Is this really considered running a red light?

The argument can be made that it was my fault for following so closely behind the truck, in other words tailgating, to the point where I couldn’t see the red light.

Sorry if I made no sense, I shall decline in answering this question.

I say using the truck as an excuse for not seeing the light wouldn’t work.

We get tickets for running a yellow, $150 bucks, I think. I would think the car behind the semi was at fault. This is Alberta.
