A van driver ignored a police roadblock and attempted to drive through it because he feared his children might be involved, a court heard.
Francis Casey, 33, was driving his van along Green Lane when he arrived at the scene of a serious collision between a motorcyclist and a car.
But instead of stopping he attempted to plough through the police cars by driving into a ditch at a 45 degree angle, Chelmsford Crown Court heard.
At a sentencing hearing on Wednesday (September 18) Casey was banned from driving for 12 months, handed a 15-month supervision order, ordered to take part in a thinking skills programme, and made to take a retest
The court heard a police officer at the scene tried to run up to the van and bang on the window shouting "stop, stop", but Casey continued to drive.
Polio sufferer Casey, who walks with a crutch because of his illness, was not involved the earlier crash between the silver Ford Ka and the white Honda motorbike on April 14.
The 44-year-old biker, from Mayland, was airlifted to Addenbrooke's Hospital in Cambridge, suffering serious non life-threatening arm and chest injuries.
The occupants of the silver Ka, a man and a woman in their 80s from Burnham on Crouch, were treated for shock but otherwise uninjured.
Casey had been staying with his family at a campsite near the accident site and had gone out to get gas.
He claimed he was concerned about the welfare of his children when he saw the accident but police arrested him and he was charged with failing to stop for police and dangerous driving - charges he admitted at an earlier court hearing.
Judge David Turner said Casey drove "arrogantly, thoughtlessly and anti-socially".
"I find it very hard to believe, as you claim, that your concern for your children meant that they may be somehow involved in the accident.
"That concern could have been met in many different ways, but instead you drove dangerously along the side of a police car and into a ditch and then when you were asked about it you lied."
The court heard Casey five previous convictions for seven offences over 12 years.
