When driving a passenger coach in heavy rain or on wet roads, how should the driver adapt their driving style for passenger safety?

1. Accelerate to 120 km/h to pass through the storm faster
2. Increase following distance significantly (at least 4–5 seconds), reduce cruising speed, avoid sudden steering inputs, engage retarder with caution on slippery surfaces, and brake smoothly and early
3. Turn off windshield wipers to save battery power
4. Ask passengers to lean toward the right side in curves
