A car transporter ploughed into a police vehicle which was slowing traffic following an earlier incident on the A92 in Fife.
A police officer was seriously injured in the collision, which saw the car knocked into the air, off the road and into a ditch.
The crash occurred on the westbound dual carriageway between Cowdenbeath and Crossgates on February 27 2020.
The injured police officer was airlifted to hospital after the collision.
The police 4X4 had been stationary and helping a vehicle which had stopped when it was hit at around 1.40pm.
Another officer had been standing in the road diverting traffic into outer lanes.
The transporter driver, Alan Robinson, 40, of Myreside Crescent, Glasgow, went on trial at Dunfermline Sheriff Court.
Robinson denied a charge of dangerous driving and the jury found him guilty of careless driving instead.
Collided with police car
He was convicted of causing serious injury to a police constable by driving a lorry carelessly on the A92 and failing to observe and react to a stationary police car parked on the roadway with its emergency lights activated.
He also failed to react to another officer standing on the roadway directing him to move into another lane.
He collided with the police car, which was propelled into the air and down a verge.
He struck a police officer causing serious injury and also two females, standing on the grass verge, who were injured.
Robinson said he could not give any explanation for failing to see the police vehicle earlier.
“The position of the sun may have played a part in it.
“I only saw the police officer at the last minute,” he added.
Robinson said he tried to take action to avoid a collision but it was too late.
Sheriff Susan Duff called for reports and Robinson will be sentenced on July 28.
