The safe following distance when driving varies according to speed: 1. When driving at a crawling speed (below 20 km/h), the safe distance should be no less than 10 meters; 2. When driving at low speed (below 40 km/h), the safe distance should be no less than 30 meters; 3. When driving at medium speed (around 50 km/h), the safe distance should be no less than 50 meters; 4. When driving at high speed (above 60 km/h), the safe distance should be 60 meters; 5. When driving on highways (above 100 km/h), the safe distance should be no less than 100 meters.

I think maintaining a safe following distance is super important when driving. With over a decade of driving experience, I've found the simplest method is to follow the 'three-second rule'—pick a fixed point on the roadside, and only pass it three seconds after the car ahead does. The faster the speed, the greater the distance should be—for example, at 60 km/h, leave at least 100 meters. Never underestimate this. Last time, my friend didn't keep enough distance in the rain, couldn't brake in time, and rear-ended another car. His car was damaged, and he had to pay for repairs—what a loss! In bad weather like fog or slippery roads, I usually double the distance to ensure enough reaction time. Remember, a safe following distance can save your life. Always observe road conditions carefully, don't tailgate, and prioritize safety—it's never wrong.

What Causes the Engine Fan to Start Frequently?

Engine fan frequently starting reasons are as follows: 1. The coolant temperature has indeed reached the point where cooling is needed: The causes of rapid high temperature in the coolant are either low water level or some issues in the water circuit circulation. Check whether the temperatures of the upper and lower hoses are the same. 2. The coolant temperature switch is faulty: It starts cooling prematurely before reaching the required temperature. If the coolant temperature remains low, the engine's complete combustion rate will decrease, meaning incomplete combustion and higher fuel consumption. Below are the relevant details about the engine radiator: 1. Introduction: Also known as the engine radiator, it is a key component of the water-cooled engine cooling system. It ensures the engine operates within the normal temperature range by forcing water circulation for cooling, acting as a heat exchange device. 2. Principle: The radiator works by dissipating the heat energy of the coolant. To maintain the proper temperature of the internal combustion engine, a water pump driven by the engine forces the coolant to circulate through various parts of the engine. The device that absorbs the heat generated by the engine and dissipates it into the air is the radiator.
