Speed awareness course likely offered

At 37 mph in a 30 limit you are typically eligible for a National Speed Awareness Course — no points and no fine, but a course fee (around £80–£100) and the offer is at the force's discretion.

Last reviewed: June 2026

Every figure in this tool maps to published government and Sentencing Council guidance for England & Wales. We don't invent numbers — here is exactly where each rule comes from.

The 10% + 2 rule

Most forces won't prosecute until you exceed the limit by 10% plus 2 mph. It's NPCC guidance, not law — any speed over the limit can be enforced.

Course, fine, or court

Low-end speeds may get a speed awareness course (once every 3 years). Otherwise it's a £100 fixed penalty and 3 points, or a court summons for higher speeds.

Bands A, B & C

Courts sort speeding into three bands by how far over you were. The band sets the fine (50–150% of weekly income) and whether a ban is on the table.

Speeding penalties — your questions

The things people ask most about UK speeding fines, points and bans.

What is the 10% + 2 mph rule?
Most UK police forces follow National Police Chiefs' Council guidance and won't normally prosecute until your speed exceeds the limit by 10% plus 2 mph — so about 35 mph in a 30, or 79 mph in a 70. It is guidance, not law: a force can legally act on any speed above the limit, and cameras can be set to tighter margins.
Will I be offered a speed awareness course?
A course is usually offered for lower-end speeding — roughly between the limit + 10% + 2 and the limit + 10% + 9 — provided you haven't attended one in the last 3 years and the police consider it appropriate. It means no penalty points and no fine, but you pay a course fee (usually around £80–£100).
How much is a speeding fine?
A fixed penalty is £100. If the case goes to court, the fine is based on your weekly income: Band A is 50%, Band B is 100% and Band C is 150% of relevant weekly income, within ranges set by the Sentencing Council. Fines are capped at £1,000, or £2,500 if you were caught on a motorway.
How many penalty points will I get?
A fixed penalty adds 3 points. At court, Band A is 3 points, Band B is 4–6 points (or a 7–28 day disqualification) and Band C is 6 points (or a 7–56 day disqualification). Points stay on your licence record for 4 years from the offence.
Can I be banned from driving for speeding?
Yes. The court can impose a short discretionary ban for higher speeds (Bands B and C). Separately, reaching 12 or more penalty points within 3 years triggers a 'totting-up' disqualification of at least 6 months.
What is the New Driver Act?
If you passed your test less than 2 years ago and reach 6 or more penalty points, the DVLA revokes your licence. You then have to reapply for a provisional licence and pass both the theory and practical tests again. Just two speeding fixed penalties (3 points each) can trigger this.
Is this calculator legal advice?
No. It gives an estimate for England & Wales based on published Sentencing Council guidelines and NPCC guidance. The actual outcome depends on the police force, the court's discretion and your individual circumstances. If you've received a notice, consider speaking to a motoring solicitor.
Do you store the details I enter?
No. Every calculation happens entirely in your browser. Your speed, income and points are never sent to a server or stored anywhere. A shared link only contains the values you choose to share.
