Do not turn on your hazard lights during heavy rain under any circumstances.

Turning on Hazard Lights During Heavy Rain Can Be Dangerous to Other Drivers

Using hazard lights in heavy rain can impair the vision of drivers behind you. The continuous flashing light can cause visual fatigue and make it difficult to judge distance, especially if multiple vehicles turn on their hazard lights at the same time. This can lead to confusion—other drivers may not know if you’re turning, changing lanes, or experiencing a real emergency.

✅ Hazard lights should only be used in emergency situations when your vehicle must stop.

• If your car breaks down and is stationary, you must park it without obstructing traffic and turn on the hazard lights (*as stated in the Land Traffic Act B.E. 2522, Section 56).
• If you must stop suddenly due to an obstacle or accident ahead, you may use your hazard lights to warn vehicles behind.

🚫 Do not use hazard lights in the rain!

• When visibility is poor due to rain, reduce speed and turn on your headlights along with fog lights.
• If visibility is so low that you cannot see the road ahead, find a safe place to pull over and then turn on your hazard lights.

Hazard lights must only be used to increase safety for yourself and fellow road users.
