For the purpose of improving the Department's customer services, the validity of Hong Kong full driving licences has been changed from 1 year or 3 years to 10 years since 2 June 1997. For those aged over 60, a driving licence with validity of 9 years or below will be issued. For the convenience of customers, the implementation of the 10-years licence reduces the licensee's frequency of submitting the application for renewal of driving licence.
