Pulling out of a shop's car park onto the road, you make an approaching driver brake hard. Nothing is hit. Is there an offence with a set fine for that?

Correct answer: A. Yes — failing to yield when entering from a driveway carries an $85 set fine, whether or not anything is hit

Yes. Schedule 43 lists "Fail to yield from driveway" against Highway Traffic Act section 139(1) at a set fine of $85.00 outside a community safety zone. The section requires a driver "entering a highway from a private road or driveway" to yield to all traffic "approaching on the highway so closely that to enter would constitute an immediate hazard", and making an approaching driver brake hard is the everyday evidence that you did not. No collision is needed for the offence to be complete — the wrong was in the entering, not in the outcome. It is worth setting alongside the identically priced offences for failing to yield after stopping at a stop sign or a flashing red: Ontario prices most everyday yielding failures the same, and it is the demerit points and the insurance consequences that separate them.
