A man has been taken to hospital following an earlier road traffic collision.
The East of England Ambulance Service (EEAST) were alerted to the A12 at Galleywood shortly after 6.37am.
Two ambulance crews, a response car, a duty officer and the trust's hazardous area response team (HART) attended the scene.
EEAST spokesman Gary Sanderson said: "On our arrival, the lorry driver was found trapped in the cab by his legs and the steering wheel.
"Paramedics and HART operatives worked extremely hard to treat, stabilise and immobilise him before he was taken to Basildon Hospital for further care, he received minor injuries."
