Toronto police participate in pilot project to test drivers for drug impairment.

The pilot project, which runs until the spring of 2017, will be carried out by members of the Toronto Police Service’s traffic unit, Ontario Provincial Police and the RCMP.

Toronto police will begin testing roadside screening devices for drug-impaired drivers as part of a pilot project that begins Monday.

How well the officers are able to use the devices in inclement weather conditions, such as rain and snow, and how the devices operate at night is the purpose of the project.
