This is due to surplus capacity in the area. Motherwell theory test centre has the capacity to deliver over 25,000 tests each year, but last year conducted fewer than 9,000.
The Driving Standards Agency (DSA) Chief Executive, Rosemary Thew, said:
DSA relies for income on the fees we receive from our customers so we have a duty to spend that money responsibly while maintaining a good level of service.
As the theory test centres in Motherwell and Glasgow both have spare capacity it is not cost effective to keep both centres running.
Theory and practical test centres are entirely separate and delivery of the practical test remains unaffected.
