What Inspections Should Be Done Before Driving on the Highway?

[NovaRose]

Before driving on the highway, it is necessary to inspect the vehicle's condition, including the fuel gauge, tire pressure, lights, brakes, and other aspects, as well as checking the spare parts. Here are some specific items to inspect before highway driving: 1. Check the fuel level: When driving on the highway, fuel consumption is higher than expected. For example, a car with a fuel consumption of 10 liters per 100 kilometers will consume about 10 liters when driving at 50 km/h for 100 kilometers. However, when driving at 100 km/h on the highway for the same distance, it will consume approximately 16 liters. Highway driving significantly increases fuel consumption, so ensure you have sufficient fuel. 2. Check the 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. Under such conditions, the internal temperature of the tire rises abnormally, leading to separation of the rubber layers or fragmentation of the outer tread, which can cause a blowout and result in an accident. Therefore, before highway driving, the tire pressure should be slightly higher than usual. 3. Others: Inspect other components such as engine oil, coolant, fan belts, steering, transmission, lights, and signals.
