Ordinary drivers don't need it, but drivers on behalf of drivers need it. According to the information released by Didi official website, ordinary Didi drivers don't need to pay any fees when they join, but drivers on behalf of drivers will incur related expenses such as information, driving skills training and assessment when they join. Driving skill training and evaluation fee is set in 280 yuan, and material fee is set in 360 yuan or 340 yuan. Moreover, the platform conducts irregular comprehensive background record screening for drivers in the joining stage. If it fails to pass the screening, the platform has the right to stop providing services to drivers, and the fees incurred by joining will not be refunded.
