Two men are facing stunt driving charges according to Lennox and Addington OPP.
Officers stopped a vehicle on Friday morning around 1:20 a.m. heading east on the 401. The 19-year-old from New Westminster, British Columbia was clocked doing 183km/h.
Later that night, just after 10 p.m., officers stopped a 36-year-old man from Toronto after he was spotted driving 173 km/h on the eastbound 401.
Both men will appear in court next month.
Their licences were suspended for seven days and their vehicles impounded as well.
