Officers set up radar enforcement on Sept. 27 in the area of Montee Principale. At about 11 a.m., they saw a 1994 Toyota Camry driving 30 km/h over the posted speed limit.
The vehicle was eventually stopped and the woman driver showed obvious signs of impairment, said police. She was arrested and taken to police headquarters for breath samples.
The driver refused to provide samples, as required by law. When officers searched her, they found her to be in possession of marijuana, police allege.
In addition to her impaired charge, the woman faces charges of failing to provide breath samples and possession of marijuana. She was issued a 90-day licence suspension and had her vehicle impounded for seven days.
