When there’s a large vehicle in front of you, you can not see your traffic light. Or can you?
The typical intersection in the Vancouver area has another signal light on the left (and sometimes right) side of the intersection so that you can still see the light if there’s a larger vehicle blocking your view. This light is often the exact same light as the regular one; usually if it is a left turning light it has a sign with it (‘Left Turn Signal’)
In this example the signal light is most definitely RED!
What else can you do when driving to increase your visibility in this situation? Leave more space (following distance) in front of you, of course.
