Not quite, but now you know for next time!

You have to drive onto a muddy building site. Why should you switch on your diff-lock?

To make the wheels less likely to spin
Correct answer

DVSA explanation

Engaging the diff-lock means that the driven wheels are locked together. This reduces the likelihood of wheel spin. Remember to switch off the diff-lock as soon as you're on firm ground again, otherwise you could damage the transmission.
