It's not risky to go through an intersection when the light is yellow. If your light is yellow, the cross light is red. Proceeding through a yellow is no riskier than a green. Traffic lights originally only had red and green. Municipalities added yellow specifically to prevent brake-slamming stops that led to crashes. Slamming the brakes on yellow is contrary to its purpose.
