Here's a video of what it's like to answer an Urgence Santé call with lights flashing and siren blaring.It's pretty scary.
Count how many idiot drivers react badly or not at all to the siren.
I wonder how many accidents they get into a year.
I once saw a senior citizen plow his fifteen year-old Cadillac into an ambulance on Van Horne & MacDonald. I stopped to be a witness for the ambulance driver. When the driver asked the old guy if he saw the lights and heard the siren, the senior complained that he had the right of way, since his light was green. Arghh....
