The US has the same thing the problem is it's not always followed. Many drivers don't view the amber/yellow light as "I should stop now" but rather view it as "I better speed up so I don't get stuck at the red light". There's also been much accusation (though I have no links handy to provide as proof) of townships implementing red-light cameras and then changing, without warning, the duration of the amber light to be shorter. Keeping in mind that the law states that you cannot be inside the intersection when the light is red, if you entered it while the light was green or amber is irrelevant [Edit - It's been correctly pointed out below that this law may vary from state to state].

That's not the law in California. It is perfectly legal to be within an intersection when the light turns red. It's only illegal to enter an intersection while the light is red. Source 1: California Driver Handbook http://apps.dmv.ca.gov/pubs/hdbk/traff_lgts_sgns.htm http://apps.dmv.ca.gov/pubs/hdbk/traff_lgts_sgns.htm - - - Solid Yellow – A yellow signal light means "CAUTION." The red signal is about to appear. When you see the yellow light, stop if you can do so safely. If you cannot stop safely, cross the intersection cautiously. - - - The "stop if you can do so safely" wording is safety advice, and sound advice too. But it's not a statement of law.

(a) A driver facing a steady circular yellow or yellow arrow signal is, by that signal, warned that the related green movement is ending or that a red indication will be shown immediately thereafter. 21453. (a) A driver facing a steady circular red signal alone shall stop at a marked limit line, but if none, before entering the crosswalk on the near side of the intersection or, if none, then before entering the intersection, and shall remain stopped until an indication to proceed is shown, except as provided in subdivision (b). - - - Note that the yellow light is described only as a warning, with no mention of it being illegal to enter the intersection while the light is yellow. And there is no mention of it being illegal to be inside the intersection when the light turns red, only that you can't enter on a red light. I can't speak for other states, but I suspect that the laws in many of them are similar.

  Thank you for the correction. I'm in NJ and remember my instructor going out of his way to mention that it was illegal to be in the intersection when red. However upon investigation I can't actually find anything to back this up now. It would appear I may have been operating under false information all these years.

    I guess that's not an unreasonable thing for a driving instructor to say, since even if it's not quite true, it does no harm to believe it and may well help someone err on the side of safety. I had a similar misunderstanding myself until recently. I'd read the wording in the driver handbook and thought that the bit about "if you can stop safely" was the actual law rather than safety advice. It was much later that I got curious and looked into it a little further.

      It's not quite as clear as that, the California Driver's Handbook states: "Do not enter the intersection if you cannot get completely across before the light turns red. If you block the intersection, you can be cited." [0] You might think this is only referencing situations where you are stopped in the intersection (i.e. blocking it) but there is no reference to speed here. There's a question on the test: [1] Q: It is against the law to enter an intersection when: A 1: You can't get all the way across before the light turns red A 2: The light is flashing yellow and you didn't stop first A 3: The light is yellow and you can stop safely The correct answer is 1. So, when viewed by a normal person, you may assume that this only applies if you're forced to stop in the intersection (and therefore block it), but neither the driver's handbook, nor the test itself (sorry my link is just an unofficial practice test, but it's on the real thing too) make any reference to speed. Therefore I think it's absolutely reasonable for your "instructor going out of his way to mention that it was illegal to be in the intersection when red" [GP] I haven't looked up the actual law to see if the wording makes it OK to be in an intersection with the light red, providing you entered legally (yellow/green) and have a clear exit path - but I'm guessing it does not.
