When behind a truck look directly in the truck's mirrors, you may even see the driver see you (if she/he's an aware driver). If you can't see a mirror or the driver in it, you are in a danger zone. Only pass a truck if it is stationary on the inside, if it is moving DO NOT UNDERTAKE it.
Only pass a truck if it is stationary on the inside, **and there is no possibility of it moving while you're passing it.
