Pulled to the left when being passed by Big Rigs

High pressure around the front of the truck (bow wave), and low pressure on the sides of the truck. Bow wave will push you away and the low pressure area will pull you toward the truck. Just the way it is.

The larger your tv is, the less it will affect it.

Just keep your eye on what’s coming behind you so you can deal it. Real fun when you are in a situation where you have a semi on both sides of you at the same time with one passing beside you and the other just starting to pass.
