The scorching summer heat that has hit in the middle of spring is not only uncomfortable but also poses a significant risk for drivers. It may seem like a trivial matter, but in reality, it can lead to dangerous situations behind the wheel. Studies suggest that driving in high temperatures can be as hazardous as driving under the influence of alcohol.
Meteorologists are alarmed by the unusual and unseasonable high temperatures being recorded in April, which is typically a mild month. As a driver, one needs to exercise extreme caution during such weather conditions. Despite being an often-overlooked matter, high temperatures can result in serious driving problems.

The extreme heat problem
The usual advice and warnings regarding driving in extreme heat would typically be directed towards the summer months, but the current situation demands practicality. With temperatures soaring to levels that could peak at nearly 40 degrees Celsius during the hottest hours of the day, and minimums hovering around 20 degrees, it’s important to take precautions. In short, it’s going to be scorching hot, and unless you cool down with air conditioning, your car is likely to become uncomfortably hot.

The rising temperature outside can lead to the inside of the car being heated up to around 30 degrees Celsius, especially when the outside temperature reaches 38 degrees. This poses a significant risk, as the General Directorate of Traffic (DGT) recommends maintaining a maximum temperature of 24 degrees Celsius inside the vehicle. Once the temperature exceeds this level, risks and problems can arise.
The risks behind the wheel
Taking driving seriously and prioritizing safety is always crucial, as emphasized by experts at the Directorate General of Traffic. Driving while fatigued, unfocused, or under the influence of certain substances is strongly discouraged. Heat is also a risk factor that can potentially lead to trouble while driving.
When temperatures inside the vehicle reach 30 degrees or above, fatigue can set in more quickly, leading to drowsiness and reduced reaction time. Other issues such as leg pain, excessive sweating, and impaired visibility may also arise. Slower reaction times due to extreme heat can be more than twice as long as in comfortable temperatures, which can be critical in preventing accidents. Thus, it is important to take necessary precautions to avoid driving in extreme heat and protect oneself from its potential dangers.

The CEA Foundation has provided valuable information about the risks of driving in hot temperatures. According to their studies, driving with 30 degrees inside the car can reduce your attention to the road by 10%. If the temperature rises even higher to 35 degrees, the effects are equivalent to those of driving under the influence of alcohol. This dangerous situation can lead to slower reaction times and mistakes behind the wheel, which significantly increases the risk of accidents. Therefore, it is important to take heat seriously and take the necessary precautions to stay safe while driving in hot weather.
Security recommendations
The Foundation of the European Automobile Commissioner offers useful advice for driving in high temperatures. They suggest rolling down the windows before starting the car to reduce the initial temperature inside, avoiding driving during the hottest parts of the day, and driving in the early morning or evening instead. It is also important to use the air conditioning and set it to 24 degrees Celsius. To prevent fatigue, it is recommended to take a break every 200 kilometers traveled. During breaks, it is advisable to eat light and nutritious foods rich in vitamins and protein. By following these tips, you can reduce the risk of accidents and ensure a safe and successful journey.

It is important to highlight that drinking alcohol should be avoided at all costs while driving in extreme heat. It is important to remember that the negative effects of heat on the body can be similar to those of alcohol, and drinking can amplify these effects, increasing the risk of accidents on the road. It is also recommended to wear appropriate clothing that is comfortable, loose-fitting, and enables safe driving.
