In which scenario does an all-wheel skid occur?

• A. During heavy acceleration
• B. All wheels lock due to excessive braking
• C. While driving on uneven terrain
• D. When steering sharply

Answer: (B)

An all-wheel skid occurs specifically when all wheels lock due to excessive braking. In this scenario, the vehicle loses traction entirely because the brakes are applied so forcefully that the tires cannot maintain contact with the road surface. This results in the tires sliding across the pavement, leading to a loss of control over the vehicle as none of the tires can grip effectively. While other scenarios can lead to skids or traction loss, they do not involve all wheels simultaneously locking. For instance, heavy acceleration typically causes the rear wheels to spin if they lose grip, which is different from an all-wheel skid situation. Similarly, driving on uneven terrain may affect traction but does not inherently cause all wheels to lock. Steering sharply can also lead to a skid, but typically that affects traction in a controlled manner without locking the wheels completely. Therefore, locking all wheels during excessive braking is the defining factor for an all-wheel skid.
