Michael Dodds, 38, was also ordered to carry out 150 hours’ unpaid work for that offence, committed during the early hours of September 10 at Lowood Bridge and on the A6091 bypass at Tweedbank.
The court was told that several witnesses had contacted police expressing concerns about the behaviour of Dodds, and when officers arrived, they found him slumped over his car’s steering wheel.
He passed a roadside breath test but appeared to be impaired due to drugs and was arrested.
He refused to be examined by a doctor or to give a sample of blood, however.
Defence lawyer Ed Hulme said it was accepted that his client was unfit to drive after suffering a reaction to prescribed drugs, though.
Dodds, of Newtown, was also placed under supervision for 12 months.
