Four-car crash shuts part of M1 in Derbyshire
A crash involving four cars led to part of the M1 in Derbyshire being shut, causing queues.
The "serious" crash happened earlier on the southbound carriageway at junction 29a of the motorway near Markham Vale.
The M1 was shut between junctions 30 and 29a southbound but has since reopened.
Derbyshire Roads Policing Unit earlier tweeted emergency services were at the scene and urged motorists to exit at junction 30 for Chesterfield.
