A drunk taxi driver who was five times over the drink-drive limit was told to pull over on a busy motorway by his concerned passenger.
According to the Sun, the petrified traveller called police after asking the driver to pull over on the hard shoulder of the A1 motorway near Stevenage last month.
A breath test found the driver had 171mg of alcohol in 100ml of breath.
The legal limit is 35mg – meaning he was almost five times over.
Police arrested the driver, from Cambridge, on suspicion of drink-driving.
A 42-year-old man was held in custody in Hertfordshire.
BCH Road Policing shared a picture of the man’s breathalyser result on Twitter.
They wrote: “Taxi passenger on A1M Herts thought his driver may be drunk and called police… he was right! Limit is 35, blew 171.”
