A woman who drives a G-registration Austin Maestro has told of her shock after receiving a speeding ticket claiming she was travelling at 480mph.

　　Joanna James, 28, was allegedly clocked as she drove along a road in Bridgend earlier last month. The mother-of-three, who bought the silver-coloured car for￡100 in June, said it started to shake when it reached the motorway speed limit of 70mph.

　　A spokeswoman for the South Wales Safety Camera Partnership said the speed given on the ticket was down to a clerical error and a rectified notice, stating 48mph, had been issued.

　　Mrs James, who had her three-year-old daughter Chloe in the car with her on the night of the alleged offence, said she had been shocked when the letter arrived because she had not believed she had been speeding at all. "Then my husband said, 'Hang on, you were doing 480mph," said Mrs James, of Sandfields, Port Talbot.

　　Her husband, Kenneth, who carries out mechanical work on the car, said: "I am waiting for Nasa to ring up for the diagram of the engine."
