There have been two fatal accidents at opposite ends of Montreal in the past 12 hours.

Around 8 o'clock last evening, on the 20 westbound near Les Coteaux, in the Monteregie, three cars collided. One of the drivers, a 40-year-old man from the nearby town of Riviere-Beaudette was killed. Another driver was badly hurt. The third was not injured and is suspected of driving drunk.

"He was arrested for DUI," says Gregory Gomez del Prado of the Surete du Quebec. "He will appear in court likely today."

The 36-year-old suspect was also driving with a 4-year-old girl who was not hurt.

Meanwhile, around 1 a.m. Friday on the 20 eastbound near Saint-Hyacinthe, an 18-year-old driver got into an accident with another car and fled the scene. But she took off in the opposite direction and collided with two trucks. She did not survive. Police say they are studying different theories, but it's possible the driver was drunk, or suicidal. 

The 20 eastbound near Saint-Hyacinthe was closed for several hours Friday morning causing problems for the morning rush hour as investigators studied the scene.
