If you are an experienced driver from China and have never driven on UK roads, it may prove beneficial to take a short refresher driving course. This will typically consist of a small amount of driving lessons to help build confidence and safety from driving on UK roads – particularly beneficial due to the UK driving on the opposite side of the road to China.
The UK practical driving has many different requirements to the Chinese test, so if you plan on taking a UK test but hold a full Chinese driving licence, refresher lessons will enable you to learn all is needed to pass.
