Question

Difficulty: MediumWeight Distribution and Securing Loads

In an estate car or hatchback, placing heavy items flat on the boot floor directly against the back of the rear seats helps maintain vehicle stability and prevents cargo from gaining forward momentum during emergency braking.

Answer: Answer

Answer

True
The statement is true because placing heavy luggage flat on the boot floor lowers the centre of gravity to preserve handling, and resting it directly against the rear seats eliminates space for the load to gain destructive momentum under heavy braking.

Step-by-Step Solution

1
Assess the effect of vertical load placement on the vehicle's centre of gravity
Placing heavy items flat on the floor keeps the centre of gravity low, which stabilises vehicle handling and minimizes roll during cornering and braking.
A high centre of gravity destabilises the vehicle and significantly increases the risk of skidding or losing control.
2
Evaluate the mechanical restraint of placing cargo flush against the rear seat back
Positioning heavy cargo directly against the rear seat back prevents it from travelling forward when the vehicle stops abruptly.
Any gap between the cargo and a rigid partition allows the cargo to accelerate relative to the car interior during emergency braking, multiplying the force exerted against the seat.
