How can you avoid unnecessary noise?

You answered correctly by selecting both answer 1 (replacing worn sideboard hinges or fastenings) and answer 2 (correct stowing or use of chains). Unnecessary noise can often be caused by loose parts or poorly stowed items, which rattle or make extra noise while driving. Maintaining your vehicle, such as fixing worn hinges or fastenings and securing chains or equipment, helps reduce this noise. However, increasing tyre pressure does not reduce noise and can actually make driving unsafe. For similar questions, always consider that proper maintenance and securing loads are key to minimizing vehicle noise.
