Consultation response: Proposed changes to penalties for motoring offences

Lowering the drink driving limit will make our roads safer for everyone, reducing collisions and saving lives.

We have submitted evidence to the Department for Transport’s consultation on proposed changes to penalties for motoring offences.

In our response, we highlighted that:

  • The drink driving limit should be reduced to 20mg (milligrammes) of alcohol/100ml (millilitres) of blood for all drivers
  • This sends a clear message that the legal level is essentially no alcohol beyond what may naturally exist in someone’s body
  • A person’s ability to drive is affected after consuming any amount of alcohol
  • Drivers with a BAC of between 20mg and 50mg alcohol/100ml blood have at least a three times greater risk of dying in a vehicle crash
  • There is strong public support for this, with 50% of people surveyed agreeing the limit should be reduced to zero or 20mg alcohol/100ml blood

Our other recommendations include:

  • If the limit is only reduced to 50mg alcohol/100ml blood, a lower drink driving limit of 20mg alcohol/100ml blood for novice and commercial drivers
  • Use of alcolocks as part of drink drive rehabilitation courses, following testing for alcohol dependency
  • Mandating drink drive rehabilitation courses for all offenders
  • Launching effective drink-driving communications campaigns
  • Improving data collection
