To be implemented by next year:

Currently, the speed limit set along the main stretch of EDSA is a maximum of 60km/h. In the following weeks, that may soon be reduced to only 50 km/h as the Metro Manila Development Authority (MMDA) has announced on Wednesday.

And for those from Quezon City, much lower speed limits:

As a safety measure, the speed limit for all types of vehicles using city roads, except for selected thoroughfares, is set at 30 kilometers per hour. For barangay roads, the limit is 20 kph.

With the exception of Commonwealth Avenue where vehicles can run at 60 kph, cars and motorcycles are limited to 50 kph on Santolan Road, Aurora Boulevard, Kamuning Road, Batasan Road, Regalado and Quirino Highways, E. Rodriguez Sr. Avenue, Quezon Avenue, West Avenue and Mindanao Avenue.

Trucks, buses and tricycles can run only up to 30 kph on all city roads, except for Commonwealth Avenue where the speed limit for such vehicles is set at 50 kph.
