Road narrowingPhilippines
1. Road narrowing
A road narrowing is a section where the available width of the road or carriageway becomes smaller. The narrowing may occur on both sides, on one side only, or because one or more traffic lanes end.
Drivers should reduce speed, observe approaching and adjacent traffic, maintain sufficient lateral clearance and merge when necessary. Warning signs do not always determine priority, so drivers must follow any priority signs, lane markings and local traffic rules.
What does a road-narrowing warning mean in the Philippines?
The Philippine LTO manual distinguishes road-narrowing and narrow-bridge warnings from regulatory controls. Assess the available width and read any separate instruction governing passage.

Does a narrowing warning give you priority in the Philippines?
No. A warning describes the reduced width, rather than allocating priority or setting a numerical speed limit. Follow any separate priority signs, signals and meeting rules, and slow enough to pass safely or wait before entering.
What should you do if traffic lanes merge at a narrowing in the Philippines?
Read the lane-ending signs and markings, check surrounding traffic and signal any lane change as required. Apply the local merging rule and enter only when safe. Do not assume the driver in an ending lane always has priority, or confuse merging with meeting oncoming traffic.
