A vehicle is positioned in a controlled intersection waiting to turn left from a two-way road. The light turns amber, and the driver waits for traffic to legally pass through the intersection. Assuming the rest of the traffic will stop, the vehicle proceeds with the left turn. However, another vehicle proceeds through the "late" amber light and crashes into the vehicle turning left.
In Ontario, the Highway Traffic Act states the following:
Every driver approaching a traffic control signal showing a circular amber indication and facing the indication shall stop his or her vehicle if he or she can do so safely, otherwise he or she may proceed with caution. R.S.O. 1990, c. H.8, s. 144 (15)
The driver or operator of a vehicle upon a highway before turning to the left or right at any intersection or into a private road or driveway or from one lane for traffic to another lane for traffic or to leave the roadway shall first see that the movement can be made in safety ... R.S.O. 1990, c. H.8, s. 142 (1)
In a BC ruling, Domil v. Cheung, the supreme court noted the following:
 In Kokkinis, Madam Justice Newbury said the following about an accident occurring at another busy intersection in Vancouver (at para. 10):
…An amber light is not, as the current witticism suggests, a signal to accelerate or to pass traffic that is slowing to a stop. Indeed, as Mr. Justice Esson noted in Uyuyama, in a busy city like Vancouver and at a busy intersection like 25th and Granville, an amber is likely the only time one can complete a left turn. Drivers approaching intersections must expect that this will be occurring. Putting a burden on a left-turning driver to wait until he or she sees that all approaching drivers have stopped would, in my view, bring traffic to a standstill. We should not endorse such a result.
 Madam Justice Newbury’s observations apply with equal force to the busy intersection of Main Street and King Edward.
In this case, the driver "running" the amber light was found to be 100% at fault. I cannot find any similar rulings in Ontario, however.
Would a similar ruling be made in Ontario, i.e. are drivers allowed to assume vehicles will stop at an amber light when it is safe to do so, and what rulings have been made on similar scenarios in the past?
