Rain creates some of the most dangerous driving conditions on the road — hydroplaning, reduced visibility, and longer stopping distances can all catch drivers off-guard. Here's how to stay safe in wet weather.
Water reduces friction between tires and road, increasing stopping distances by 30–40% compared to dry conditions. The first 10–15 minutes of rain are often the most dangerous — water mixes with accumulated road oil and dust to create an extremely slippery surface before the rain washes it away. Visibility is also reduced, especially at night when wet roads create glare from headlights.
The posted speed limit is for ideal conditions. In rain, reduce your speed by 5–10 mph on highways and add at least 50% to your normal following distance. The combination of longer stopping distances and reduced visibility means you need more time and space to react safely to what's ahead.
Hydroplaning occurs when tires can't channel water fast enough to maintain road contact. It typically happens above 35 mph in standing water or heavy rain. Prevention: maintain adequate tread depth (worn tires are much more vulnerable), reduce speed, avoid puddles and wheel ruts, and keep tires properly inflated. If you feel the car begin to float, ease off the gas smoothly — do not brake suddenly.
Turn on your headlights in rain — in many states it's required by law, and it improves your visibility to other drivers significantly. Ensure your wiper blades are in good condition and replace them annually (or when they leave streaks). Avoid using cruise control in wet conditions — it can cause your car to accelerate if a tire hydroplanes.
