Heat in the car: when will it be dangerous?

Just waiting 15 minutes in the car without leaving the air conditioning on can cause the inside temperature in a car to rise from 24 ° to 30 ° outside. After half an hour it will be 40 ° and after an hour it will be 50 ° in the car. At these temperatures, there is extreme danger for people sitting in the car in the blazing sun. The heat builds up and the inside temperature of the car rises rapidly.

Why do children cope with heat worse than adults?

While adults sweat a lot to cool off at high outside temperatures, this regulation system in children is not yet as pronounced until puberty. From the age of five, children can sweat so much that optimal heat regulation can take place.

What to do if children or dogs are trapped in the overheated car?

If a passerby notices a dog in hot weather in the vehicle, the dog should immediately try to find the dog owner or the driver. This means that if the car is in front of a supermarket, it should be called for the owner of the vehicle as soon as possible in the supermarket. If this option is not possible, the police or fire department should be notified so that the vehicle door can be opened. If neither the owner of the car nor the police can be there in time to rescue the animal from need, an attempt can be made to rescue the animal itself. However, this is only recommended if the animal is recognizable in acute danger to life, because breaking a window pane can be considered material damage.

If the vehicle in question is an electric car that can be fully air-conditioned without a combustion engine so that a slight whirring can be heard, you can assume that the inside temperature in the car is low and pleasant.

When children are sitting in the car, it should be determined whether they are just sleeping or are already passed out. By knocking on the car window, you can try to elicit responses from the kids to make sure they’re okay. If the child is in danger and you cannot notify the owner of the car or the police in good time, you can break a car window. However, be careful not to inflict additional injury to the child from broken glass.

Do tinted windows help against heat in the car?

In the past, the windows of a car served tinted windows in the car provide protection against sunlight and UV protection, which means that the heat in the car does not rise as quickly and strongly as without tinted car windows. In addition to the sun protection that the car windows offer with a sun protection film or tinted windows, they have the advantage that they provide privacy for the center of the car. However, tinting all car windows is not allowed. Which car windows can be tinted and which not? What is the difference between a heat film and a tinted car window? What do tinted windows cost and how are they attached?

Tinted windows or window film: which is better?

When tinting a car window, the window can be metallized. There are different metals that are used for vapor deposition: these include titanium, chrome, silver and silicon. The tint ensures a longer durability of car windows and UV protection for the drivers.
Another method of tinting the car window is to have it steamed with a mixture of water and plastic – a colored polyurethane dispersion.

To obtain sun protection for the car window, a heat protection film can also be stuck on. The adhesive film also offers UV protection, but is difficult to apply. In order to wrap car windows correctly and properly, not only the necessary tools are required, but also patience and fine motor skills. The application of the sun protection film is complicated for inexperienced people. If an inexperienced hand is at work, the film can cause many bubbles on the pane. This can be seen both from the inside and the outside and looks ugly. Therefore, it is advisable to have a professionally trained specialist stick the sun protection film on the car, because they have the experience and expertise to film the car windows perfectly.

Depending on the degree of tint and quality, the cost of a tint film is between $15 and $150. However, this price does not include the installation of the adhesive film. The cost of foiling the car windows is between $200 and $500. This guideline value is an estimate that varies greatly from car model to car model.

How do you apply window film correctly?

In order to guarantee heat protection in the car during the summer, it makes sense to apply the sun protection film before the first hot days. Before the sun protection film is stuck to the car window, the window must be cleaned thoroughly from the inside and outside. After the tint film has been cut to fit the window, the film can be sprayed with the assembly mixture to attach it to the window. The film should be placed in the middle of the pane so that working from the inside out is made easier. To get rid of smaller wrinkles, you can work with the hair dryer. The film now needs about three weeks for the drying process. Since the necessary working conditions and expertise are not given to everyone,

How to use the air conditioning in the car correctly?

The air conditioning is a great blessing in hot temperatures because it offers cooling in the car. But this blessing can quickly become a curse if the air conditioning in the car is not used properly. So it should be noted that the air conditioning system does not differ significantly from the outside temperature in the car. The ideal difference is 6°C (43°F), which should prevent a circulatory collapse when you get out of the car. It is unfavorable for the health to direct the fan of the cool air directly at you. This is to prevent severe colds and tension. Find out how the car can be cooled in the event of a defective air conditioning system here .

Driving a car in summer: how do I behave correctly?

When driving a car in summer it is important to think and plan ahead. For example, when driving a car, the midday sun – between 12 noon and 3 p.m. – should be avoided. If the car has been standing in the sun for too long, all windows and doors should be opened first to let the heat escape. If necessary, a blanket can be placed on the seat so as not to burn yourself when you sit down. To cool the steering wheel, wait until it cools down.

If the car is to be parked, a shady parking space should be found. However, this is not always possible, which is why tinting films and tinted windows on the car can counteract the heat.

Cool Info:
A car’s windshield has grown by more than 60 percent since 1980. Since then, the number of window areas has increased by an average of 24 percent.

The driver should drink plenty of water on a regular basis during long car journeys. The heat in the car can be overwhelming – especially with closed shoes, driving barefoot is a great temptation. The road traffic regulations do not stipulate which footwear must be worn when driving. Flip-flops can provide the necessary cooling, but can possibly get tangled with jerky movements. Driving completely barefoot doesn’t always seem easy, because the feeling of pressure and stability is unusual due to the lack of a shoe profile. If the barefoot driver gets involved in an accident, the driver can be partially blamed for the lack of care.

Can the tires and engine be damaged in summer heat?

The tires and engines could take some damage in the summer heat. The tires age faster due to the UV rays and become porous. But at high outside temperatures, there is no danger to the tires and none emanates from them. A safe journey can be guaranteed despite the increasing air pressure in the tires. The engine can be damaged in the summer heat if the fuel in the tank expands, escapes into the ventilation and ignites. Therefore, it is advisable to fill up the tank completely at high outside temperatures.


Driving in summer can make the summer heat in the car unbearable if the outside temperature causes the inside temperature in the car to rise rapidly. To cool the driver and fellow passengers in the car, windows can be tinted at night or covered with a sun protection film. Darkened car windows offer sun protection and UV protection. In summer heat, children and dogs should never be left in the car – even if the windows are slightly open.
