Vehicles used for roadworks and maintenance, how will they signal their presence when they are carrying out repair works on the carriageway?
Special vehicles
Explanation
Vehicles designated for construction and services must use a **flashing light with self-yellow lights** to signal their presence when performing repair work on the roadway. This yellow light is essential for other drivers to easily identify that there is a vehicle working on the road, which helps prevent accidents and maintain road safety.
- **Yellow light**: Vehicles performing construction or special services on the road must have a yellow light on. This light is used to alert other drivers of their presence and ensure a safe distance is maintained.
- **Construction signs**: In addition to the yellow light, roads under construction are usually marked with vertical danger signs and yellow markings on the pavement, reinforcing the warning that work is being done on the road.
- **Visibility and safety**: The yellow light is placed at the highest point of the vehicle so that it is visible from afar, ensuring that drivers can see the vehicle in advance and take necessary precautions.
In summary, the use of yellow lights on construction vehicles is a crucial safety measure to warn drivers and prevent accidents in work zones.
