At what point is a vehicle load more likely to shift?

A vehicle load is more likely to shift when cornering due to the forces acting upon the vehicle during a turn. When you turn, centrifugal force tries to push the load outward, which can result in it moving away from its original position. This is especially true if the load is not secured properly.

During cornering, the lateral forces exerted can cause loose cargo or improperly distributed weight to slide or tip over. This is a critical consideration for both safety and vehicle handling, as a shifting load can affect the vehicle's balance, stability, and braking capability.

Driving straight typically doesn't involve the same lateral forces, and while rapid acceleration can cause initial movement of a load, it’s the combination of speed and direction change during cornering that significantly increases the risk of load shifting. Making a U-turn may involve cornering, but it's the continuous lateral movement in a turn that poses the greatest risk of a load shifting position unexpectedly.
