A priority road is a road on which drivers normally have priority over traffic entering from intersecting side roads.

It is normally indicated by a priority-road sign at or near its beginning. A corresponding end sign indicates where its continuing priority status stops.

Normally, yes, while the priority-road designation remains in force. Drivers must still observe traffic lights, authorised officers and any signs applying at a particular intersection.

Not necessarily. A priority road commonly continues across successive intersections until an end sign or another legally defined change in priority.

Side roads are commonly controlled by give-way or stop signs, but sign placement and legal requirements differ between countries.

Where the priority-road signs apply, drivers entering from intersecting side roads must normally give way regardless of whether they approach from the left or right.

No. A priority-road sign normally creates continuing priority across several intersections. Another sign may grant priority only at the next intersection.

No. The priority route may turn at an intersection. A supplementary diagram may show which branch retains priority.

Priority does not remove the duty to signal. Use the direction indicators whenever following or leaving the priority route involves a change of direction or lateral movement.

No. Approach every intersection at a safe speed and remain prepared for another road user to fail to give way.

No. The applicable general, zonal or posted speed limit remains in force.

Functioning traffic lights normally control the intersection instead of the priority signs. Local rules determine what applies when the lights are switched off or flashing.

Yes. Instructions from an authorised traffic officer normally take precedence over traffic signs and ordinary priority rules.

Yes, where the applicable crossing rules give them priority. Priority over side-road traffic does not remove duties towards pedestrians.

You must still give way to oncoming traffic, pedestrians, cyclists and other road users where the normal turning rules require it.

Cyclists using the road or a continuing bike path may have priority over entering or turning traffic, depending on signs, markings and local law.

Not automatically. Roundabout priority is determined by its own signs, signals and local rules.

Priority-road status does not itself permit or prohibit overtaking. Drivers must follow the ordinary overtaking rules, markings and visibility requirements.

This depends on local law and signs. Some countries prohibit parking on priority roads outside built-up areas, while other parking rules may apply inside towns and cities.

No. A driver entering the road from a property, parking place or other off-road location normally performs a manoeuvre and must give way to road users already present.

No. Do not enter when congestion would force you to stop inside the intersection and obstruct crossing traffic.

Its continuing priority normally ends at an end-of-priority-road sign. Drivers must then follow the signs or ordinary priority rule applying at the next intersection.
