Re: Amber Light
Intersections are a very likely place to have an accident. The flow of traffic is disrupted and people unwittingly or intentionally make bad decisions.
That said, I'm going against the developing grain just a little bit.
In my state, which uses photo-enforcement at some intersections, if your front tire (or tires) is across the white line of the intersection while the light is still yellow, you're ok. Even if the light turns red at the instant that your tires are completely across the line and into the intersection, you will get no ticket.
In the event you get stopped by Police in the same scenerio, then it's your word against his. Unless you happen to have your go-pro on and it shows indisputably that your tire was across the line before it turned red.
Our lights stay yellow for a good 3 or 4 seconds in the busier intersections. When I'm driving my work van, loaded down with weight, I sensibly use this knowledge to determine whether or not to come to a nose diving stop. Because like everyone here, occasionally I might be going 5 to 10 mph over the posted limit of 45, 50, or 65 mph. (You rarely, if ever, get stopped if you don't exceed the posted limit by more than 10mph)
When I'm riding my bike, I'm extra obedient about stopping at traffic signals. Cops watch for sportbikes even more than cars in my area, plus I like to set a good example for the cagers about us sportbike riders.
