Traffic jam questions – riddles of traffic history solved
Why does the truck have a cat flap?
Nowadays, parents can confidently answer questions from the back seat about the meaning of the BD-13 license plate “of that car” via smartphone. That leaves the scary questions in traffic jams: The kids want information about something technical.
Today’s final opponent: “Dad, why does the truck have a cat flap?” Moments of silence follow in the front row, anxiously glancing from seat to seat without turning their heads. No suspicion of perplexity should germinate in the rear.
- 1. stammered: “Uh, the driver can check if everything is all right.
- “2. sovereign: “So the driver can check the temperature. He drives food to the supermarket.”
- 3. worldly: “You know, he drives across the border and is not allowed to open the big door, customs can then look in through the flap.”
- 4. fanciful: “It’s a very big garbage truck and the flap lets all the bad air out.
- 5. absurd: “Through the flap he can unload the small packages better, otherwise they always fall out. Like your Lego box”

Correctly identified: All wrong. And those who answer the offspring’s questions in the style of number 6 should not be upset about the consequences later. By the way, answer number 4 is somewhat on the trail of the truth about this flap.
Fridge with bad air
If a truck, trailer or other body has such a flap in the large portal, then it is usually refrigerated or cooling vehicles. Since their doors close very tightly, if the temperature rises after unloading or if the vehicle is empty without refrigeration, the air would quickly become stale and germs would form as a result of condensation. Just like when the refrigerator is turned off and the door is closed. The flap is used to ventilate the cargo area when it is not in use or the cooling system is not in operation.
