What is the maximum tandem axle weight for trucks?

Answer: B — 17,000 lbs per axle

The maximum tandem axle weight for trucks is 17,000 lbs per axle. This means that the total weight for two axles together cannot exceed 34,000 lbs. Option A (15,000 lbs per axle) is too low and would only allow a maximum total weight of 30,000 lbs for two axles. Option C (20,000 lbs per axle) and D (25,000 lbs per axle) are both too high and would exceed the maximum weight limit for tandem axles. Therefore, option B is the correct answer as it falls within the specified weight limit for tandem axles.
