3 points does affect your insurance

I got three points back in July for overtaking a bus on an uphill stretch. SP30 £60 and the points. Gutted

Today having received my car insurance quote for next year, I called in to tell them of the change (apparently I should have done this at the time?), an extra £45 on my policy this year, that's almost 12%!

I wonder if the police are working with the insurance companies to generate revenue, I'll be paying this penalty for the next 3/4 years.
