Which of the following is part of the safety features required by Texas law?

In Texas, safety glass is a required feature for vehicles to ensure that they provide a higher level of safety in the event of an accident. Safety glass, often made of tempered or laminated glass, is designed to minimize the risk of injury to passengers. It reduces the likelihood of shattering upon impact, which can cause serious injuries from glass shards. Requirements for safety glass reflect the state's commitment to enhancing vehicle safety standards and protecting occupants in various driving conditions.

Other options, while they may enhance comfort or aesthetics, do not contribute to the core safety features mandated by law.
