This was contrary to Road Vehicles Regulations 1986, the Road Traffic Act 1988 and the Road Traffic Offenders Act 1988.
Tindall, of Sicey Avenue, Sheffield, was fined £220, given six points on his licence and ordered to pay £88 surcharge and £90 costs.

The case was heard at Bath Magistrates’ Court on February 14.
