When hauling a load heavier than allowed by law, what must be obtained?

When hauling a load that exceeds legal weight limits, obtaining a special permit is essential. This permit is specifically designed to allow vehicles to carry loads that are heavier than the standard legal restrictions. The special permit ensures that the transportation complies with regulatory requirements, maintains safety on the roads, and allows for potential infrastructure wear and tear considerations.

Special permits can include stipulations about the route to take, specific times for transport, and conditions that must be met to ensure safety and compliance. This is crucial for mitigating risks and ensuring that both the vehicle and its cargo do not pose safety hazards to the driver, other road users, or the infrastructure.

The other options do not provide the necessary legal access to transport overweight loads. Standard permits and weight declarations serve different purposes and do not equate to the specific allowances granted by a special permit. Therefore, securing a special permit is the correct action to take when dealing with heavier loads.
