'Drink-drive' taxi driver stopped by passenger on A1(M)
A taxi driver was found to be almost five times the drink-drive limit when he was told to pull over on a motorway by a concerned passenger.
The passenger called police when he asked the driver to stop on the hard shoulder of the A1(M) near Stevenage at about 17:30 GMT on Thursday.
A breath test recorded 171mg of alcohol in 100ml of breath. The legal limit is 35mg.
The driver, from Cambridge, was arrested on suspicion of drink-driving.
Police said the 42-year-old man remains in custody in Hertfordshire.
