Beijing TV (BTV) has reported that starting today (September 9, 2014) motorcycle enforcement will be strict.

Apparently, the last couple of weeks have been a "grace period" during which a public education campaign has been in effect. For example, over the holiday weekend that just ended, all of the electronic information boards on the Ring Roads have been constantly displaying "Motorcycles are forbidden on Ring Roads." Usually, these boards only display information about traffic jams, etc. It seems a little more serious than prior "crackdowns."

BTV also reports that traffic camera enforcement will be used on the Ring Roads, as well as for 京B plates within the 4th ring road.
