SP50 : exceeding speed limit on a motorway
Checked 17 July 2026 · How we check our figures
What it means
SP50 is the motorway's own speeding code, split from SP30 by venue rather than by anything the driver did differently. The split matters in two places: the court's fine ceiling is higher on a motorway, and enforcement runs through variable limits on the gantries, where the displayed number is the limit in force for that stretch and that moment. To the record and the insurer's question it reads as one more SP entry.
Points and how long it stays
3 to 6 points.
On the licence for 4 years from the date of the offence.
The SP codes split speeding by cause, not by consequence: SP30 for the ordinary road, SP50 for the motorway, SP10, SP20 and SP40 where the vehicle or what it tows carries a limit below the signs. Everything else is shared. The fixed penalty route is always 3 points (gov.uk, checked 2026-07-16); the 4 to 6 end of the range exists only through a court, where the fine bands take over by speed over the limit. A completed speed awareness course produces no code at all, which is why the same journey can leave two identical drivers with different records. Where a court disqualifies instead of endorsing points, the 4 years on the record run from conviction rather than the offence (gov.uk, checked 2026-07-17). And the code's last digit carries the role: a 2 for aiding, a 4 for causing or permitting, a 6 for inciting, so SP34 is SP30 committed through someone else's right foot.
The usual route
The standard camera outcome is 100 pounds and 3 points by conditional offer (gov.uk, checked 2026-07-16).
If it goes to court
In court the motorway carries the higher fine ceiling of the speeding offences, with the same Band A to C logic; mechanics in the fine bands guide and the speeding calculator.
