Your licence will automatically be revoked if you build up 6 points or more within them two years.
If you have been done for speeding and recieve a ''fixed penalty notice'' from them, providing your not innocent its best to except the penalty notice, it will probably be 3 points and a �60 fine, if you contest this, and it goes to court, you could finish up getting more points, a bigger fine & court cost.
Ps, anyone who says they haven'y gone above the speed limit be it 5mph or 70 mph, is lying.
