The Land Transport Department has issued new criteria for big bike riders, saying they must bring medical certificates when applying for a driving license.
The new rule requires big bike riders to have more training and tests.
Medical certificates for driving license application and renewal must prove that the driver does not have diseases that medical professionals deem unsafe for riding.
New diseases which are being considered are epilepsy, diabetes, high blood pressure, bipolar disorder, autism and a height of less than 90 centimetres.
The medical certificates will be needed for all types of driving licenses -- for personal cars, motorcycles and public vehicles.
The new rules will start on Feb 19.
Training and tests for big bike riders were being formulated.
The government stepped up rules as the vehicles presented a high risk of road accidents.
