A warning sign is a traffic sign that alerts drivers to a potential danger or change in road conditions ahead, giving them enough time to slow down and react safely. These signs warn about hazards such as sharp bends, pedestrian crossings, slippery surfaces, merging traffic, animals on the road, or upcoming intersections. Their purpose is not to forbid or command anything, but simply to prepare drivers for situations that require extra attention.

This traffic sign indicates a warning for low-flying aircrafts. It alerts road users that aircraft may fly low over the road, potentially causing noise distraction or sudden overflight surprises. Drivers should remain focused despite potential noise or shadow distractions. Typical Locations: airports, military airbases, landing strips, airshows or heliports.

This traffic sign indicates a warning for cattle. It alerts drivers to the possible presence of cows, bulls, or other domestic livestock on or near the road. It helps prevent accidents, especially in rural or agricultural areas. Cattle may cross or walk along the road, either freely or under the supervision of a herder. Drivers should: slow down, be ready to stop suddenly, avoid honking or sudden movements. Typical Locations: farmlands, pastures near roads, unfenced grazing areas, mountain roads.

This traffic sign indicates a warning for a speed bump. It alerts drivers of an upcoming raised bump in the road designed to slow down traffic. Drivers should reduce speed to avoid discomfort, damage to the vehicle, or loss of control when driving over the bump. Typical Locations: residential areas, school zones, hospitals, pedestrian zones, roads with traffic calming measures.

This traffic sign indicates a warning for an uncontrolled crossroad. It alerts drivers that a crossroad without traffic signals or priority signs is ahead. Drivers should slow down and be alert for traffic from side roads that may not stop. Yield according to local right-of-way rules (e.g., in many European countries, give way to the right). Typical Locations: Rural areas and roads where no clear priority is assigned.

This traffic sign indicates you have to give way. It alerts drivers to yield the right of way to other road users. Drivers must slow down and yield to traffic on the intersecting road. Stop if necessary and proceed only when the way is clear. Common at: minor roads joining major roads, roundabouts and merging lanes.

This traffic sign indicates a warning for an uncontrolled T-crossroad. It alerts that you are approaching a T-junction where no traffic signs or signals regulate priority — making it an uncontrolled intersection.

This traffic sign indicates a warning for an uncontrolled Y-crossroad. It alerts drivers to an upcoming Y-shaped intersection, where two roads branch off at an angle, and no priority rules are explicitly posted — it's an uncontrolled junction. Drivers must slow down, choose a direction, and yield as necessary based on default traffic priority rules.
