A man had to be cut free from his vehicle after it crashed into the central reservation on the Calderdale Way by the slip road to Park Wood.
Elland and Brighouse firefighters cut through the roof of the blue Nissan Micra so paramedics could reach the driver.
He was taken to Huddersfield Royal Infirmary with back and neck injuries.
The air ambulance was called out but was not needed.
The accident happened at 2.10 pm (Thurs) and the road was partially closed for around 40 minutes.
