The Ontario Provincial Police will be out and about this Thanksgiving weekend keeping an eye on the roadways across the province.

Since October 1st 156 people have lost their lives in accidents so the OPP will be looking for what they call The Big Four.

These are the 4 leading causes of road fatalities.

Aggressive driving, alcohol and drug impairment, inattentive driving and the lack of a seat belt.

Nearly a third of those deaths can be attributed to speeding and aggressive driving.
