Tougher fines for the worst speeders come into force
The changes, which are being imposed by the Sentencing Council, mean fines for the worst speeders will start at 150% of their weekly income, up from 100%.
This would apply to drivers who, for example, go at 41mph or more in a 20mph speed limit zone, 51mph or more where there is a 30mph limit or over 101mph on a motorway.
Sentence levels for less serious offences are not changing.
The maximum fine for speeding is £1,000, unless it takes place on a motorway, in which case it is £2,500.
The higher penalties are being rolled out across England and Wales following calls from respondents to a consultation who said previously guidelines did not properly take into account the increase in potential harm that can result as speed above the speed limit increases.
Here is a summary of the fines you could face:
