You are first in line to turn left at a red light, with a car facing you also stopped at its red. The instant the lights go green you launch your turn to get across before the oncoming car can move. What have you just done?

Correct answer: D. Committed a stunt — the regulation specifically names beating the oncoming car off a green as stunt driving

Committed a stunt, as Ontario defines it. O. Reg. 455/07 s.3 paragraph 8(iv) names this specific manoeuvre: a left turn made where the driver was stopped at a red, at least one vehicle facing the opposite direction was similarly stopped at a red, and the driver "executes the left turn immediately before or after the system shows only a circular green indication in both directions and in a manner that indicates an intention to complete or attempt to complete the left turn before the vehicle facing the opposite direction is able to proceed straight through the intersection." Racing the oncoming car off the line is not a grey area or a minor turning offence — it sits in the same regulation as street racing, and it is treated the same way.
