Trailers with a GVW greater than 4500 lbs but less than ___________ and operated at __________ mph or less are not required to have brakes.

The correct choice indicates that trailers with a Gross Vehicle Weight (GVW) greater than 4500 lbs but less than 15000 lbs are not required to have brakes when operated at 30 mph or less. This guideline is established to ensure safety and regulation compliance for smaller trailers that, due to their weight and speed limitations, do not pose the same risks as heavier or faster trailers.

For a trailer with a GVW exceeding 4500 lbs but below 15000 lbs, the requirement for brakes is intended to focus on reducing unnecessary regulatory burdens on lighter trailers while still maintaining safety for all road users. Operating at 30 mph or lower means that the potential dangers associated with braking distance are minimized, hence the exemption from braking requirements in this scenario.

Understanding these weight and speed thresholds is essential for compliance with Texas regulations and keeping both the driver and other road users safe. Being familiar with such distinctions helps operators make informed choices about equipment and safety measures when towing trailers.
