Can I wash the car directly after running 100 kilometers?

You can wash the car directly after running 100 kilometers on the highway. Here is an introduction to the speed limits for two-lane and three-lane highways: 1. Two-lane highway: A two-lane highway means there are two lanes in the same direction. The speed range for the right lane is 60 to 100 kilometers per hour, and the speed range for the left lane is 100 to 120 kilometers per hour. 2. Three-lane highway: A three-lane highway means there are three lanes in the same direction. The speed range for the far-right lane is 60 to 90 kilometers per hour, the middle lane is 90 to 110 kilometers per hour, and the far-left lane is 110 to 120 kilometers per hour. The left lane is the overtaking lane, hence it has a higher speed limit.
As a long-distance driver, I would advise you never to wash your car immediately after driving 100 kilometers. When the car has just stopped, the engine, brake discs, and other components are still hot, possibly exceeding 100 degrees Celsius. Spraying cold water on them can cause thermal contraction and expansion, leading to deformation or even cracks in the parts. In severe cases, it may result in brake failure, compromising driving safety. I once witnessed a friend rushing to wash his car, only to end up with cracked brake discs, requiring a full system replacement—a real hassle. It’s best to wait 15 to 20 minutes for the car to cool down before washing. During this time, you can check the tires or clean dust off the seats for a thorough maintenance routine. Of course, if the weather is extremely hot, with even greater temperature differences, rushing is even riskier—using a fan to aid cooling is a better approach. When washing, start with lukewarm water and gradually transition to protect your car’s critical components—this is a must-know for daily driving. Regular maintenance helps avoid costly major repairs.
