Studies by the charity have shown that one in four drivers still get behind the wheel the morning after a heavy night’s drinking – which means they could still be over the limit – and experts believe more needs to be done to combat the problem.

Mary Williams, chief executive of Brake, said: ‘Sleeping, showering and drinking a cup of coffee do not sober you up. We want drivers to know that there is no excuse for getting behind the wheel if they still feel unfit to drive.

‘The message is simple, if you know you have to drive the next morning, do not risk drinking the night before at all.’

Brake wants the Government introduce measures to tackle drink driving. These include:

  • Random drink-drive testing in line with EC recommendations
  • ‘Booze buses’ which are mobile laboratories. Such schemes have been successful in Australia
  • More traffic police
  • A lower drink-drive limit
