Playing on Silverrun map, I noticed what oncoming vehicles stop in their line when I drive with UAL-enabled trailer.
Effect disappear if I disable UAL.
My version is what loading|unloading zones make trailer's collision box a lot wider.
It's bug or property?
Screenshots (with devcontrols enabled and F5 pressed once - display of collision boxes I think):
