Road signage includes all tools used to regulate traffic and inform road users. It is divided into four main categories: vertical signs such as road signs, horizontal markings such as road lines, light signals such as traffic lights, and complementary devices such as barriers or delineators.
Drivers must always follow the instructions given by road signs, even when they appear to contradict general traffic rules. For example, temporary signs or detours must be followed even if the usual rules of the road would suggest otherwise.
There is a clear hierarchy between different types of signals. Instructions given by traffic officers always have the highest priority. Next come traffic lights, which override vertical and horizontal signs. Vertical signs take precedence over horizontal markings. This hierarchy is essential for understanding which instruction to follow in case of conflict.
Temporary signs may be installed in special situations such as roadworks or emergencies. These must also be obeyed, even if they differ from normal signage.
Road signs must be uniform throughout the country so that users can easily recognize them wherever they are. They must also be properly maintained. If they are damaged, not visible, or no longer useful, they must be replaced or removed.
It is forbidden to place unauthorized elements on road signs, such as advertisements or stickers, as they may cause confusion and reduce safety. Signs must also be installed in a way that does not obstruct movement, especially for people with disabilities.
Road signage is mandatory on all public roads, including private roads open to public use. Even in private areas not open to the public, any signage used must comply with official standards.
Drivers of rail vehicles operating on public roads must also follow road signage, unless specific rules state otherwise.
For the theory exam, it is essential to remember both the types of signage and the hierarchy of priority among them.
