Commuters in Luton, Dunstable and Leighton Buzzard can expect traffic chaos tonight after the M1 was closed both ways after a serious incident.
An air ambulance was called following what has been described as a multi vehicle incident.
Road users are advised that there are long delays on the M1 in Bedfordshire following an incident. The road is closed northbound and southbound between junctions 12 and 13.
The incident happened just after 12.30pm today (Tuesday) which has caused a full closure of the M1 in both directions.
