Una calzada, también llamada carriageway en inglés, es la parte de una carretera destinada principalmente al movimiento de vehículos. Puede llevar tráfico en uno o ambos sentidos y dividirse en uno o varios carriles.
La calzada es solo una parte del entorno vial. Vías ciclistas, aceras, arcenes, zonas de estacionamiento y otras instalaciones junto a la carretera pueden constituir partes separadas y estar sujetas a normas distintas.
What is a roadway?
A roadway, or carriageway, is the part of a road primarily intended for the movement of vehicles.
Is the roadway the same as the entire road?

Is a traffic lane the same as a roadway?
No. A traffic lane is a portion of the roadway intended for a line of moving vehicles. A roadway may contain one or several lanes.
Can a roadway carry traffic in both directions?
Yes. A roadway may carry two-way traffic or may be restricted to traffic travelling in only one direction.

Where should drivers normally travel?
Drivers normally use the roadway and the traffic lanes intended for their direction of travel, except where another part of the road is specifically provided or permitted for their vehicle category.
Can cyclists use the roadway?
Yes. Cyclists may or must use the roadway when permitted by local rules, particularly where no applicable cycle facility is available or compulsory.
Can pedestrians use the roadway?
Pedestrians may sometimes use the roadway when no suitable pedestrian facility is available, subject to the local rules governing their position and direction of travel.
Can road markings divide a roadway into lanes?
Yes. Continuous or broken longitudinal road markings commonly divide a roadway into individual traffic lanes and regulate how drivers may move between them.
Can different parts of the same road have different rules?
Yes. The roadway, cycle paths, pavements, parking areas and other sections may each have different permitted users and traffic rules.
