I moved to TO over 15 years ago and was amazed at the number of people who made 3 point turns, and did so very badly. I was also amazed at how other drivers usually waited patiently while they tried! In most other cities you would not dare to make these turns, not because you might get a ticket but because you might get killed. Are they really legal in Toronto?
A U-turn, whether you perform it in a loop or as a three point turn, is legal unless it is signed 'no U turns' and the street is (of course) two way.
