Section 320.12 — Criminal Code: Recognition and declaration

It is recognized and declared that operating a conveyance is a privilege that is subject to certain limits in the interests of public safety that include licensing, the observance of rules and sobriety; the protection of society is well served by deterring persons from operating conveyances dangerously or while their ability to operate them is impaired by alcohol or a drug, because that conduct poses a threat to the life, health and safety of Canadians; the analysis of a sample of a person’s breath by means of an approved instrument produces reliable and accurate readings of blood alcohol concentration; and an evaluation conducted by an evaluating officer is a reliable method of determining whether a person’s ability to operate a conveyance is impaired by a drug or by a combination of alcohol and a drug.
