If you place a very heavy load on one side of a vehicle, what may happen?
- It may cause flat spots on the tires.
- It may increase the risk of a rollover.
- It may cause the brakes to lock the wheels on the underloaded side.
- All of the above may happen. ✓
Answer: D. All of the above may happen.
Placing a very heavy load on one side can cause all of these things: flat spots on the tires, a higher rollover risk, and brakes locking the wheels on the underloaded side.
Why this is the answer
The handbook warns against putting a very heavy load on one side of the vehicle. It says that overloads the springs and tires on the cargo side, and that the brakes may lock the wheels on the under-loaded side, which can make the tires skid on wet pavement. It also says loading in this unbalanced way may cause flat spots on the tires. A load that sits high and off-center also makes the vehicle less stable, so the rollover risk goes up.
Why the other answers are wrong
- A. It may cause flat spots on the tires. — Flat spots are real, but they are only one of the effects the handbook lists, so this choice is incomplete.
- B. It may increase the risk of a rollover. — Rollover risk is a genuine concern with an unbalanced load, but on its own it leaves out the tire and brake problems the handbook describes.
- C. It may cause the brakes to lock the wheels on the underloaded side. — Brake lock-up on the underloaded side does happen, but it is only one part of what the handbook says about one-sided loading.
Remember it
Picture the weight all on one side: the tires there carry the stress, the tires on the light side lose grip under braking, and the whole truck leans.
