Police have released video of the moment officers were attacked with bricks after they stopped two men in car in Kirby, Merseyside.
The dashboard camera shows a Volvo estate being pulled over by police over before the car's driver and passenger jump out and begin throwing bricks at the patrol car, smashing the windscreen.
The officers were showered with glass but gave chase, pursuing the Volvo around Kirby before losing it on the M57.
A police investigation later identified the attackers as 33-year-old Carl Foley and 22-year-old Karl Waring, both of no fixed abode.
The men pleaded guilty and were sentenced to a total of eight years for affray, dangerous driving, driving whilst disqualified and possession of cannabis with intent to supply.
Inspector Mike McFall of Merseyside Police said: "We welcome these sentences, which should serve as a warning to anyone else considering taking such reckless action against police.
"These two dangerous offenders believed in using violence to aid their escape from police, and in doing so showed complete disregard for the safety of police and towards other road users.
"Unfortunately for Waring and Foley, they only succeeded in raising their profile as a risk to the public, which resulted in substantial terms of imprisonment."
