Which driving action helps reduce a liquid tanker’s rollover risk at a bend?

Revision material from the imported DVSA bank includes source-checked Lanekind learning corrections. These corrections are not newly issued official examination questions, and practice does not reproduce a live test paper.

Answer options

Rely on the number of trailer axles

Brake sharply after steering into the bend

Reduce speed smoothly before the bend

Assume a posted speed is safe for every tanker

Show the answer

Reduce speed smoothly before the bendThis was the right answer

A tanker’s high centre of gravity and moving liquid increase rollover risk. Plan a suitably low entry speed and use smooth controls. No axle or tyre arrangement removes the need for careful driving.
