Ontario Provincial Police (OPP) were out on Friday, citing two drivers who allegedly violated two of the so-called "big four" infractions.
The incidents occurred within about three hours.
The first was a few minutes before 4 p.m. in Lakeshore.
Officers spotted a vehicle being driven at excessive speed and conducted a traffic stop on Rourke Line.
The 29-year-old driver from Belle River was charged with stunt driving.
The second incident took place just after 7 p.m. on Point Pelee Drive in Leamington.
OPP officers responded to a complaint from wardens at Point Pelee National Park about a suspected impaired driver.
A 35-year-old LaSalle man is charged with impaired driving and driving with excessive blood-alcohol concentration.
Both drivers now have their licences suspended for 90 days, and their vehicles impounded for seven days.
The charges have not been proven in court.
