What is the requirement for trailer emergency brakes on trailers manufactured after June 01, 1970?

For trailers manufactured after June 01, 1970, the requirement for emergency brakes is that they must remain applied for 15 minutes after a breakaway. This regulation is crucial for ensuring safety, as it provides a safeguard in case the trailer becomes disconnected from the towing vehicle. The 15-minute timeframe allows for a sufficient duration to bring the trailer to a stop, minimizing risks to other road users.

The automatic engagement of brakes is important, but the specificity of the time duration is what sets the requirement apart. The standard for trailers manufactured prior to this date differs significantly, as those vehicles did not have the same safety mandates. Trailers manufactured after the specified date are therefore subject to more rigorous standards which reflect advancements in safety technology and practices. Additionally, not all trailers are exempt from these requirements; thus, stating that they are not required does not align with the safety measures instituted for modern trailer designs.
