The Complete Guide to Using Hazard Lights: Tips from Gear Headz Auto


We’ve all seen it: a car parked on the side of the road with its hazard lights flashing. But do you know when and how to use these lights correctly? Gear Headz Auto brings you this comprehensive guide to help you understand the importance of hazard lights and how to use them effectively.

What Are Hazard Lights?

Hazard lights are a vehicle’s flashing warning lights that indicate to other drivers that the vehicle is experiencing a problem. They are usually activated by pressing a button on the dashboard, often marked with a red triangle.

When Should You Use Hazard Lights?

Emergency Situations

Use your hazard lights when your vehicle becomes a temporary obstruction on the road. This could be due to a flat tire, engine failure, or an accident.

Roadside Assistance

If you’re waiting for roadside assistance or a tow truck, it’s advisable to turn on your hazard lights to warn other drivers that your vehicle is stationary.

Heavy Traffic

In some states, it’s permissible to use hazard lights to indicate that you’re driving at a significantly reduced speed in heavy traffic.

When Not to Use Hazard Lights

Bad Weather

Contrary to popular belief, using hazard lights in heavy rain or fog can actually reduce visibility and confuse other drivers.


Never use hazard lights to justify illegal parking. It’s misleading and can result in a fine.

Driving in a Convoy

Using hazard lights while driving in a group can make it difficult for other drivers to understand your intentions, like turning or changing lanes.

State-Specific Laws

Laws regarding the use of hazard lights can vary by state. Always check your state’s DMV or DOT guidelines to ensure you’re using them correctly.


Understanding the proper use of hazard lights is crucial for your safety and that of other road users. Trust Gear Headz Auto for more tips and services to keep you safe on the road.
