What must you remember when loading a trailer?

You’ve selected the correct combination of answers regarding loading a trailer.

1. Ensuring that the trailer is securely packed is vital for safety. Loose items can shift during transit, leading to instability or loss of control, which could cause accidents.

2. The regulation about not projecting more than 1 meter beyond the rear reflectors, unless specially marked, helps maintain visibility and safety on the road. If cargo extends too far, it could pose a hazard to other drivers, especially in the case of sudden stops.

It's important to recognize that all options in such questions reflect key safety regulations that help ensure the stability of your vehicle and the safety of all road users. Failure to adhere to these can result in legal consequences and accidents.
