Yes — it is generally safe to sit inside a car during lightning, as long as certain precautions are followed.
Is it Safe to Sit Inside a Car During Lightning?
Yes, sitting inside a car during a lightning storm is considered safe.
A car acts as a Faraday cage, meaning the lightning travels around the outside metal body and is directed safely into the ground.
Because of this, the occupants inside remain protected.
1. Why a Car is Safe During Lightning
A) Metal Body Acts as a Faraday Cage
- When lightning strikes a car, the electric current flows through the metal exterior.
- It does not travel through the inside of the car.
- The electricity passes to the ground, keeping passengers safe.
B) Current Avoids the Interior
The charge travels along:
- The car’s roof
- Metal frame
- Body panels
- Tires → eventually into the ground
Even though tires are not insulators strong enough to stop lightning, the electricity naturally follows the metal structure to the ground.
2. Which Cars Offer Better Protection?
Most Protective:
✔ Cars with a fully enclosed metal body
✔ Steel or aluminum body cars
✔ Pickup trucks with enclosed cabins
Less Protective:
❌ Convertibles
❌ Cars with soft tops
❌ Cars with fiberglass or plastic bodies
❌ Motorcycles, bicycles, open carts
These offer little or no Faraday cage protection.
3. What Parts of the Car Are Unsafe to Touch?
During lightning, avoid touching:
- Metal door handles
- Gear lever (if metallic)
- Radio or electrical components
- Steering wheel (if metal exposed)
- Window frames
- Any connected wires
These may conduct electricity if the car is struck.
4. What Should You Do If You Are in a Car During a Lightning Storm?
✔ DO:
- Stay inside the vehicle
- Keep your hands in your lap
- Close all windows
- Park safely away from tall isolated trees, poles, or water bodies
- Wait for the storm to pass
❌ DON’T:
- Touch metal surfaces
- Stand outside
- Lean out of the window
- Touch electronic devices connected to the car
- Exit the car until it’s safe
5. What Happens If Lightning Strikes a Car?
If a car is struck:
- You will hear a loud bang
- The car may shake
- Electronics may get damaged
- Tires may blow out (rare but possible)
- The passengers remain safe inside
The car may need inspection after the strike, but occupants usually remain unharmed.
6. Can Lightning Damage the Car?
Yes, it can cause:
- Electrical system failure
- Burn marks on roof or metal parts
- Damage to ECU or infotainment system
- Tire damage (rare)
But the physical safety of the passengers is usually unchanged.
7. Are Electric Cars Safe During Lightning?
Yes, electric cars (EVs) are also safe.
Their bodies are made of metal and provide the same Faraday cage effect.
Battery packs are heavily insulated and do not explode due to lightning.
8. What Should You Do After Lightning Strikes Your Car?
Once the storm ends:
- Inspect the car for electrical issues
- Check tires for damage
- Have the car checked by a technician if anything seems abnormal
But you do not need to exit during the storm.
9. Summary:
- Yes, it is safe to sit inside a car during lightning.
- The metal body protects you by directing lightning current around the outside.
- Avoid touching metal or electronics inside.
- Do not stay inside open-top or plastic-bodied vehicles.
- Cars may get damaged, but people inside remain safe.
