Signs

Understanding the Hierarchy and Types of Signs

The most critical rule for interpreting traffic signs is the hierarchy of authority. Signals from traffic officers are supreme and override all other rules, signs, and lights. Below officers are circumstantial signs used for roadworks and emergencies, which take precedence over permanent installations. These are followed by traffic lights, then vertical signs (like speed limits and warnings), and finally, road markings on the pavement. When two signs of the same type conflict, you must always obey the more restrictive one. In the absence of any signals at an intersection, the default rule is to give way to vehicles approaching from your right.

Warning, Regulatory, and Priority Signs

Vertical signs are categorized by their shape and purpose. Triangular signs with a red border are warning signs, alerting you to upcoming hazards such as dangerous bends, slippery roads, or intersections. Circular signs are regulatory: those with a red border prohibit actions, such as exceeding a speed limit (e.g., a circle with '50' inside) or overtaking. Blue circular signs impose a mandatory action, such as following a specific direction or maintaining a minimum speed. Priority signs, like the octagonal STOP sign (requiring a complete halt) and the inverted triangle Yield sign (requiring you to give way), govern right-of-way at junctions.

Traffic Lights and Road Markings

Traffic lights control the flow of traffic, with red meaning stop before the line, green meaning proceed if the way is clear, and steady amber meaning stop if it is safe to do so. Special lights exist for cyclists and buses, and lane-specific lights (like a red 'X') must be obeyed. Road markings provide continuous guidance. A solid continuous white line must never be crossed. A broken line may be crossed for manoeuvres like overtaking if it is safe. Markings like lane arrows dictate mandatory directions, and a yellow grid at an intersection must not be entered unless your exit is clear.

Special Circumstances and Roadworks

Always be aware of special conditions. Roadworks zones are indicated by signs with a yellow background and by yellow road markings, which temporarily override standard white markings. Supplementary panels below a main sign can limit its application, for example, to a specific distance, a certain length of road, or only during specific weather conditions like rain or fog. Even when you have priority, you must always be prepared to facilitate the manoeuvres of other vehicles to ensure overall road safety. Signs apply to the full width of the carriageway unless lane markings or specific placement indicate otherwise.
