SP codes refer to speeding offences/convictions. SP30 is the code for exceeding the statutory speed limit on a public road and it is one of the most common offences seen by police. An increase in speed cameras and traffic police is aimed at reducing this type of offence.
The penalty for speeding is a minimum fine of £100 and between 3 and 6 points added to your license, depending on the nature of the offence. If it is your first speeding offence, you might be given an option to attend a speed awareness course. If the level of speeding is excessive you may also be faced with a driving ban.
