.
Step 9: Pay attention.
Manoeuvres are more difficult to make in the snow. Be sure to anticipate what your next move is going to be to give yourself lots of room for turns and stopping.
