Nevertheless, this time it seems that restrictions are for real:
First, from July 20 to September 20, vehicles registered in Beijing with license plates ending in an odd number will only be allowed on the roads every other day. So, on days when odd numbered license plates will be allowed, vehicles with license plates ending in an even number will be banned. Taxis, ambulances, postal delivery, and other public vehicles will be exempt.
Second, Beijing's public workers have been instructed to leave their cars at home and use nothing but mass transit until the Olympic games have ended. According to the European Space Agency, the Chinese capital and neighboring provinces have the world's highest levels of NOx.
