The Checkstop Program allows police services to detect impaired drivers and share the dangers of impaired driving.


Simple. Throughout the year, police set up check points on Alberta's roads to stop drivers and check for signs of impairment. The locations change often and drivers or motorcyclists can be stopped at random.

If police believe that a driver is impaired by drugs or alcohol, they can require the driver to take a roadside breath test or a Standardized Field Sobriety Test (SFST). A roadside breath test gives officers a measure of the drivers' blood alcohol level. An SFST checks for signs of impairment by examining the driver's eyes, walking ability, and balance.

If the tests suggests impairment, a further Drug Recognition Evaluation and blood sample may be administered to confirm impairment. If impairment is proven for drugs, alcohol or their combination, charges can be laid and the driver's licence suspended. If drivers refuse to take a breath test or the SFST, charges can be laid and their licence can be suspended.
