What is the law to apply when traffic at an intersection is governed by traffic control signals?

In my opinion, the law to be applied in the present circumstances, that is, when traffic at an intersection is governed by traffic control signals, is correctly set forth in the judgment of Des Brisay C.J.B.C. in Wong v. West, supra, when he said at p. 528: In my view, having the green light with him, travelling on a six-lane marked street he was entitled to proceed as he did and should not have been found negligent. He owed no duty to traffic entering the intersection in disobedience to the lights, beyond a duty that, if he in fact saw such traffic, he ought to take all reasonable steps to avoid a collision.
