Hawaii Drivers Permit Practice Test

A trailer that weighs more than half of the towing vehicle's weight is required to have both brakes and breakaway protection. This regulation ensures the safety of both the towing vehicle and the trailer, as well as other road users.

Brakes on the trailer are essential because they provide the necessary stopping power, especially when descending inclines or during sudden stops. The braking system allows the trailer to reduce its speed in conjunction with the towing vehicle, preventing accidents and loss of control.

Breakaway protection is also crucial. This safety mechanism ensures that if the trailer becomes detached from the towing vehicle, it will automatically engage the brakes. This feature minimizes the risk of the trailer rolling away uncontrolled, which could pose significant dangers to other drivers, pedestrians, and property.

Having both brakes and breakaway protection is essential for maintaining control of the trailer and ensuring safe towing practices, especially when the trailer's weight is substantial in relation to the towing vehicle.
