The maximum gross weight allowed for trailers that can use surge or intra brake systems is indeed 15,000 pounds. This requirement is set to ensure that vehicles using these braking systems can operate safely and effectively without exceeding the designed limits of the braking technology. Surge and intra brakes are designed to handle specific load dynamics, and once the weight exceeds this threshold, it may not adequately respond to braking demands or could compromise safety during operation. Therefore, staying within this weight limit is crucial for maintaining the integrity of the braking system and ensuring compliance with safety regulations in commercial vehicle operation.
