Difficulty: EasyEffects on Vehicle Handling and Braking

Carrying heavy cargo on an external roof rack raises a vehicle's centre of gravity, which increases body roll and reduces stability when cornering.

Answer: Answer

Answer

True — adding weight to a roof rack elevates the vehicle's centre of gravity, amplifying body roll and reducing handling stability during cornering.
Loading items onto a roof rack moves the vehicle's centre of gravity higher above the ground. This upward shift increases the leverage of lateral forces during turns, resulting in more pronounced body lean and compromised handling.

Step-by-Step Solution

1
Analyze how weight position affects the vehicle's centre of gravity
Loading items high up onto a roof rack raises the vehicle's overall centre of gravity.
Mass distributed farther away from the road surface shifts the balance point upwards.
2
Evaluate the mechanical consequence of an elevated centre of gravity during steering
Cornering forces produce a stronger tipping leverage, leading to increased body roll and reduced road stability.
A higher centre of gravity causes the vehicle to lean more heavily into turns, compromising handling precision and grip.
