Vehicle testing centers face tests

Beijing's vehicle testing centers have been warned that they could lose their licenses if they fail a new annual inspection, part of an improved supervisory system to be rolled out on Thursday.

Three city departments, including the Environmental Protection Bureau, issued regulations earlier this month to increase oversight of the centers and remove more polluting cars from roads to help improve air quality.

Inspections will now be carried out annually at 35 centers in Beijing, with each center receiving a score based on the number of rule violations it discovers. The best score is zero, while the worst allowable is 12.
