How can you determine that a truck is overloaded?

You answered correctly. To determine if a truck is overloaded, you can weigh the loaded vehicle or use built-in axle weight measuring devices. These methods provide accurate information about the truck's total and axle loads. A brake test, however, does not reliably indicate if a truck is overloaded because it only checks braking performance, not the vehicle's actual weight. In future questions, remember that only weighing methods or official measuring devices can confirm an overload.
