South Central Ambulance NHS Foundation Trust was fined £500 for failing to give police information about one of its drivers who activated a speed camera.
The trust denied that it had failed to supply the information to Thames Valley Police between March 15 and April 12 but was found guilty at Banbury Magistrates’ Court on December 12.
It was required to pay a £50 victims’ surcharge and £85 costs.
Trust spokesman Michelle Archer said the trust followed procedure to let police know it had activated a speed camera by sending a written note.
She said: “Unfortunately on this occasion the response to the notification was sent but did not reach its intended destination.
“As a result of this situation we have improved our process and agreed with our colleagues in the police that we will respond electronically to these notices which will mean that there is less likelihood of such things being lost in the post.”
