Which part of the right of way is specifically for vehicles to pass?

The carriageway is the part of the right of way designated specifically for vehicles to pass. This area typically consists of the lanes on a roadway intended for the movement of motor vehicles. It is where vehicles travel during normal operations, allowing the flow of traffic in both directions or, in some cases, a single direction depending on the road design.

In contrast, the sidewalk serves as a pedestrian pathway, providing a safe space for people to walk separate from vehicular traffic. The median is the strip of land that separates opposing lanes of traffic, primarily designed to enhance safety and reduce the likelihood of head-on collisions. Lastly, the shoulder is the area adjacent to the carriageway that is not used for regular traffic flow; it serves as a space for emergency stops and breakdowns or as a buffer for moving vehicles. Each of these areas plays a critical role in road safety and traffic management, but only the carriageway is specifically dedicated to allowing vehicles to pass.
