This year the police will be targeting drivers going to work the morning after festive drinking this year, claiming it is one of the biggest sources of drink-driving.

An ACPO spokesperson said: ‘Fleet drivers make up a significant number of the drivers on our roads and because of that we want them to remember the dangers of drink driving.

‘They drive as part of their job and if they are caught drink driving they could lose their licence and be left without work, which could have a devastating effect on their lives.

‘Due to the work of fleet drivers, many of them are on the road in the early hours of the morning and this year we want to get the message out that they need to be aware of driving the morning after a night of drinking.’

ACPO also highlighted the fact that last year between the hours of 6am and 11am more than 400 people failed breath tests (or refused to provide a specimen), which is more than those caught for the hour before or after midnight.

Commenting on the ACPO campaign and its implications for fleet, Richard Hill, managing director of Peak Performance, said: 'We welcome the campaigns that reinforce the safe driving message and in particular the return of high-profile anti-drink-drive messages on television over Christmas.'

Ellen Booth, senior campaigns officer at road safety charity Brake, added: ‘Everyone can play a role in stamping out drink and drug driving, and the terrible tragedies that result, and that is especially true of people who drive for a living. If you know someone who takes the risk, don't let it go: speak to them. It could save their life or someone else's.’
