If hydroplaning occurs while driving an ambulance, what should the driver do?

When hydroplaning occurs, the vehicle's tires lose contact with the road surface due to a layer of water, resulting in a loss of control. The appropriate response in this situation is to gradually slow down without jamming on the brakes. This action allows the driver to reduce speed in a controlled manner, enabling the tires to regain traction on the road.

Sudden braking can lead to further loss of control, as locking up the wheels can cause the vehicle to skid. Stepping on the accelerator in an attempt to speed up is also ineffective because it exacerbates the hydroplaning effect, making it even harder to regain control. Additionally, sharp steering maneuvers can further destabilize the vehicle, increasing the likelihood of a spin or losing control completely.

Thus, gradually slowing down while refraining from sudden inputs allows the driver to regain control safely and effectively.
