What action is advisable in emergency situations with a rear-wheel skid?

In emergency situations involving a rear-wheel skid, the advisable action is to release the accelerator and clutch. When the rear wheels lose traction, the vehicle begins to skid, and maintaining power to the wheels can exacerbate the loss of control. By releasing the accelerator, you allow the wheels to regain traction, which is crucial for recovering control of the vehicle.

Additionally, by disengaging the clutch, the engine is separated from the wheels, preventing any additional power from being sent to the rear wheels. This action helps stabilize the vehicle and enables better steering control. As the driver regains control, they can then steer in the direction they want to go, helping to bring the vehicle back on its intended path.

Other actions like turning the wheel left, adjusting brake pressure gradually, or shifting into a lower gear might not directly address the immediate problem of a rear-wheel skid. These actions could potentially worsen the situation by causing further loss of control or by locking up the wheels during the attempt to brake or gear down. It's crucial to focus on regaining traction and control through the correct initial steps.
