THE TECHNOLOGY

The three devices being tested have not been approved for use in Canada, but will help officials set standards for the roadside tests that will be used here. Once the rules are finalized, manufacturers can submit their devices for testing. The ones that are green-lighted can be purchased by police agencies. The RCMP would not provide a time frame or budget for the purchase of the devices. In the meantime, police will rely on standard sobriety tests — such as touching your nose with your fingers — if they suspect someone is driving under the influence of pot.
