This is due to surplus capacity in the area. Clydebank theory test centre has the capacity to deliver over 15,000 tests each year, but last year conducted just over 4,000.
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 Clydebank and Glasgow both have spare capacity it is not cost effective to keep both of them running.
Theory and practical test centres are entirely separate and delivery of the practical test remains unaffected.
