While there is no yes or no, black or white answer to this question, when people drive squatted trucks, there is an increased risk of danger.
Depending on the angle of the squat, their visibility may be impeded. Likewise, increasing the height of your front fender by a few inches can adjust the angle your headlights are aimed, which reduces night-time visibility and can blind oncoming drivers.
In theory, squatting your truck can be done safely, but only if modified so that the suspension still has proper travel that doesn’t impact handling, etc. Unfortunately, many aftermarket parts used for squatting trucks are not entirely safe, which has led to legislation banning the idea in several states.
When modifying a car beyond a manufacturer’s recommended specifications, there is always the risk of complications.
