Although possession of marihuana will be legal July 1, driving high in Alberta will be still be illegal if a bill introduced in the legislature Tuesday is passed.

Transportation Minister Brian Mason says the bill outlines the rules that police and the courts will use in determining impairment.

"These proposed amendments to Alberta's Traffic Safety Act are the Province's response to changes proposed by the Federal Government to impaired driving laws in the Criminal Code as part of Bill C-46," Mason says. "I've said it before and it bears repeating that impaired driving is the leading cause of criminal death and injury in Canada."

Between 2006 and 2015, 1001 people in Alberta died as a result of alcohol or drug impaired driving and over 15,000 were injured.

The new legislation expands the zero tolerance program for Graduated Drivers Licenses, something MADD was happy to see.

The Chair of the national board of directors of Mothers Against Drunk Driving, Brenda Johnson, says  the province is leading the way with this legislation.

"MADD Canada certainly supports the legislation that was announced today and we want to share our appreciation to this government for the hard work, we know it's not an easy task to bring in new impaired driving legislation," Johnson says.

A 90-day, fixed-term licence suspension for drivers found over federal criminal limits. Following the 90-day suspension, drivers would have the option to participate in a one-year ignition interlock program to have their licence reinstated. If they decide not to participate in the program, their licence would remain suspended for that year.

In addition to provincial sanctions, impaired driving can lead to criminal charges, which could ultimately result in additional suspension terms and interlock participation, fines and possible jail time.

If passed, the amendment related to 90-day licence suspension followed by one year of interlock would be implemented by Feb. 1, 2018. The cannabis-related amendments would be proclaimed and become law when the federal government has its legislation in place.
