Heavy objects including a drill were hurled at a police car as the officer chased a driver who fled through Cardiff at speeds reaching 120mph.
Cardiff Crown Court heard Jamie Brown, 21, spun the wheels of the Ford Focus he was driving as he quickly accelerated away from the police vehicle’s siren and blue flashing lights.
Judge Richard Twomlow said: “It is extremely fortunate that nobody was seriously injured or killed.”
The incident happened around 10.20pm on Saturday, November 16 in Ely when it was dark and rain had made the road surface slippery.
Kathryn Lane, prosecuting, said the officer noticed the defendant’s car because the number plates did not have a manufacturer’s mark on them, suggesting they were fake.
The officer followed the Focus on to Snowden Road and intended to speak to the driver, but he accelerated away.
Ms Lane said: “The defendant accelerated quickly and his wheels spun.”
The court heard the officer turned on the siren and blue lights and chased Brown along Archer Road, Pethybridge Road and Llewellyn Avenue.
Prosecutors said the defendant was driving “well in excess” of the 30mph speed limit – going at more than double the limit at times.
He also drove straight through several red lights and went the wrong way around a roundabout, putting other road users in danger.
The court heard he reached 120mph on the A4232 and M4 , forcing other drivers out of the way by tailgating them.
Ms Lane said: “The officer became aware of a number of items being thrown out of the window and striking the front of the police vehicle.”
She added the defendant almost caused a collision as objects, including a “large and heavy” drill, were launched out of the Focus.
Brown took the A4119 towards Llantrisant and failed to stop after hitting the back of a Ford Galaxy on Ty Nant Road in Creigiau .
The court heard he then hit a Volkswagen Passat with four people inside, seriously damaging both cars.
Prosecutors said the police officer saw three men jump out of the Focus and run away. He gave chase and there was a “violent struggle”, prompting him to use his pepper spray.
Brown was arrested and taken into custody. He accepted he did not have insurance and said when he was charged: “I wish I had stopped straight away.”
Checks revealed the Focus had false number plates and Brown was uninsured with no driving licence.
The court heard all four people in the Passat were “in shock” and driver Allan Cooze suffered whiplash and a fractured elbow.
In a statement read out in court, he said he had been in “constant pain” since the crash and could not go back to work because he could not lift anything.
He said he was fit and active before the incident, but now cannot tie his shoes or dress himself properly without help. He cannot sleep and feels helpless.
Mr Cooze said he used to be a confident driver, but now feels “hyper vigilant” and is looking to get some counselling.
The court heard Brown was sent to a young offender institution for six months in 2017 for burglary.
These offenders were sent to prison last month:
Brown, from Tan Y Bryn in Beddau , admitted driving dangerously without a licence or insurance and three counts of failing to stop.
Lloyd Jenkins, defending, said: “He has brought shame on himself and his family.”
The court heard he was made redundant, but managed to find a new job washing dishes at the Harvester in Talbot Green.
Mr Jenkins said: “This was an isolated incident. It was completely out of character. He has learned his lesson.”
Judge Twomlow told the defendant: “This was an appalling piece of dangerous driving.”
Brown was sent to prison for 14 months and disqualified from driving for four years from the time of his release. He will have to pass an extended re-test before being allowed behind the wheel again.
