What is the maximum gross weight at which surge or intra brake systems may be used on trailers and semi-trailers?

The maximum gross weight at which surge or intra brake systems may be utilized on trailers and semi-trailers is 15,000 pounds or less. Surge brakes, also known as hydraulic surge brakes, operate based on the momentum of the trailer when it is towed by a vehicle. They engage the braking mechanism of the trailer automatically as the trailer pushes against the towing vehicle during braking.

The guideline limiting the weight to 15,000 pounds ensures that the braking system remains effective and safe. At weights exceeding this threshold, the capacity and functionality of surge brakes could be diminished, potentially leading to impaired control and increased stopping distances. This weight limit is set for the safety of both the driver and other road users, as well as to comply with existing regulations governing trailer braking systems in Texas and generally across various jurisdictions.

Understanding this weight limitation is important when hauling loads, as adhering to these regulations not only ensures safety but also compliance with state laws. This clarifies why option B is the correct choice, as it aligns with the established regulations regarding surge braking systems.
