What is the maximum drive axle weight allowed during an ASM smog test on a 3/4 ton truck?

Explanation:
The maximum drive axle load is set to five thousand pounds to keep the test within the dynamometer’s rated capacity and to ensure consistent, valid emissions measurements. This cap prevents overloading the rollers and keeps the engine load during testing in a range that the ASM procedure is designed to evaluate. Using a higher load could damage equipment or skew results, while a lower load wouldn’t meet the standard test conditions. So, five thousand pounds is the limit for the drive axle during this test.
