How to Drive in Heavy Rain at Night

Driving through heavy rain at night is the kind of situation where one wrong move turns into a hospital visit. I've done it for 15 years without an accident, and it comes down to four habits.

The night I braked at a man I couldn't see

Rain at night already cuts your visibility. Add an oncoming car with its high beams on, and for a few seconds you have no vision at all.

I was driving home in a downpour. I had already dropped my speed. That's my habit. Then an oncoming vehicle hit me with its high beams, and everything past my own hood went white. I couldn't see the lane, the shoulder, or the road.

But I felt something. Not saw. Felt. A shape moving at the far edge of where my headlights reached. My eyes had registered nothing for those seconds. Something else did.

I braked harder. My vision came back a moment later. There was a man crossing the street, about fifteen feet in front of me.

I checked the mirror while I braked, making sure the car behind me wasn't about to rear-end me.

That night taught me the order of things. Following distance matters. The speed you're carrying matters more, because speed is the only thing you can still take off the table. Everything else is already too late.

1. Slow down before you think you need to

By the time your tires feel loose, you're already going too fast. In heavy rain, drop 10 to 15 mph below the posted limit, and more if water is pooling on the road. Speed limits are written for dry pavement and daylight, not a downpour at midnight.

That night I had already slowed down once before anything happened. When something felt wrong, I slowed again. The second reduction is the one that mattered. You can't always see what's ahead, but you can always leave yourself the room to stop.

2. When oncoming high beams blind you

You can't control what other drivers do with their lights. You can control the two or three seconds you spend unable to see.

Don't stare into the light. Look down and to the right. The white line on the shoulder is still there when everything else is white. It keeps your eyes anchored and pulls the beam out of the center of your vision.

Slow down immediately, without waiting to see why. You don't need to know what's in the blind spot in order to slow down for it.

Trust the feeling that something is there. I never actually saw the man until my vision came back. My eyes were useless for those seconds. Something else flagged it. When that happens, act on it instead of waiting for proof.

3. Double your following distance, then add more at night

Wet brakes need more room to stop. The two-second rule becomes four seconds in heavy rain, and five at night, when judging distance is harder. Pick a fixed point ahead, like a sign or a bridge. When the car in front passes it, start counting. If you reach it before four, back off.

What's in front of you is only half of it. Watch the mirror too. When you brake hard in the rain, the car behind you needs the same extra room, and it may not have left any. Knowing what was behind me is what let me brake that hard without turning one problem into two.

4. What to do when your car starts to hydroplane

Hydroplaning is when your tires ride up on a film of water and lose contact with the road. You'll feel the steering go light, the engine rev, and the car drift. Do two things, in this order: take your foot off the gas, and keep the wheel straight. No braking, no jerking the wheel. The tires regain grip in a second or two.

These four habits will get you home on the worst nights. But they're one slice of a bigger system: reading the drivers around you, holding your line under pressure, dealing with the aggressive driver in your mirror.
