*UPDATE*
The Comelec has just published the list of 22 areas where campaign motorcased are prohibited. Motorcades on minor roads, on the other hand, while allowed, are required to submit prior notice to the MMDA so they can reroute traffic.
The Commission on Elections (Comelec) has put a ban on candidates running in the May 2013 elections from campaigning on major thoroughfares through the use of motorcades. According to Comelec Chief Sixto Brillantes Jr, the resolution will most likely take effect within the week, with 18 major roads intended to be included in the ban including EDSA, C-5, SLEX, and Taft Avenue.
Although motorcades will still be allowed on all minor streets, banning them on these busier roads will help in preventing additional traffic during the campaign season.
