You are in your car towing a fully loaded trailer which has no brakes. What is correct?

When towing a fully loaded trailer without its own brakes, your vehicle becomes heavier and harder to stop. This increases the braking distance because your car's brakes have to work harder to slow down both the car and the trailer. However, your reaction distance—the distance you travel from the moment you notice a hazard to the moment you start braking—does not change, as that depends only on your attention and reaction time. The overall stopping distance will not reduce; it will also increase due to the added weight and the lack of trailer brakes. So, only the statement about increased braking distance is correct. Remember, always allow for a greater stopping distance when driving with a heavy, unbraked trailer.
