A motorist who drove the wrong way along the motorway for around eight miles was halted by Lancashire police.
The man was spotted on the M61 near junction 9 near Walton Summit, near Preston, shortly after midnight today.
He was driving northbound on the southbound carriageway.
Motorway police were alerted and the Warton-based National Police Air Service helicopter was scrambled.
The driver was then spotted – still travelling in the wrong direction – at junction 30 at Blacow.
Police were in pursuit and intercepted the car at junction 32 near Broughton.
Minutes later motorway police tweeted: “Vehicle stopped junction 32 M6 southbound, travelling northbound, now been recovered, Driver en route to hospital, having possibly had a medical episode.”
They added: “Good result, no injuries/damage, with assistance from @NPAS Warton.”

He said: “No-one was hurt and there was no collision. Fortunately the traffic would have been light at the time of night.
“The man gave a negative breath test and was taken to hospital for a check-up. Our inquiries are continuing.”
