One-way trafficItaly
10. 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 Italy?
Follow the street’s one-way direction and any specifically marked lanes. Italian rules distinguish ordinary carriageway direction from doppio senso ciclabile, a separately regulated cycling arrangement.

May cyclists travel against the general traffic direction in Italy?
The current Road Code recognises lanes for two-way cycling and requires cyclists to use the applicable reserved facilities where provided. A cyclist cannot infer general counterflow permission merely because the street has a low speed limit; check the actual designation.

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