What Lights Should Be Turned On When Driving in the Rain?

When driving in the rain, you should turn on the headlights, width indicator lights, and rear fog lights, using different lights depending on the amount of rain: 1. Use width indicator lights when the rain is light; 2. Use headlights or front fog lights when the rain is heavy; 3. Use rear fog lights during heavy rain. Rear fog lights should only be turned on during heavy rain because they are extremely bright and can penetrate thick fog. Additionally, when driving in the rain, it is essential to maintain a safe distance from the vehicle ahead. Wet and slippery roads can make sudden braking difficult at high speeds, so driving at a lower speed effectively allows more time for braking and helps prevent accidents. Stay away from large trucks and heavy vehicles, and slow down when passing through waterlogged areas. If the water depth exceeds half of the tire height, there is a risk of water entering the vehicle and engine, posing a threat to driving safety.
Having driven for decades, I believe turning on lights in rainy weather is crucial. First, activating the low beams is fundamental—they ensure you see the road ahead clearly without causing raindrops to reflect blinding glare. During heavy rain or thick fog, I also engage the fog lights, especially on highways, as they cut through water vapor to enhance visibility. Never use high beams; the reflection off raindrops creates a blinding whiteout, which is extremely hazardous. Make it a habit to check all lights—including taillights—before heading out; don’t wait for rain to expose a malfunction. Rain already makes roads slippery, so drive slowly and maintain distance. Your lights act as your eyes—if they’re not on, accidents become far more likely.
