1. 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 Uruguay?

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.

May cyclists travel against the general traffic direction in Uruguay?

Cyclists have no general exemption from the established one-way direction: the national regulation applies ordinary driver duties to them. Follow the direction set for the carriageway or any separately designated cycle facility. A general bicycle-route sign alone does not authorise riding against the traffic direction.

Does one-way traffic give me priority or a different speed limit in Uruguay?

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.
