Step-by-step explanation:
The maximum carry weight for tandem axles is 34,000 pounds in the United States. This equals to 17 tons as one ton is equivalent to 2,000 pounds. When considering tandem axles on trucks, the weight limits are established to ensure safety and to prevent damage to roadways. Each of the options provided in the question does not match the federally regulated limit. However, it is important to note that actual weight limits can also vary by state and by the specifics of the road system, so always check local regulations.
