Have you ever accidentally driven down a one way street? It happens, with so many one ways in Montreal, accidents can happen. But chances are you were smart enough to realize your mistake immediately and turned around before anything bad happened.
Well I have good news for your my friend, at least you were stupid enough to drive full speed down the wrong side of a highway. Perhaps you were clued in by the fact there's a huge yellow double solid line in the middle of the road or maybe you noticed the cars headed straight towards you.
Unfortunately this driver wasn't bright enough to notice these clues which resulted in a pretty scary drive down the wrong side of the highway.
