Who’s At Fault in Caution Light Crashes?

Canada’s dreaded amber light is the source of numerous intersection crashes, resulting in untold insurance claims. Because of this, be especially vigilant when turning left against yellow caution lights at intersections. Although the outcome of a given case will be determined based upon the facts that are unique to that case, a driver making a left-hand turn will generally not be able to rely on an assumption that the other driver will stop for the yellow light.
Fault for the resulting collision will likely be found in such cases on the part of the left-turning driver. 
Drivers have a legal duty to stop for a yellow light, but only if they can do so safely. Otherwise, they are allowed to proceed through the intersection with caution.
The Highway Traffic Act states that a left-turning driver must ensure the turn can be safely made, so it is the responsibility of that driver to make sure it is safe to proceed through the intersection. 
Some drivers attempting to make a left turn on a yellow light may assume that an approaching vehicle will stop; however, this assumption does not lessen or negate liability for left-hand turning drivers in the event of a collision.
