What is the verge?

The shoulder is a fundamental part of the streets and highways. It is a strip of land adjacent to the road, which is generally paved and separated from the main road by a white line. Its width can vary, but it is usually wide enough to allow the parking of emergency or disabled vehicles.

Parts of the shoulder

The shoulder is made up of several parts that fulfill different functions. Next, we explain each of them:

shoulder edge

The edge of the shoulder is the part closest to the road. It is usually marked by a continuous white line that separates it from the main road. This visual limit helps drivers stay in the proper lane and prevents them from accidentally veering onto the shoulder.

Shoulder surface

The shoulder surface is the paved area that extends from the edge to the boundary with the unpaved terrain. This area is designed to support the weight of the vehicles and allow their movement in the event of an emergency or breakdown.

unpaved terrain

Unpaved terrain is the part of the shoulder that is furthest from the road. It is usually covered with dirt, grass, or gravel. This area acts as a safety barrier between the main road and the natural or artificial obstacles that may exist in the surroundings.

shoulder functions

The shoulder fulfills various functions on a street or highway. Here we mention the most important ones:

Road safety

The hard shoulder provides additional space that helps maintain road safety. It allows drivers to stop in case of an emergency or breakdown without obstructing the flow of traffic on the main road. In addition, it also provides a maneuvering area for emergency vehicles, such as ambulances or police cars.

Pedestrian and cyclist protection

The shoulder is also used by pedestrians and cyclists as a safe area to travel. It allows them to stay away from traffic and reduce the risk of accidents. However, it is important to remember that not all shoulders are enabled for pedestrian and cyclist traffic, so it is necessary to respect the current signs and regulations.

emergency parking

In the event of a breakdown or emergency, the shoulder provides adequate space to park the vehicle without obstructing movement on the main road. This allows drivers to call for help or make temporary repairs without endangering their safety or that of other road users.

Rules for driving on the shoulder

In the event of an emergency, such as a breakdown or an accident, it is allowed to drive on the shoulder to find a safe place to stop. However, it is important to do so responsibly and without endangering other road users. In addition, it is essential to properly signal the situation and request help as soon as possible.

On some occasions, it is allowed to drive on the shoulder to access private properties or service roads. However, it is necessary to do it safely and respecting traffic regulations. Visibility must always be taken into account and yield to vehicles traveling on the main road.
