Three people were injured in a crash on the A64 which is believed to have involved a Scarborough lorry.
The accident, which involved a van and a lorry at Stockton-on-the-Forest at the junction with Barr Lane, took place just after 2.30pm on Wednesday.
One of the casualties suffered serious injuries, with two others escaping with minor injuries. All three were taken to hospital.
The road was closed in both directions while police retrieved the vehicles, causing long delays.
