Page "Transport in Hong Kong" Paragraph 45

Most cars are right hand drive models, from Japanese or European manufacturers.

Hong Kong does not allow left hand drive vehicles to be primarily registered in Hong Kong.

However, Hong Kong registered vehicles may apply for secondary mainland Chinese registration plates, and these can be driven across the border to mainland China ; likewise, left-hand drive cars seen in Hong Kong are usually primarily registered in mainland China and carry supplementary Hong Kong registration plates.
