Special vehicles
Explanation
Special **vehicles** that perform work on roads have certain obligations to ensure safety. One of the mandatory elements they must carry are **hazard pre-signaling devices**. These devices are essential to warn other drivers about the presence of a vehicle that is performing improvement or maintenance tasks on the road.
- These vehicles must have a **yellow light on** while working, which helps them be visible to other drivers and thus avoid accidents.
- The yellow light must be on from the moment the vehicle enters highways or expressways until it reaches its destination.
- Although these vehicles do not have priority to pass or overtake, proper signaling is crucial for road safety.
Therefore, hazard pre-signaling devices are a mandatory element for special vehicles, ensuring that their presence on the road is clearly visible to everyone.
