A driver has denied breaking the speed limit when he took an emergency supply of blood to a hospital.
Paul Stockbridge told magistrates in Stafford he should be exempt from prosecution for speeding due to his job.
The 37-year-old was taking blood from a Birmingham depot to Staffordshire General Hospital when a
camera clocked his vehicle at 41 mph in a 30 mph zone on the A449 near Stafford.
The case was adjourned until November 13 to allow prosecutors to consider the
case against the father-of-two from Great Barr, Birmingham.
Mr Stockbridge, who has worked for the service for 10 years, made the life-saving delivery in the middle of the night on March 3.
The consignment was being taken from the blood service depot near the Queen Elizabeth Hospital, Birmingham, to Stafford when Mr Stockbridge triggered a camera on the A449 at 0100 BST.
A National Blood Service spokeswoman said the organisation would not be making any comment until court proceedings were over.
