A trailer with a GVW of more than 4500 lbs but less than 15000 lbs traveling in excess of how many mph are required to have brakes?

A trailer with a Gross Vehicle Weight (GVW) of more than 4500 lbs but less than 15000 lbs is required to have brakes if it is traveling in excess of 30 mph. This requirement is important for safety reasons, as trailers of this weight class can become difficult to control and stop, especially at higher speeds. The braking system helps ensure that the trailer can respond effectively to the driver's actions and reduce stopping distances, which is crucial in preventing accidents.

In Texas, as per regulations, trailers that reach certain weights are seen as needing enhanced safety features, such as brakes, to manage the additional mass and momentum they carry while in motion. The threshold of 30 mph specifically indicates a point at which the dynamics of the vehicle-trailer combination demand better braking performance.

The other speed thresholds are not applicable because they do not align with the established safety guidelines for trailers in this weight range, which are designed to ensure both compliance with laws and the safety of road users.
