It is against the law to enter an intersection when:

The intersection is marked with a ‘No Entry’ sign.
The light is yellow and you can stop safely.
You can’t get all the way across before the light turns red.
The light is flashing yellow and you didn’t stop first.
Explanation

It is illegal to enter an intersection when you can't get all the way across before the light turns red. This is because entering the intersection when there is not enough room to make it all the way across will block traffic. This can cause gridlock on other streets, and even if you have a green light, you can be cited for blocking an intersection.
