What can be used to secure loads carried in a car?

The combination of options 1 (luggage net), 2 (tensioning belt), and 3 (anti-slip mat) is correct because each of these items serves a specific purpose in securing loads in vehicles.

According to German traffic regulations, securing a load is crucial for safe driving and compliance with the law. The luggage net helps to keep smaller items contained and prevents them from shifting during transit. The tensioning belt provides firm attachment for larger or heavier loads, ensuring they do not move or fall while the vehicle is in motion. The anti-slip mat creates friction between the load and the vehicle surface, further preventing any sliding.

Using all three methods together maximizes safety by minimizing the risk of shifting cargo, which can lead to accidents or obstructing the driver's view. It is essential to adhere to these practices to comply with German traffic laws, which mandate that loads must be secure to avoid endangering road safety.
