it is a bit harsh but im afraid im going to be honest now. double white lines are there for a reason and that is to stop people overtaking. you took the risk of having your car taken when you decided to overtake on double whites and then not even stopping?? they may have let you off with a warning if you had at least stopped. my boyfriend has found that out many times. also,if you have been stopped for this 5 times i would of thought you had learned by your mistake. sorry if this post upsets anyone but that is how i see it.
