A van has crashed after been driven the wrong way on the M11 for nearly 50 miles.
A white Ford Transit joined the M11 at Hastingwood travelling north on the southbound carriageway and then proceeded the wrong way onto the A14.
It was stolen in Billericay at around 1.40am and travelled to the M11 along the A414 after police officers unsuccessfully tried to stop it in Ongar.
Police monitored the van using a helicopter and officers driving on the northbound carriageway.
The pursuit ended when the van collided with an HGV near Junction 24 of the A14 at Godmanchester.
Up to 100 vehicles including HGvs were forced to take evasive action as the van was driven along the motorway and A14.
A 19-year-old man from Romford is currently in custody having been arrested on suspicion of aggravated taking a vehicle without consent, dangerous driving, no insurance, no licence and failing to stop for police.
Any witnesses can call police on 101.
