Wildfire smoke and evacuation: how to drive out safely
How to prepare to leave fast, drive through smoke and survive if fire traps your car
Wildfires can move faster than people expect. Wind can push flames and embers across miles in a short time. Roads out of foothill and forest towns are often few and narrow. In recent fires, jammed roads and abandoned cars have trapped people trying to flee.
Smoke adds another danger. It can cut visibility to a few feet and spread hundreds of miles from the fire. Federal crash data group smoke with fog, blowing dust and blowing snow as low visibility conditions. Those conditions are linked to nearly 500 traffic deaths a year [1]. This guide covers how to prepare, when to go and what to do if the worst happens.
Get ready before fire season
Fire agencies use a simple plan called Ready, Set, Go [4]. The “ready” part happens long before a fire.
- Sign up for local alerts from your county or city. Do not rely on one phone app.
- Know two ways out of your neighborhood. Drive them so you know them.
- Pack a go bag for each person: water, masks, medicines, phone chargers, documents, glasses and a change of clothes.
- Keep the car ready. During fire season, keep the tank at least half full, or an EV well charged.
- Plan for pets and people who need help, such as older neighbors.
When a fire is near: get set
- Park facing out, toward the street, so you can leave fast.
- Load the car with your go bag and pets’ supplies.
- Close windows and doors in the car and the house.
- Keep your phone charged and the radio on.
- Wear long sleeves, long pants and sturdy shoes made of cotton or wool.
Go: leave early
Leave as soon as officials say to, or sooner if you feel unsafe. Do not wait for an order if fire is close and roads are still open. Leaving early lets you drive before smoke thickens and traffic jams form.
While driving:
- Follow the evacuation route officials give. Do not take unfamiliar shortcuts into canyons or dead ends.
- Drive with headlights on, even in daytime.
- Do not stop to watch or film. Keep traffic moving.
- Make room for fire engines and emergency crews.
- Watch for fallen trees, power lines, animals and people on foot.
Driving through smoke
Smoke can turn day into night in minutes.
- Slow down and leave extra room. You may have very little warning of stopped traffic.
- Use low beams. High beams reflect off smoke and make it harder to see.
- Close windows and set the air to recirculate so less smoke enters the car.
- Use fog lines and lane markings to stay on the road.
- If you cannot see, pull as far off the road as you can, away from brush, and turn on hazard lights.
The EPA’s AirNow Fire and Smoke Map shows current smoke and air quality, so you can check before you drive [2]. People with asthma, heart disease or lung problems should limit time in smoke.
If fire traps you in your car
Getting out early is the goal. But if fire blocks your way, these steps, recommended by fire safety experts, can save your life [3]:
1. If a sturdy building is nearby, go inside it. Buildings protect better than cars.
2. If not, stay in your car. Do not try to run through the fire on foot.
3. Park in a spot with little or no vegetation, such as a road cut, a gravel lot or an area that has already burned.
4. Turn on your headlights and hazard lights so others can see you in the smoke.
5. Close all windows and doors. Shut the air vents and turn off the air conditioning.
6. Get down below the windows. Cover yourself with a wool blanket or coat and lie on the floor.
7. Stay in the car while the fire front passes. It will get hot and smoky. The car gives you some protection from the heat.
8. When the fire has passed and it has cooled outside, get out and move to an area that has already burned.
Warning: Never drive into thick smoke or flames to reach home or a pet. Call 911 and give your exact location if you are trapped.
Checklist: fire season car kit
Checklist from Safety Behind the Wheel Foundation

Frequently asked questions
Should I wear a mask while driving?
Closing windows and using recirculation helps most. If you must drive in heavy smoke for a long time, an N95 mask can reduce what you breathe in. Cloth masks do little against smoke.
Can I drive back to get my belongings?
No. Do not go back until officials say the area is safe. Fires can shift quickly.
Will my car catch fire if I drive past flames?
It is possible. Tires, plastic and leaking fuel can ignite. That is why leaving early and following official routes is so important.
