It's a scary scene you never want to see on the highway. In this dash cam footage from Ottawa, Ontario, you can see a white SUV swerving across lanes on the highway. The SUV hits the median and guardrail, as it continues down the road. Thankfully, the driver of the dash cam vehicle was able to call the police and follow the SUV to its driver's workplace. That's when he says the police showed up. The Ottawa Police did confirm that a call came in for a possible impaired driver, and the driver of the SUV was arrested and charged.
