What may result from insufficient weight on the front axles?

Insufficient weight on the front axles can lead to a lack of traction in the front of the vehicle. Traction is essential for steering control and stability, especially during turns or on slippery surfaces. When the front axles do not have enough weight, the tires may not make adequate contact with the road, reducing grip. This can make it difficult to control the vehicle, especially when navigating sharp curves or during emergency maneuvers.

Additionally, while other options may touch upon aspects like fuel efficiency or speed maintenance, they do not hold relevance in the context of how weight distribution affects front axle performance. Proper weight on the front axle is crucial for maintaining adequate traction, which directly impacts safety and handling of the vehicle.
