I know about the law/rule of being able to run a red light, if you are turning right, in the US (if you do not endanger the traffic...)
By my knowledge, no such law excists in France, and for my job I drove a lot in France. If such a law would excist there, I would...
- first of all, have spend a lot of time, uselessly, at traffic signs...
- secondly, never dare to try it, knowing how the French drive...
On the other hand... if you run a red light, which is against the law (whether regularly enforced or not...), you should not bicker about the fine... you knew beforehand you were comitting a felony...
(btw... from Santiago to La Vega there is one traffic light... and when it is red, I'm prob the only moron stopping there, with cars honking angrily at me for doing so, and passing me left and right, and me fearing for my life every second of that red light... but I'm sure I would also be the only moron being fined for crossing it...
