A man stopped as he drove a BMW on the motorway was found to have cocaine residue in his body.
Jordan Leak, a 22-year-old salesman, of Waring Drive, Thornton, pleaded guilty to drug driving.
He was disqualified from driving for 16 months and fined £120 with £85 costs plus £30 victims’ surcharge.
Prosecutor, Martine Connah, said police received a tip-off and stopped Leak on the M55 at Kirkham, on May 6 at 2.40am.
A blood test showed 100 micrograms of a cocaine residue in his body – 50 is the legal limit.
David Charnley, defending, said Leak would lose his job.
