Under what condition can vehicles carrying farm products exceed the maximum width limitation?

Vehicles carrying farm products can exceed the maximum width limitation during good visibility conditions because such allowances are often made to facilitate the transportation of agricultural goods during times when it is deemed safe for both the vehicles and other road users. This is particularly important for farm operations, as it helps ensure that products are moved efficiently, especially during harvest seasons.

Safe visibility means that drivers can see and react to other vehicles and road conditions adequately, which reduces the risk of accidents. Trying to transport oversized farm products during poor visibility conditions, such as at night or during inclement weather, could lead to dangerous situations on the road. Thus, the regulation supports safe transport while balancing the need to accommodate farming operations within a structured framework.
