What Needs to Be Checked Before Taking a Car on the Highway?

Before driving on the highway, it is necessary to check the vehicle's condition, including the fuel gauge, tire pressure, lights, brakes, and other aspects, as well as prepare necessary supplies. Below are some specific items to inspect before highway driving: Check Fuel Level: Highway driving consumes more fuel than expected. For example, a car with a fuel consumption of 10 liters per 100 kilometers will use about 10 liters to travel 100 kilometers at 50 km/h. However, driving at 100 km/h on the highway for the same distance will consume approximately 16 liters. Since fuel consumption increases significantly at high speeds, ensure sufficient fuel is prepared. Check Tire Pressure: While driving, tires undergo compression and expansion, known as tire deformation. This phenomenon is more pronounced when tire pressure is low and speed is high, leading to excessive internal heat. This can cause the rubber layer to separate from the cover layer or result in the outer tread rubber breaking apart, potentially leading to a tire blowout and accidents. Therefore, before highway driving, tire pressure should be slightly higher than usual. Others: Inspect engine oil, coolant, fan belts, steering, transmission, lights, signals, and other components.
Before taking my kids on the highway, I make it a habit to thoroughly inspect the car because the safety of the whole family depends on it. The most critical aspect is the tires—their pressure and tread must be appropriate, as a blowout at high speed is no joke. I use a tire pressure gauge to check, and if the wear is severe, I replace them. The braking system can't be overlooked either; I take a short drive to test responsiveness and listen for any unusual noises. Are all the lights working? I test the headlights, brake lights, and turn signals, especially for night driving, as visibility relies entirely on them. I check the coolant and oil levels on the dashboard to prevent engine overheating and breakdowns. I ensure the child safety seats and adult seat belts are securely fastened, and I secure any loose items in the car to prevent them from flying around. High-speed winds make clean windows essential for clear visibility. The entire inspection takes just a few minutes but helps prevent accidents and gives peace of mind while driving.
