The MB-2 maximum weight on grades up to 2.0% is which value?

Explanation:
When towing on a slope, the weight you can safely move depends on how steep the grade is. The MB-2 rating is the limit used for controlling that. On grades up to 2.0 percent, the system is rated to safely handle up to 450,000 pounds. This limit reflects the combination of engine torque, braking capability, and tire traction available to hold and stop the load on that incline. If the grade were steeper or you tried to haul more than 450,000 pounds, braking distance and control could be compromised, which is why higher weights aren’t permitted for that grade. Therefore, 450,000 pounds is the appropriate maximum for grades up to 2.0 percent.
