What to Do If the Hazard Lights Keep Flashing?

There is a hazard light button on the car's dashboard, marked with a red triangle. Press it once to turn on and press it again to turn off. If it doesn't work no matter how you press it, then check if the switch is functioning properly or if there is a circuit short. It's best to drive to a repair shop for inspection. Hazard lights are also called emergency indicators. As the name suggests, when you see the car in front turning on its hazard lights, it must be in a situation where it cannot move, whether due to a breakdown or waiting for the police after an accident. This is to alert the cars behind that there is a stationary vehicle ahead and to avoid collision. However, if you turn on the hazard lights while continuing to drive just because it's raining, you really need to revisit the theoretical knowledge of your driver's license! During heavy rain, visibility is already very low. If you turn on your hazard lights at this time, the cars behind will think your vehicle has a problem, and some may slow down or even brake suddenly. In such rainy conditions, once one car brakes, it's very easy to cause a rear-end collision! Moreover, traffic authorities have regulations stating that turning on hazard lights in very low visibility conditions will result in a 1-point deduction and a fine of 20-200 yuan. So, please remember, never turn on your hazard lights during heavy rain!
Last time I was driving, the hazard lights kept flashing on their own, which really annoyed me. This kind of situation is mostly an electrical issue. I quickly checked if the switch was stuck and not bouncing back—it was fine. Then I checked the fuse box, using my phone flashlight to look at the corresponding fuse number—sure enough, it was burnt black. Actually, the most common causes are a blown fuse or poor switch contact, and it could also be a door not closed properly because some car models have very sensitive sensors. I recommend first parking the car safely, popping the hood to locate the fuse box, and replacing the corresponding fuse according to the manual. If the lights still flash, then you’ll need to check the wiring—it might be a short circuit from the audio system modification where the wires got pinched. If you still can’t fix it, just take it to a repair shop. Don’t be like me that time on the highway when the lights suddenly started flashing and I almost got rear-ended.
