After coupling to a semitrailer, how should you leave the landing gear (front trailer supports) before pulling away?

Correct answer: Cranked all the way up, handle stowed in its bracket.

Answer options

  1. ACranked down three turns from the top, handle stowed in its bracket
  2. BCranked only halfway up, handle removed from its bracket
  3. CCranked all the way up, handle stowed in its bracket Correct

Why

Landing gear left partly down can catch on railroad tracks or other objects in the road, so crank it fully up and secure the handle before you drive.
