A foreign lorry driver who complained of feeling unwell after stopping on the motorway is reported to have blown more than three times over the drink drive limit, police said.
The man dialled for help from an SOS telephone on the M6 at Junction 7 by Perry Barr in Birmingham today, according to the Central Motorway Police Group (CMPG).
Police said the man has been taken to hospital for further assessment and is facing a blood test to establish the level of alcohol in his system.
He is not reported to have been arrested.
A spokesman for the road policing unit posted the incident on the CMPG Twitter account.
It stated: "Foreign artic (sic) driver pulls up on the M6 near Perry Barr feeling unwell.
"Blows 116mg at the roadside, which might be a contributory factor.
"Despite being over three times the drink drive limit our main priority has to be his well-being so he will go to hospital for a thorough check."
The spokesman added: "At Junction 7 of the M6 a Belgian HGV driver stops and uses the SOS Telephone for help, officers arrive to assist the male.
"Due to the smell of alcohol they breathalise him and he provides a positive sample with a reading of 116mg (in 100ml of breath). (The) legal limit 35mg #fatal5".
The CMPG said: "When a drink driver goes to hospital we gather our evidence by means of a blood sample taken by a doctor."
Police have been running a driver awareness campaign focusing on the key causes of traffic accidents: speeding, drink and drug driving, not wearing a seatbelt, fatigue, and distraction and inattention, branding them the fatal five.
A spokesman for the CMPG said "Officers remain with the 55-year-old at hospital."
