The national blood alcohol limit is 0.08%. If you are found driving with a blood alcohol content of 0.08% or above, you can be charged under the Criminal Code. However, British Columbia has established a more stringent standard. In British Columbia, if you are found driving with a blood alcohol content of over 0.05%, you can be charged under the British Columbia Motor Vehicle Act. Under both the Criminal Code and the Motor Vehicle Act, you can also be charged for refusing a test for alcohol upon the request of an officer. Penalties for violating national or provincial laws can be severe, including loss of licence, vehicle impoundment, fines, and even jail.
