The numbers prepared to drinkdrive in London are higher than in the rest of the UK, but the survey by the Department of Transport, and Auto Trader magazine, paints a grim picture for road safety in the country as a whole. Of 30,000 drivers quizzed nationally, 12.6 per cent said they would risk drinking two pints of beer before driving while 1.9 per cent would risk drinking three pints. A further 78 per cent across the UK said they would drink one pint or two glasses of wine before driving.
