What is the definition of a cul-de-sac?

A cul-de-sac is defined as a road that leads to a dead end. This term describes a street or lane that has no direct outlet, typically ending in a circular area that provides a turnaround space for vehicles. Cul-de-sacs are commonly found in residential areas, designed to limit through traffic and create a quieter environment for residents. This layout enhances safety for pedestrians, especially children, by reducing the volume and speed of vehicular traffic.

In contrast, an intersection with multiple exits is characterized by the opportunity for vehicles to continue on different roads, which does not align with the concept of a cul-de-sac. A roundabout, while similar in terms of providing a circular turning point, allows for continuous vehicle flow from multiple directions and is not a dead-end road. Lastly, a two-way street permits traffic in both directions but does not imply the dead-end characteristic found in a cul-de-sac.
