Three lanes have reopened on the M1 after a serious crash.
Emergency services were at the scene of a collision involving at least one car which happened on the northbound carriageway just after Luton Airport.
Three fire engines were at the scene alongside paramedics, police, and highways officers.
A car crashed into the barrier on the left-hand side of the carriageway.
The vehicle was severely damaged and firefighters erected some screens on the motorway.
It's unknown at this stage what injuries, if any, were sustained in the crash.
A lorry was also at the scene although it's unclear if it was involved in the crash.
Highways England reports suggest the incident happened before 2pm this afternoon (Saturday).
The lanes reopened just after 4pm.
Traffic was solid northbound from junction 9 for Redbourn for around two hours.
Most of the queues have now cleared.
