What is the correct action if your vehicle starts to hydroplane on a rain-slicked highway?

1. Slam hard on the brake pedal and pull the handbrake immediately
2. Ease off the accelerator smoothly, hold the steering wheel straight and steady, and avoid abrupt braking or sharp turns until traction is restored
3. Accelerate rapidly to spin the tires and cut through the water film
4. Turn the steering wheel vigorously from side to side
