What can help with friction-locked load securing?

Your answer is correct because all three options help with friction-locked load securing. In German traffic rules, friction-locked load securing relies on increasing the friction between the load and the vehicle surface to prevent movement. Lashing straps and lashing chains apply tension to hold the load firmly in place, while anti-slip mats increase the friction between the load and the base, reducing the risk of slipping. Using these methods together effectively secures the load during transport. This combination is important to ensure safety and compliance with load securing regulations.
