What can affect the driving stability of a towed trailer?

The correct combination of answers highlights several important factors that can affect the driving stability of a towed trailer.

1. A centre of gravity that is far back in the trailer can lead to sway or instability during towing. This configuration risks making the trailer less controllable, especially in adverse conditions.

2. Insufficient tyre pressure in the trailer tyres can cause poor handling and increase the risk of tyre blowouts, which can lead to loss of control over the trailer.

3. A leaking shock absorber reduces the trailer's ability to absorb road shocks, leading to instability and a bumpy ride, further compromising safety.

Understanding these factors is crucial, as German traffic regulations emphasize the importance of safe towing practices to ensure not only the safety of the driver and passengers but also other road users. Neglecting any of these factors can result in dangerous driving conditions and is likely to violate safety standards set by traffic regulations.
