What is the first action to take when an apparatus goes into a skid?

When an apparatus goes into a skid, the appropriate first action is to release the brakes. This is because applying the brakes during a skid can worsen the instability of the vehicle, making it more difficult to regain control. Releasing the brakes allows the wheels to rotate freely, which can help the driver regain traction on the road surface.

Once the brakes are released, the driver can then steer in the direction of the skid to help align the vehicle and bring it back under control. This technique works as it allows for the redistribution of weight and can help the vehicle regain grip. Additionally, pumping the brakes might also introduce further instability and confusion when trying to regain control. Thus, releasing the brakes is the critical first step to managing a vehicle that's skidding.
