One-way trafficPhilippines
6. One-way traffic
One-way traffic means that vehicles on a road or carriageway may travel only in one designated direction. The permitted direction is normally indicated by traffic signs, lane arrows or road markings.
Some road users, such as cyclists or public-transport vehicles, may be allowed to travel in the opposite direction when signs expressly permit it. A one-way road does not by itself determine the speed limit, priority or parking rules.

How should I read a one-way restriction in the Philippines?
Follow the direction designated by the street’s one-way signs and any entrance restrictions or lane arrows. A compulsory turn at one junction is different from a restriction applying along the street.
No entry.
English • Traffic sign R3-1 • No entry. No vehicles may enter from this direction.
Filipino • R3-1 • Bawal pumasok. Bawal pumasok ang lahat ng sasakyan mula sa direksiyong ito.

May cyclists travel against the general traffic direction in the Philippines?
Do not assume cyclists are exempt from a road’s direction restriction. Check whether the applicable signs, local traffic arrangement or separately designated cycle facility actually authorise movement in the opposite direction; an ordinary bicycle-route sign is not enough.
Does one-way traffic give me priority or a different speed limit in the Philippines?
A one-way restriction concerns direction. Continue to follow the applicable speed limit, signals, give-way or stop controls and junction-priority rules. Where authorised counterflow traffic exists, check for it before turning or crossing; your permitted direction is not automatic junction priority.
