The NRP stopped about 100 vehicles while conducting a R.I.D.E. program in Port Colborne.
Officers were in the Quarry Road and Pleasant Beach Road area from 5:00 p.m. to 11:00 p.m. Friday night.
They conducted five roadside tests in the end but no further details have been released.
Lots of people have been hanging around the Quarry and Pleasant Beach area lately, so the NRP is stepping up its patrols and R.I.D.E. programs in response.
