How many points do you receive on your license for 15 mph over the limit and how much does your insurance go up if this is your first ticket after traffic school in California?

Should only be 1 point, but I don't know how much your insurance will rise. If you went to traffic school long enough ago, you can just pay up & do it again - I think it's 18 months between. My carrier doesn't raise my rates with only 1 point. Always go to school, and stay cool for a couple years between each ticket and there's no bad for you.
