Have you tried asking your local authority about the reason for this change?A road near where I live has just has a continuous white line painted where there was none before. It's the only stretch where you can safely overtake.
The cynic in my believes that this is all a money making exercise.
Usually 2 doesn't affect insurance, though you should ring and tell insurance company about them.....
I got 2 pts about 3.5 years ago. Did not inform Insurance Co. Blow me, just after I got my null points back, I got caught a few months later. So back to square one. Have not informed Company and won't. If PC people feel up to it - then fine. I also don't inform them when having a bad day at the office, girls problems, whats on the box tonight problems, what shall I wear at so and so's do. Man born free but forever in chains.
