When leaving a construction site, it is important to clean the lighting equipment to ensure that you are clearly visible to other road users and that road safety is not compromised. Removing stones trapped between the twin tires prevents them from being thrown out while driving, causing damage to other vehicles or causing accidents. In addition, loaded bulk material must be adequately covered to prevent material from falling onto the road while driving and thus posing a danger to following traffic. These measures serve to protect all road users and help prevent pollution and hazards in road traffic.
