The second half of August and the month of September are usually times prone to the formation of storms. The thermal contrast between two or more air masses of different temperatures creates a perfect scenario for the appearance of these atmospheric manifestations that are usually accompanied by electrical equipment.

Driving under these conditions requires extreme caution to avoid increasing the chances of suffering an accident. Wet asphalt and reduced visibility associated with these episodes are two risk factors while driving. On the one hand, the loss of tire grip can lead to aquaplaning and on the other, the lack of clarity in the perception of the environment can make it difficult to anticipate obstacles and changes on the road.

But beyond the risk posed by driving on a wet surface and without optimal visibility conditions, there is another element that, without a doubt, tends to worry drivers: lightning. These electrical flashes add extra anxiety to vehicle occupants due to the fact that they can directly impact open areas, including roads.

When we find ourselves in the middle of a thunderstorm while driving, it is essential to make safe decisions so as not to put road safety at risk. The main recommendation is to find a safe place to stop – a service road can be a good place – and wait for the storm to stop. To reach the service road under these weather conditions we must drive calmly and brake gently instead of suddenly pressing the pedal.

In the middle of a storm with lightning and thunder, a question usually flies over our minds when we are driving. Is the car a safe haven from lightning? The answer is yes. The explanation is based on the principle of the Faraday Cage, whose name comes from the British scientist Michael Faraday.

This principle maintains that the electrical charge is distributed uniformly throughout the metal surface, such as that of a vehicle, without reaching the interior of the vehicle. The lightning discharge is dispersed along the outer surface of the car and is conducted to the ground, ensuring the complete safety of people inside the passenger compartment.

The only thing to keep in mind is to avoid contact with the metal parts inside the car and keep the windows closed. Following these guidelines, we can categorically state that the car provides a safe shelter during a thunderstorm.

However, it is important to be alert to the roar of thunder that accompanies lightning, since its sound intensity can exceed 110 decibels. Noises in the 100 to 110 dB range are at the toxic threshold, which could cause damage to the middle ear.

For this reason, it is advisable to disconnect all electronic elements that are not essential, starting with the car radio and mobile phone. We should only keep the engine, lights and windshield wipers on to minimize the risk of breakdowns. Contrary to what one might imagine, electric cars are better protected than traditional cars in the event of a lightning strike by having high-voltage electrical equipment.

To know precisely where electrical discharges are occurring, we can consult the website of the State Meteorological Agency (AEMET). In addition, various mobile applications such as Alarma Rayos, Lightning Alarm Weatherplaza, Blitzortung or Storm Radar provide real-time information on atmospheric electrical activity. These tools allow you to make preventive decisions and plan trips safely during adverse weather situations.
