Is Commonwealth Avenue lethal?

First constructed in the 1960’s, the road is part of the Radial Road 7 (R-7). The speed limit is 60 km/h. Most deaths in the road are blamed on too much traffic congestion and chaos. With an estimated three to five accidents per day, the road is a nightmare of reckless traffic. Public transportation vehicles are notorious for fast and careless driving, the road has no streetlights and there is a conspicuous absence of road signs and designated motorcycle/bicycle lanes.


- High volume of vehicles passing
- Road accidents: dump trucks, cargo trucks, buses, cars, and other vehicles regularly collide while traversing the length of the highway.
- Lack of a proper drainage system often result to heavy flooding during the rainy season, effectively stranding commuters and damaging vehicles.
- Public transportation vehicles are also known to stop in inappropriate areas to pick up passengers, which result to heavy traffic, if not potentially fatal vehicle collisions.
- During collisions, the high amount of people standing or walking along makes for pedestrian fatalities as well.
