Having registration papers for trucks at all times is essential because they provide critical information regarding the vehicle's specifications, particularly its weight when empty and its maximum registered hauling capacity. This information is crucial for compliance with state and federal regulations, which govern the weight that can be transported over roads to ensure safety and avoid damage to infrastructure.

Regulations typically require drivers to adhere to weight limits to prevent accidents and wear on roads and bridges. Knowing the truck's empty weight and its registered hauling capacity helps drivers load their trucks safely and responsibly, ensuring they do not exceed weight limits that could lead to fines or penalties. It also aids in emergency situations where precise vehicle information is necessary for law enforcement or roadside inspections.

In the context of the other options, while understanding the truck model, its weight when loaded, or verifying insurance might be relevant, they do not encompass the core reasons for maintaining registration papers on hand concerning legal regulations and weight compliance.
