To avoid losing half a day of your life doing it, use the KWUN TONG licensing Office....go outside of Holy Hour (ie 12 'till 1400) and there's no queueing...look up the location and nearest MTR on their website..failing that the guys at the front desk at the Headland can help you out....after that enjoy...you'll discover some of the worst displays of driving ability on the planet, especially at roundabouts and on the freeways..partly as a result of passing their driving tests in a car park in Sha Tin
