Developed in response to incidents in which road workers were killed or injured while working on expressways, this vehicle not only has the important mission of protecting human lives, but also holds out the possibility of transforming approaches to roadworks. Technical skills and the bold vision of ensuring a safe working area in the hazardous expressway environment have been used to add transformational capabilities to a trailer truck that meets standard size specifications under the Road Transport Vehicle Act, resulting in a vehicle without parallel anywhere in the world. Extendable beams function as buffers, ensuring the safety of roadworkers even in the event that a car traveling at 80 km/h collides with the truck. Protecting roadworkers and roads ultimately ensures driver safety and a better transport culture. With infrastructure maintenance technology growing in importance, this vehicle itself is a groundbreaking design based on the new value of protecting both people and cars.
