What is a consequence of not securing a flatbed load properly?

Not securing a flatbed load properly can lead to the load shifting during transport. When a load is not adequately secured, it may move around due to sudden stops, turns, or changes in speed, posing significant safety risks. A shifting load can affect the vehicle's balance and control, increasing the likelihood of accidents or spills on the road. Proper securing methods, such as using straps, chains, or tarps, are essential to maintain the load's position and ensure safe transportation.

The other options do not relate to the consequences of improper securing of a load. For instance, improving fuel efficiency is not a factor connected to how well a load is secured. Instead, improper securing of a load can actually result in increased drag and decreased efficiency. Additionally, a load becoming lighter or easier to access is not relevant to the dangers of improper securing—the emphasis must be on safety and stability during transit. Properly securing a load ensures not only the safety of the driver and other road users but also helps prevent damage to the cargo and the vehicle itself.
