Why can’t I go under a y-post?

A y-post is a type of fence post that is designed to support a fence line. It is typically made of wood, metal, or composite material. The Y-post has an angled shape that provides strength and stability to the fence line, and it is designed to be driven into the ground with a post driver.

The reason why you cannot go under a y-post is because it is designed to be driven into the ground. If you try to go under it, you could risk damaging the post or the fence line, as well as potentially injuring yourself. Additionally, the post is typically placed in the ground at an angle, which creates an obstacle that would be difficult to maneuver around.
