The Magistrate’s Court heard that Oliver Chambers’s car was leaking oil and had a balding front nearside tyre at the time of the accident, on the morning of 14 November.
Crown Advocate Carla Carvalho, prosecuting, said the collision between Chambers’s car and the motorcycle took place at around 08:30 on Claremont Road in St Saviour.
The motorcyclist sustained a broken shoulder blade in the accident.
Chambers was just over the yellow line in the road and said he had seen the motorbike “for one or two seconds”.
He applied the brakes but the car skidded into the bike.
Police went to the scene and an ambulance was called for the injured man. An X-ray showed he had a fractured scapula, or shoulder blade.
He did not require surgery but did need to keep his arm in a sling afterwards, the advocate said.
Chambers admitted the charges of driving a vehicle leaking oil and with a defective tyre, and causing injury by driving without due care and attention.
Advocate James Bell, defending, described the accident as “a misjudgement at low speed” and said: “Mr Chambers very much regrets his and is remorseful for the turn of events.”
He also pointed out that Chambers would lose his job if he lost his licence, and asked Assistant Magistrate Peter Harris to endorse his licence and impose a fine rather than a driving ban.
The Assistant Magistrate gave Chambers credit for his early guilty plea and lack of previous convictions but said: “A disqualification cannot be avoided.”
He banned Chambers from driving for three months and fined him £2,500 for causing injury, and £100 each for the two faults to the vehicle.
He also ordered Chambers to retake the driving test after the three months have elapsed.
