How to Light a Road Flare

by Alex Wittle

Road flares are bright, burning sticks that emit a strong red or orange light. They are commonly used by emergency responders, drivers, and construction crews to signal distress, warn oncoming traffic, or mark an accident scene. Most road flares are pyrotechnic, meaning they burn using a chemical reaction. Modern and more expensive ones are usually LED-based.

Safety Precautions Before Lighting a Road Flare

Before you light a road flare, keep these tips in mind:


  1. Check surroundings. You should be in a safe area away from traffic and flammable materials like dry grass, fuel, or paper.

  2. Wear gloves if available. Some flares can produce sparks or intense heat that might burn your fingers.

  3. Keep extra flares at a distance to prevent accidental ignition.

  4. Keep an eye on the flare and surrounding area to prevent accidents.


How to Light a Road Flare


Step 1: Remove the Flare from Its Packaging

Most road flares come in a protective wrapper or case. Open it carefully and remove the flare. Be careful not to damage the ignition cap.


Step 2: Locate the Ignition Cap

One end of the flare will have a cap or a striking surface. This is the ignition point. If your flare does not have that, it might have a plastic cap that needs to be twisted off to reveal the igniter.


Step 3: Hold the Flare Properly

Grip the flare firmly in your dominant hand. Keep your fingers away from the igniter end. Point the flare slightly downward to prevent any sparks from flying toward your body.


Step 4: Strike the Igniter

  • If the flare has a strike cap, remove it and use the rough surface inside to strike the ignition tip like a match.

  • If the flare has a pull tab, hold the flare firmly and pull the tab away from your body to ignite it.

  • Some modern flares may have a twist mechanism; in this case, follow the manufacturer’s instructions.

The flare will spark before producing a steady flame. Hold it steady for a few seconds until it's burning properly. If it flickers out, try striking it again.


Step 5: Position the Flare Safely

Once the flare is burning:

  • Place it on the ground, away from your vehicle, traffic lanes, and any other flammable material.

  • If placing it on the road, make sure it’s visible to approaching drivers.

  • Do not throw or drop the flare.

Once it burns out, let it cool completely before picking it up. Place it in a non-flammable container or follow local disposal guidelines. 


How Long Do Road Flares Last?

Most standard road flares burn for 15 to 30 minutes. The burn time depends on the size and type of flare. LED road flares can last for hours or days.


How to Extinguish a Road Flare

Unlike candles, road flares do not have an off switch. You must let them burn out naturally or extinguish them safely:


  1. Let it burn out in a safe location.

  2. Submerge in water. Douse the flare in water to cool it quickly.

  3. Smother the flare with dirt or sand to cut off oxygen.


Note: Never stomp on a flare. This can cause injury.


Final Thoughts

Always handle road flares carefully and follow proper safety steps. Mishandling can lead to burns, fires, or serious injuries.
