What to Do If Caught Driving During a Tornado
How should you react if dark skies and rotating clouds appear while you’re behind the wheel? Never try to outrun a tornado in your vehicle. Tornadoes can travel at speeds up to 70 mph and change direction unpredictably.
If you spot a tornado while driving, pull over immediately. When possible, seek shelter in a sturdy building. If no building is accessible, exit your vehicle and lie flat in a low ditch away from your car, covering your head with your hands.
Don’t shelter under highway overpasses, as these areas can create wind tunnels that intensify dangerous debris. Stay away from trees, which can fall or become projectiles. Keep your seat belt fastened until you’ve completely stopped your vehicle and are ready to evacuate.
Safety Strategies for Escaping a Tornado in Your Vehicle
Three critical decisions can determine your survival when facing a tornado while in your vehicle. First, if you spot a tornado early enough and roads permit, drive at right angles away from the storm’s path at highway speeds.
Second, if escape isn’t possible and sturdy shelter exists nearby, abandon your vehicle and seek protection inside.
As a last resort, if you’re trapped with no shelter, pull over, turn on your hazard lights, and secure your seatbelt. Keep the engine running so airbags remain operational. Recline your seat below window level and cover your head with a blanket, coat, or your arms to protect against flying debris. Never shelter under highway overpasses, as these create dangerous wind tunnels that intensify flying debris.
Keeping Your Vehicle Tornado-Ready With Regular Maintenance
Regular vehicle maintenance isn’t just about extending your car’s lifespan—it’s a pivotal safety measure when severe weather strikes. When a tornado warning sounds in San Antonio, you’ll need a vehicle that responds reliably.
Maintain your tires with proper inflation and adequate tread to navigate debris-strewn roads. Check your brakes regularly—they’re your first line of defense when needing to stop suddenly.
Keep your gas tank at least half full during tornado season to avoid being stranded during evacuations. Don’t forget your windshield wipers and fluid; visibility becomes critical during severe storms.
Test your headlights and emergency flashers periodically. A well-maintained battery guarantees your vehicle starts when you need to leave quickly.
