Topic overview

Darkness and bad weather are two of the hardest conditions to drive in, and this section shows you how to handle both. At night your ability to see is greatly reduced, and much of your reaction time depends on vision — so the golden rule is simple: never outrun your headlights. Slow down enough that you can always stop within the distance you can clearly see.

Rain, fog, and ice each call for a different response. Wet pavement can be as treacherous as ice, and it's most slippery right when rain starts and mixes with oil on the road. Use low beams in fog — high beams just reflect back at you — and remember that bridges and overpasses freeze before the rest of the road. If you start to hydroplane or skid, ease off the gas and steer gently; don't slam the brakes.

Flooding is the deadliest weather-related hazard on the road, and it takes surprisingly little water to sweep a vehicle away. The rule to remember is "Turn Around, Don't Drown" — never drive into a flooded roadway. This section also covers strong winds, sun glare, getting unstuck from mud or snow, and how to brake correctly on ice with and without antilock brakes. Clear all your windows of snow and ice before you set off.

Should I use high beams in fog?

No. In fog, mist, or smoke, high beams reflect off the moisture and bounce the light back into your eyes, making it harder to see. Always use low beams instead. In fact, Tennessee law requires low-beam headlights when you drive through dense fog, heavy rain, or snow, even in daytime.

What should I do if my car starts to hydroplane?

Slow down gradually by easing your foot off the gas — do not slam on the brakes. Hydroplaning happens when tires ride up on a film of water, so steering control may be reduced or lost and stopping distances can triple. It's more common at higher speeds, which is exactly why reducing speed in the rain matters so much.

How deep does flood water have to be before it's dangerous?

Far less than most people think. Just six inches of fast-moving water can knock a person off their feet, and most cars can be swept away in 18 to 24 inches. Because you often can't judge the depth or the current, the only safe choice is to turn around — never drive into a flooded roadway. If your vehicle stalls in floodwater, leave it and get to higher ground.
