Surely if you go inbetween the front two cars they assume you are on a bike lol and that's what we do.....
We were told that was not the correct position as it could be assumed by the car drivers that you were being aggressive and wanted to "race" them from the lights.
To the best of my knowledge, it is illegal to filter to the front of the traffic. The first vehicle usually pulls right up to the white line, therefore if you were to filter through and pull in front, you will need to cross the white line on a red light (illegal positioning).If you were to filter through and stop in line with the two front vehicles, you are, in effect, making a third lane (illegal positioning).One other point is that when the lights change from red to red/amber, the first thing on your mind is usually to pull away quickly to clear the two vehicles either side of you, not allowing for the idiot thats just run a late red light in the other direction. I have my Bike Safe next weekend in Barry, I will try to get a clear definition of whats safe, and whats legal.
Well technically green means "proceed with caution".If you can leave a junction at a quick enough pace, while checking the vehicles on your left and right are not trying to out run you from the lights, and at the same time looking left and right at the as you pass through the junction checking for a red light jumper, emergency vehicle, or a stolen car being chased, then good luck to you... I know where I would prefer to wait...
