On January 30, 2018, a concerned citizen called the Central Saanich Police to report a possible impaired driver travelling northbound on Hwy 17. The witness observed the vehicle driving at different speeds, drifting in the lane, signalling incorrectly and almost colliding with the guardrail then another vehicle. The vehicle was quickly located and pulled over by police.  In speaking with the driver, the officer noticed the driver’s physical and verbal responses were quite slow.  The driver indicated that she was taking prescription medication for pain. The officer performed a Standard Field Sobriety Test and determined that the driver’s ability to operate a motor vehicle was impaired by the drug.  A 24-hour roadside prohibition was served and the vehicle was towed.  While the driver did not appear to intentionally drive while impaired, this incident serves as a good reminder to all of us that we need to be aware of what might affect our ability to drive, even if the substance taken is legal.  Drive safe.
