When I did the test the 'medical' test was just an office 'round the back of the cop shop. The medical technically consisted of a raft of exhaustive tests, to make sure that you were 'good enough' to join the hapless sea of imbeciles which is China traffic.

In reality it was two doctors testing eyesight and colorblindness with chart praying that you'd fail so they could extort a few yuan to say you'd actually passed. Why the F**k colorblindness when you can fly a 747 and be colorblind, I'll never quite understand.....
