Three lanes of the M1 were closed off following a lorry crash near Bricket Wood.
The southbound lanes were cordoned off after the accident involving a silver Hyundai i30 and a yellow P&O Ferries between Junction 7 and Junction 6A at 1.30pm.
The lorry has been left smashed through a crash barrier and partly on a field.
The road has since been reopned.
