Which factors lengthen your braking distance?

You answered everything correctly. Your braking distance increases if you are towing a trailer without its own brakes because your car has to slow down both its own weight and the extra weight of the trailer, which requires more distance. Wet or slippery roads reduce tire grip, meaning it takes longer for your car to come to a stop. Driving downhill also increases braking distance because gravity pulls your vehicle forward, so you need more distance to slow down. For questions about braking distance, always consider the vehicle’s load, road conditions, and whether you are going uphill or downhill.
