Operation Impact to target the "Big Four"

Expect to see plenty of OPP cruisers on the roads this weekend as the OPP kick off Operation Impact.

The latest blitz targets what police call 'The Big Four': aggressive driving, impaired driving, inattentive driving, and lack of seat belt use.

Officials say so far this year at least 156 deaths on OPP patrolled roads have been linked to these factors and 175 thousand charges have been laid.

Speeding, just one form of aggressive driving, contributed to 50 deaths alone.
