How long will the penalty points on my licence remain valid?
For 'totting-up' purposes on your licence, penalty points are effective for 3 years from the date of the offence. On application and payment of a fee, DVLA will issue a replacement driving licence without the points after a further year has passed.
The points remain "active" (for totting up purposes) for three years from the date of the offence, but it is four years before you can ask to have them removed.
