Changes in sentencing guidelines mean that there are tougher penalties for drivers going at excessive speeds.
The minimum fine is still £100 and three points on your licence. But for more serious offences, you could be fined up to 175% of your weekly income.
Our speeding fine calculator should help you get a better idea about what these fines are likely to be. Enter your annual salary, select a speed limit and a driving speed and you'll see what the likely penalty would be.
These figures represent the typical fines for each band (A, B and C). Serious offences and mitigating circumstances could raise or lower the fine within that band.
Also, the maximum possible fine for speeding is £1,000 on normal roads, and £2,500 on motorways.
