Lambton OPP say some drivers are still not getting it.
On Friday night at 8:30 p.m. and 10:30 p.m. OPP were performing traffic enforcement duties on London Line and on Highway 402 in Plympton-Wyoming.
They say two drivers were clocked travelling in excess of 50 kilometres per hour over the posted speed limit.
The 21 and 26-year-old males were charged with stunt driving, excessive speed, and had their drivers' licences and motor vehicles seized for seven days.
They must also appear for a mandatory court date to address the charges.
