Caught doing 100 mph in a 70 mph limit?

That's 30 mph over the limit. Here's the likely outcome under the Sentencing Council guidelines for England & Wales — and what it means for your licence.

Court summons likely — Band BBand B

At 100 mph in a 70 limit this falls in sentencing Band B. The court can impose 4–6 penalty points or a 7–28 day disqualification, plus a fine of 75–125% of weekly income.

What 100 in a 70 actually means

Most forces apply an advisory enforcement tolerance of 10% + 2 mph — about 79 mph in a 70 zone — before they prosecute. This is NPCC guidance, not law: a force can act on any speed over the limit.

A National Speed Awareness Course in a 70 limit is usually offered between 79 and 86 mph, and only if you haven't taken one in the last three years. Above that window the standard route is a £100 fixed penalty with 3 points, and higher speeds are referred to court under sentencing Bands A, B and C.

At 100 mph this case falls into sentencing Band B, which means a court summons.

What to do if you've been caught

  1. Wait for the paperwork. If a camera or officer recorded you, expect a Notice of Intended Prosecution (NIP) within 14 days, then a Section 172 request to confirm the driver.
  2. Respond to the Section 172 in time. Failing to name the driver is itself an offence carrying 6 points and a fine — often worse than the speeding.
  3. Check the options offered. You may be offered a course, a fixed penalty, or a court summons. Take a course if eligible — it keeps points off your licence.
  4. Get advice for court cases. If the speed is high enough for court (Band B or C), a motoring solicitor can advise on mitigation and disqualification risk.
