An owner chooses the plate number for his new energy car in Shenzhen, south China's Guangdong Province, Dec. 1, 2016. China's traffic management authority has designed special plates for new energy vehicles to help traffic police differentiate them from standard cars. It is important that police can recognize new energy vehicles in order to enforce the preferential policies that some local authorities apply to greener cars to help cut emissions and ease traffic.
