Extreme Heat Car Safety Tips: ADAC Warns of Tire Risks and Other Hidden Dangers

High temperatures pose significant risks to drivers, with the ADAC emphasizing the critical importance of proper tire pressure to prevent dangerous blowouts. According to the German Automobile Club, extreme heat can increase the likelihood of tire failures due to excessive heat buildup, urging drivers to check pressure before long trips.

Why Tire Pressure Matters in Extreme Heat

The ADAC warns that underinflated tires are particularly vulnerable during heatwaves. When temperatures rise, the air inside tires expands, increasing internal pressure. However, if the tire is already underinflated, the structural integrity may weaken, leading to a sudden blowout. “A low tire pressure is a serious risk in high temperatures and must be avoided,” the ADAC states.

Experts recommend checking tire pressure regularly, especially before long journeys. The manufacturer’s recommended pressure, typically found on a sticker inside the driver’s door, should be followed to ensure safety. A 2022 study by the European Transport Safety Council found that 28% of tire-related accidents occurred due to improper inflation, highlighting the importance of this precaution.

How to Safely Park and Cool Your Vehicle

Parking in direct sunlight can raise a car’s interior temperature to 60°C (140°F) within minutes, according to the National Highway Traffic Safety Administration (NHTSA). To mitigate this, the ADAC advises parking in shaded areas or using reflective sunshades. If no shade is available, opening all windows briefly before turning on the air conditioning can help reduce the initial heat buildup.

Drivers should also avoid directing cold air from the AC directly at their body to prevent muscle stiffness or respiratory issues. The American College of Sports Medicine notes that sudden temperature changes can strain the body, particularly in vulnerable individuals.

Why Leaving Children or Pets in Cars Is Life-Threatening

Even a few minutes in a parked car can be fatal for children or animals. The National Safety Council reports that 39% of child heatstroke deaths in the U.S. occur when a caregiver accidentally leaves a child in the car. Temperatures inside a vehicle can rise 20°F (11°C) in 10 minutes, reaching 120°F (49°C) within an hour.

The ADAC emphasizes that no situation justifies leaving a child or pet unattended in a car. If someone notices a person or animal in distress, they should immediately contact emergency services. In some states, laws allow bystanders to break a window to rescue someone in danger, provided they document the incident with photos or videos.

How Dehydration Affects Driving Ability

Even mild dehydration can impair reaction times and concentration. A 2021 study published in the journal Frontiers in Psychology found that a 1% fluid loss reduced cognitive performance by 15%. Drivers should carry water and sip regularly, especially during long trips. The World Health Organization recommends consuming 3–4 liters of water daily in hot weather, with additional intake if exercising or sweating heavily.

Which Common Items in Your Car Pose Fire Hazards?

High temperatures can cause aerosol cans, electronics, and certain medications to become unstable. The European Automobile Association (ACE) warns that spray cans may explode at 50°C (122°F), while smartphones and power banks can overheat and catch fire. A 2020 incident in Germany saw a car catch fire after a lithium-ion battery overheated in direct sunlight.

To reduce risks, drivers should avoid leaving flammable or heat-sensitive items in their vehicles. Plastic water bottles should also be removed, as they can act as magnifying glasses and ignite dry vegetation.

Why Flip-Flops Are a Safety Hazard While Driving

Open footwear like flip-flops can slip off the pedals or get caught under the accelerator, increasing the risk of accidents. The German Federal Highway Research Institute (BASt) notes that 12% of drivers involved in minor collisions wore unsuitable footwear. While no legal ban exists, drivers who cause accidents due to improper shoes may face liability claims.

Experts recommend wearing closed-toe shoes with good traction. A 2023 survey by the German Insurance Association found that 67% of drivers admitted to driving in sandals at least once a month, underscoring the need for awareness.

What to Do If You Encounter a Distressed Person or Animal in a Car

If you see someone or an animal in a hot vehicle, immediately call emergency services. The ADAC provides a 24/7 hotline for such situations. In urgent cases, breaking
