Bank holiday travellers faced huge tailbacks on one of the country's busiest motorways on Friday evening as police closed a stretch of the M6 while they investigate a "suspicious vehicle" at a service station.
Warwickshire Police have closed the M6 in both directions between junction 2 near Coventry and junction 4 near Coleshill.
Motorists were being advised to avoid the area and plan alternative routes.
The Highways Agency said they were made aware of the incident by the police at 3.30pm.
A spokesman said he understood the vehicle was parked in the car park of the northbound side of Corley services.
In a statement Warwickshire Police said: "Police are dealing with an incident on the M6 motorway near Corley services.
"The motorway has been closed in both directions and motorists are advised to find alternative routes."
Warwickshire Police later posted on Twitter that the incident was "coming to an end".
The force tweeted: "Motorway incident coming to an end. Hoping to open the motorway soon. More details will be posted later."
