Which factor should you base your safe grade speed on?

• A. Your vehicle and its cargo
• B. The color of the vehicle
• C. The time since last service
• D. The type of music playing

Answer: (A)

Base your safe grade speed on the vehicle and its cargo. The truck’s weight, how the load is distributed, braking capability, traction, and how the cargo might shift all determine how quickly you can descend a grade safely. Heavier loads or ones that can shift easily require slower speeds and more distance to stop, especially on curves or slippery surfaces. Weather and road conditions also matter, but the starting point is what the vehicle and its load can handle.

The color of the vehicle doesn’t affect performance, and while the time since the last service can influence safety if maintenance is overdue, it isn’t the factor you use to set grade speed. The type of music playing has no impact on driving safety.
