A thunderstorm is one of the most beautiful and at the same time destructive natural phenomena. Powerful lightning strikes, thunderclaps and gusty winds create an impressive spectacle, but are fraught with mortal danger. Especially if you are in an open space - e.g. run to the car in the parking lot or trying to wait out the bad weather by the side of the road.
Many drivers underestimate the risks associated with running during a thunderstorm. A few seconds in the rain may seem like it won't do any harm, but statistics say otherwise: Every year dozens of people die from lightning strikes, and cars become targets for discharges. Why shouldn’t you run in a thunderstorm, especially if you’re driving or next to a car? Let's understand the physics of this phenomenon and the real threats.
In this article you will learn not only how lightning interacts with the human body and metal structures, but also what hidden dangers Even short dashes are fraught with danger. We will analyze real cases from the practice of rescuers, analyze myths about car safety and provide a checklist of actions if a thunderstorm catches you on the road.
Spoiler: even if you run to the car, this does not guarantee your safety. Lightning can puncture tires, set fire to the fuel tank, or destroy vehicle electronics. - and this is only part of the risks.
1. Lightning and the human body: why running increases the chances of being struck
Humans are 70% water, which makes them an excellent conductor of electricity. When lightning strikes the body, the current follows the path of least resistance—usually along the nervous system and blood vessels. Running during a thunderstorm increases the risk of injury by 3-5 times, and here's why:
Firstly, movement creates antenna effect. The rising and falling of legs, the swinging of arms, and even breathing alter the electrical field around the body, attracting a discharge. Research US National Weather Service show that a person in motion in an open area becomes priority target for lightning, especially if it is higher than surrounding objects.
Secondly, running disrupts "low profile" rule. Lightning strikes more often at the highest points on the ground. When you run, your head rises higher than if you were crouching or lying down. Even a difference of 30-50 cm can become critical.
- 🔥 Lightning Temperature reaches 30 000°C - 5 times hotter than the surface of the Sun. When it enters the body, it causes instantaneous evaporation of fluids and explosive destruction of tissue.
- ⚡ Current strength in a lightning strike - up to
200,000 Amps. For comparison, the current lethal to humans is only0.1 A. - 💀 Consequences of the blow: cardiac arrest, paralysis, memory loss, 3rd degree burns throughout the body.
Most lightning victims survive but become disabled. According to World Meteorological Organization, 24% of victims lose the ability to walk, and 70% suffer from chronic pain and neurological disorders.
2. A car as a target: why a car won’t always save you
Many people think that the metal body of a car reliably protects against lightning according to the principle Faraday cages. This is only partly true. Yes, a closed car reduces the risk of injury to the person inside, but does not guarantee 100% security. Here's why:
Firstly, modern cars contain a lot of plastic and composites, which do not shield the electromagnetic field. For example, in Toyota Prius or Tesla Model 3 the body consists of 40% non-metallic materials. Lightning can pass through glass or plastic panels, causing an arc inside the vehicle.
Secondly, fuel system and electronics are vulnerable. A lightning strike to a car often leads to:
- 🔥 Fire of the fuel tank (if the discharge enters the exhaust system or gas pipeline).
- 💻 Out of order
ECU(electronic control unit), which makes the car uncontrollable. - 🎛️ Damage ADAS- systems (adaptive cruise control, 360° cameras), which increases the risk of accidents.
According to statistics National Research Center "Kurchatov Institute", every 10th lightning strike on a car causes it to catch fire. At the same time, insurance companies often refuse payments, citing “force majeure”.
⚠️ Attention: If you see lightning strike a car, do not touch it for 10-15 minutes. The body may be under voltage and the battery may be overheated. It is better to move 20-30 meters away and call rescuers by number 112.
What to do if lightning strikes your car?
1. Stop immediately, turn off the engine and turn on the hazard lights.
2. Do not touch metal parts of the interior (door handles, steering wheel).
3. Leave the car only if it is not on fire - otherwise, move 50+ meters away.
4. Check yourself and passengers for burns (they may be hidden under clothing).
5. Call rescuers and do not try to start the car before they arrive - a second discharge is possible.
3. Step Voltage: The Invisible Killer in the Parking Lot
Even if lightning did not strike you, but the ground or a pole nearby, you are still in danger. Step voltage - this is the potential difference between two points on the surface of the earth, which occurs when current spreads from the point of impact. The wider your steps, the higher the risk of defeat.
Example: if lightning strikes a tree in a parking lot and you run past it with a step of 1 meter, then the potential difference between your legs can reach several thousand volts. This is enough for the current to pass through the body and cause fibrillation of the heart.
The danger zone extends to radius up to 30 meters from the point of impact. In this case:
- 🚗 Asphalt and concrete don't protect - they conduct current, especially if wet.
- 👟 Rubber sole shoes won't save: for insulation you need a sole with a thickness of at least 3 cm (usually 0.5-1 cm for sneakers).
- 🌊 Puddles increase the affected area - water is an excellent conductor.
Rescuers recommend in such a situation goose step: The heel of one foot touches the toe of the other without leaving the ground. This minimizes the potential difference. But the best option is don't move at all, until 20-30 minutes have passed since the last lightning strike nearby.
| Material underfoot | Danger level | Max. safe distance from impact |
|---|---|---|
| Dry grass | Medium | 15 m |
| Wet asphalt | High | 30+ m |
| Gravel or crushed stone | Low | 10 m |
| Puddle 5+ cm deep | Critical | 50+ m |
4. Secondary effects of thunderstorms: what kills more often than lightning
Lightning is not the only danger during a thunderstorm. 80% of accidents occur due to secondary factors that many ignore. Here's what can happen if you decide to run toward a car or between buildings:
Gusts of wind (up to 120 km/h during a squall) they knock you down, throw objects (branches, garbage cans) and even overturn light cars. In 2022, in Moscow, a hurricane wind during a thunderstorm knocked down a tree onto parked cars - 3 people died, trying to run to cover.
hail the size of a chicken egg (5-10 cm in diameter) may pierce the windshield or cause traumatic brain injury. In 2021, hail damaged Sochi 1,200 cars in 20 minutes.
Panic and accident. According to the traffic police, during a thunderstorm the number of accidents increases by 40%: Drivers lose control due to blinding flashes, brake hard, or drive off the road in an attempt to hide.
- 🌪️ Tornado: in Russia up to 100 tornadoes are recorded per year. Even a weak whirlwind lifts objects weighing up to 50 kg into the air.
- 🌊 sudden downpour causes road flooding. In 2023 in Krasnodar due to a thunderstorm 7 cars drowned — drivers did not have time to assess the depth of the puddles.
- 🚨 Falling trees and poles: wet soil softens and the roots do not hold the trunk. In St. Petersburg, over the past 5 years, people have died due to thunderstorms. 12 peoplewhere trees have fallen.
If a thunderstorm finds you in your car on the highway, do not stop under bridges or overpasses. Firstly, water accumulates there (risk of water hammer). Secondly, metal structures attract lightning. It is better to pull over to the side of the road on a flat area and wait out the bad weather with your hazard lights on.
5. Security Myths: What Really Doesn't Work
There are a lot of “tips” floating around on the Internet and among drivers on how to protect yourself from thunderstorms. Most of them are not only useless, but also dangerous. Let's look at the most common myths:
Myth 1: “Rubber wheels and soles protect against lightning”
In fact: Rubber is a dielectric, but its layer in shoes or tires is too thin (1-3 mm) to withstand voltage in millions of volts. Lightning penetrates rubber like paper. For example, in 2020, in the Moscow region, lightning struck a man wearing rubber boots - the current passed through the body, leaving burns on the feet.
Myth 2: “If you hide under a tree, you will be safe”
Fact: Trees are one of the main targets for lightning. Oak, poplar and pine trees attract discharges due to high moisture content. According to Rosleskhoz, every 4th tree, which was struck by lightning, lights up. If you stand nearby, you risk getting burned or suffocating from smoke.
Myth 3: “You can use a telephone or radio in the car”
Fact: The electromagnetic pulse from lightning destroys electronics. In 2021, in Rostov-on-Don, a lightning strike on a car caused battery fire iPhone the passenger's phone exploded, leaving burns on his hand.
- ☂ "An umbrella will protect you from lightning" → The metal frame of the umbrella works as a lightning rod. In Japan, a case was recorded where lightning passed through an umbrella and killed a woman.
- 🚗 “If you close the windows, lightning will not pierce the car” → Glass will not save: in 2019 in Germany, lightning pierced the windshield BMW X5, injuring the driver.
- 🏃 "If you run very fast, you can reach it in time" → The average running speed of a person is
15 km/h, and lightning moves at speed1,000,000 km/h. There is no chance to overtake the discharge.
The only reliable way to protect yourself is don't go out into the open 30 minutes before a thunderstorm and 30 minutes after it. Lightning can strike up to 15 km from the epicenter of a thunderstorm front!
6. What to do if a thunderstorm catches you on the road: instructions for drivers
If you find yourself on the road or in a parking lot during a thunderstorm, follow this algorithm. Every second matters - Wrong actions can cost lives.
1. Assess the situation:
- 📍 If you are on the highway, pull over to the side of the road away from poles and trees (minimum 50 m).
- 🚗 If in a parking lot, stay in the car, but do not touch metal parts.
- 🚶 If you are outside the car, look for shelter in a building (not in a pavilion or canopy!).
2. Rules of behavior in the car:
Turn off the engine and remove the key from the ignition|Turn off all electrical appliances (air conditioning, radio, navigator)|Close the windows and sunroof (if equipped)|Do not touch the steering wheel, door handles or gearshift|If lightning strikes nearby, do not go out for 10-15 minutes-->
3. If you are outside the car:
- 🏃 Don't run! It is better to squat down, clasping your knees with your hands (this reduces the height and area of contact with the ground).
- 📵 Turn off your phone - it can attract lightning like a metal object.
- 🌳 Stay away from single trees, metal fences and power lines.
⚠️ Attention: If you feel your hair stand on end or hear a crackling sound in the air, these are signs that lightning is about to strike. Immediately take the “curl” position: squat down, hug your knees, tilt your head to your chest and cover your ears with your palms.
7. First aid for lightning strikes: what to do before doctors arrive
If someone near you has been struck by lightning, the first 5 minutes decide everything. Errors in providing assistance can lead to death even with a seemingly minor injury.
Step 1: Check for signs of life:
- 🫀 Pulse: Check on the carotid artery (not the wrist!). Lightning often causes cardiac fibrillation.
- 🌬️ Breathing: if it doesn't exist, start
CPR(cardiopulmonary resuscitation). - 🔥 Burns: Can be hidden under clothing. Especially check places of contact with metal (belts, watches, keys).
Step 2. Actions in case of cardiac arrest:
- Place the victim on a hard surface.
- Do 30 chest compressions (depth 5-6 cm, rate 100-120 per minute).
- Do 2 mouth-to-mouth breaths (if you are not afraid of infection).
- Repeat the cycle until the ambulance arrives or breathing is restored.
Step 3. What NOT to do:
- ❌ Watering - this aggravates the burns.
- ❌ Give alcohol — he intensifies the shock.
- ❌ Move the victim, if there is no direct threat (for example, fire). Improper transportation may cause paralysis.
According to EMERCOM of Russia, 70% of lightning victims surviveif they received first aid on time. Without it, the mortality rate exceeds 90%.
A car's first aid kit should contain sterile bandages, antiseptic (for example, Miramistin), gloves and CPR instructions. Lightning often causes bleeding from the ears and nose - they need to be swabbed immediately.
FAQ: Frequently asked questions about safety during thunderstorms
⚡ Can lightning strike a moving car?
Yes, and this happens more often than it seems. In 2022, lightning struck the United States Tesla Model S at a speed of 110 km/h. The driver escaped with fright, but the car's electronics failed. The risk is higher if the car is driven in an open area (field, bridge) or if there are metal elements installed on the roof (trunk, antenna).
What to do: If a thunderstorm starts while driving, pull over to the side of the road and wait it out in the car with the engine off.
🚗 Does a car protect against lightning better than a building?
No. Buildings with lightning rods and grounding are more reliable. The vehicle is only protected if:
- The body is completely metal (not carbon or plastic).
- The windows and sunroof are closed.
- You do not touch any metal parts of the interior.
B Volvo and Mercedes with an all-metal body the risk is lower, but it is still there.
🏃 How long do you have to wait after a thunderstorm to get out of your car safely?
Minimum 30 minutes after the last clap of thunder. Lightning can strike up to 15 km from a thunderstorm front (“lightning from nowhere”). In 2021, in the Moscow region, a man got out of his car 10 minutes after it rained and was struck by lightning that came from a nearby cloud.
Check the weather on the radar (for example, in the application Windy or Meteum) - it shows the real movement of thunderstorm fronts.
📱 Is it possible to use a phone in a car during a thunderstorm?
It's better not to take risks. Although the phone itself does not attract lightning, it can:
- Create a false sense of security (you are distracted from monitoring the situation).
- Be damaged by an electromagnetic pulse.
- If it's wired CarPlay/Android Auto, current can flow through the cable.
Exception: emergency call to 112. In this case, use the speakerphone without touching the phone with your hands.
🌩️ Is it true that lightning never strikes twice in the same place?
This is a dangerous myth! Lightning often strikes one place several times in a row, especially if it is a tall object (skyscraper, mast, tree). Lightning in New York in 2020 6 times in a row hit the spire Empire State Building in 30 minutes.
For cars, this means that if lightning has already struck a pole or tree nearby, do not come closer than 50 meters to this place — repeated discharge is possible.
