Traffic signs

A traffic sign is a standardized visual symbol placed along roads to guide, warn, or regulate drivers, cyclists, and pedestrians. These signs provide essential information about road conditions, rules, directions, and potential hazards, helping to ensure safety and smooth traffic flow. They come in various shapes and colors—such as triangular warning signs, circular prohibitory or mandatory signs, and rectangular information signs—each designed for quick recognition and clear understanding.

1. Warning for a danger with no specific traffic sign

This traffic sign indicates a warning for a danger with no specific traffic sign. It's a general warning sign used when there is a hazard ahead that does not have its own dedicated warning sign. For examples: road accidents, flooded roads and roads blocked by fallen trees. It usually has a supplementary sign attached that tells drivers of what hazard to expect.

2. Warning for accidents

This traffic sign indicates a warning for accidents. It's a warning sign that alerts drivers to a location where accidents are likely to occur, or where a recent accident may have happened. Drivers should slow down, stay alert, and increase following distance. Common Locations: blind curves, intersections, tunnels, steep slopes or high-crash zones.

3. Warning for low-flying aircrafts

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.

4. Warning for cattle on the road

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.

5. Warning for crossing deer

This traffic sign indicates a warning for crossing deer. It alerts drivers to the potential presence of deer or other wild animals crossing the road. It is essential in areas where wildlife-vehicle collisions are common. Wild deer may suddenly cross the road, especially at dawn or dusk. Drivers should: reduce speed, stay alert, watch both sides of the road. Typical Locations: forests, national parks, wildlife corridors or countryside highways.

6. Warning for a movable bridge

This traffic sign indicates a warning for a movable bridge. It alerts that a movable (opening) bridge is ahead — such as a drawbridge or swing bridge — which may open for boat traffic. Drivers should be prepared to stop when the bridge is open and to expect possible traffic delays. It often accompanies barriers, lights, or warning bells at the actual site. Common near: rivers, canals, or ports.

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.

10. Warning for an uncontrolled crossroad

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.
