Says at pag 9:

"While driving on an aerodrome : Clear left, ahead, above and right

Scan the full length of the runway and the approaches for possible landing aircraft before entering or crossing any runway, even if you have received a clearance."

But if your truck has blind spots and vis is poor, you shouldn't be driving as fast if at all.

They have mostly glass cabs for exactly that reason. Only thing that would block your view is a passenger in the right seat.
