Which of the following is prohibited equipment on passenger cars in Texas?

In Texas, the use of a muffler cutout on passenger cars is prohibited because it can significantly increase noise pollution and may result in emissions that do not meet state standards. Muffler cutouts allow exhaust gases to bypass the muffler, which can lead to excessive noise and potential violations of local ordinances concerning vehicle noise levels. This regulation exists to promote a safer and more pleasant environment for all road users, as well as to maintain vehicle standards that contribute to public health and safety.

In contrast, reflective mirrors, turn signals, and windshield wipers are essential safety features that are required on all passenger vehicles. Reflective mirrors are crucial for visibility and help drivers maintain awareness of their surroundings. Turn signals are necessary for communicating intentions to other drivers, ensuring safe lane changes and turns. Windshield wipers are vital for maintaining clear visibility during adverse weather conditions, which is essential for safe driving.
