LIABILITY/CIVIL: Provides relative to liability for commercial motor vehicles

This bill modifies liability rules for commercial motor vehicles by stating that owners are not required to install optional equipment. It further specifies that the lack of such equipment cannot be used as evidence to prove the owner was negligent. These changes directly affect trucking companies and vehicle owners by limiting the circumstances under which they can be held responsible for missing non-mandatory features. The amendment aims to clarify legal duties regarding vehicle modifications without mandating any specific safety upgrades.
