At what time should you check your cargo's weight?

Answer: C — After every 150 miles or after three hours

Checking your cargo's weight after every 150 miles or after three hours is crucial for maintaining safety and compliance with weight restrictions. This practice ensures that the vehicle does not exceed federal and state weight limits, which can vary depending on the type of roadway and location. Additionally, weight changes can occur during transit due to cargo shifting or fuel consumption. Monitoring the weight at regular intervals helps prevent potential issues such as handling difficulties, increased wear on tires and brakes, and legal penalties for being overweight. Although checking the cargo's weight before leaving home is a good initial step, it does not account for any changes that may occur during travel. Similarly, while checking after every fuel stop seems reasonable, it may not be frequent enough to catch issues that arise in between stops. Checking at every traffic signal is not practical or necessary and would likely cause delays and safety concerns. Therefore, the recommended frequency of checking cargo weight after 150 miles or three hours strikes an appropriate balance between thoroughness and practicality in ensuring safe transportation.
