What is the total weight of the tractor when the steering axle is loaded to 12,420 lbs and tandem axles are at 33,980 lbs?

To find the total weight of the tractor, you simply need to add the weight of the steering axle to the weight of the tandem axles. In this case, the steering axle is loaded to 12,420 lbs and the tandem axles are at 33,980 lbs.

Calculating the total weight involves the following addition:

Total Weight = Weight of Steering Axle + Weight of Tandem Axles

Total Weight = 12,420 lbs + 33,980 lbs

Total Weight = 46,400 lbs

This results in a total weight of 46,400 lbs, confirming that this is the correct answer.

Understanding this principle is crucial in truck weight management and compliance with regulations, as exceeding weight limits can lead to fines and safety issues on the road.
