What is the purpose of adding water to a large truck?

[VonDominic]

The function of the water tank in a large truck is to compensate for thermal expansion and contraction. It collects the overflow of cooling water at high temperatures and allows the cooling water in the container to flow back into the radiator at low temperatures. Here are some tips for driving when encountering large trucks: 1. Avoid truck blind spots: Trucks have large blind spots. During daily driving, the right-side blind spot of a truck is particularly hazardous. Often, trucks drive along the center line of the road, and sometimes slow vehicles block the fast lane, forcing drivers to overtake from the right side of the truck. This situation is highly prone to traffic accidents. 2. Dangers of truck turns: When a large truck turns, there is a specific term called 'inner wheel difference,' which refers to the difference between the front and rear wheels on the turning side. If a car driver stays in this area, the truck driver cannot see anything there from inside the truck. It is essential to move away quickly.
