The ACPO Guidelines are: The guidance to police officers is that it is anticipated that, other than in the most exceptional circumstances, the issue of fixed penalty notices and summonses is likely to be the minimum appropriate enforcement action as soon as the following speeds have been reached:

Limit     Fixed Penalty  Summons

20 mph      25 mph       35 mph

30 mph      35 mph       50 mph

40 mph      46 mph       66 mph

50 mph      57 mph       76 mph

60 mph      68 mph       86 mph

70 mph      79 mph       96 mph 

Fixed penalty of 1. £60 (pending) 2. Licence endorsed with 3 penalty points Magisterial discretion (level 2) maximum of: 1. £1000 fine 2. Licence endorsed - range of penalty points available 3. Disqualification 4. Compulsory re-testing

This guidance does not and cannot replace the police officer's discretion and they may decide to issue a summons or a fixed penalty notice in respect of offences committed at speeds lower than those set out in the table. Moreover, in particular circumstances, driving at speeds lower than the legal limit may result in prosecution for other offences, for example dangerous driving or driving without due care and attention when the speed is inappropriate and inherently unsafe.
