A YouTube video showing a confrontation between a female motorist and a truck driver has gone viral, reaching almost 400,000 hits in less than three days.

The video was captured from a camera on the dashboard of a 12-wheel dump truck as it drove down a street in Hampstead, a residential neighbourhood in Montreal.

A Montreal trucking company is now showing the video to its employees for training purposes. Montreal police said if you find yourself in an argument with another motorist, you should ignore the driver. If they're aggressive, police advise that you take down the licence plate number and a description of the vehicle. And, they said you should never get out of your own vehicle.
