What Should Be Checked in a Vehicle Before Driving on the Highway?

Before driving on the highway, the vehicle should be checked for tires, various fluid levels, the steering system, etc. Tire Inspection: Visually inspect for signs of cracks or bulges; check tire pressure. In summer, it's advisable to slightly reduce the pressure by 0.1-0.2 bar to prevent blowouts. Fluid Inspection: Check if the engine oil is sufficient, as high-speed engines require good lubrication. Prolonged high-speed driving can lead to increased water temperature, and insufficient coolant may cause the engine to overheat, leading to smoke or even fire in the engine compartment. Brake fluid should not be deteriorated, as this can cause it to boil easily, resulting in insufficient braking force. Steering System Inspection: Check for any looseness in the steering wheel by attempting to turn it. According to regulations, when driving straight for one kilometer, the vehicle's lateral deviation should not exceed 5 meters. Also, inspect the rotating components on the chassis for any deformation or sticking.

Before hitting the highway, safety is my top priority. I thoroughly inspect the tires, checking the air pressure to ensure it's within the manufacturer's recommended range. If the tread is severely worn, I replace it immediately to avoid the serious consequences of a blowout at high speeds. I also test the brakes by gently pressing them a few times to listen for smooth operation and ensure the stopping distance feels short. The lighting system can't be overlooked—I check the headlights, brake lights, and turn signals to make sure they all work, as they're crucial for nighttime driving. For fluids, I glance at the oil dipstick to confirm it's clean and ensure the coolant is topped up, as the engine heats up significantly on the highway. I check the spare tire's pressure and make sure the tool kit is complete, so I can change a tire myself in an emergency. Lastly, I listen for any unusual noises, fill up the tank to avoid scrambling for gas mid-trip, and take care of these small details to prevent major headaches.

With years of driving experience, I always prioritize performance checks before hitting the highway. Engine oil level is a must-check; dark color or low quantity can damage the engine. Coolant should be sufficient, crucial for long-distance heat dissipation. Transmission fluid should feel smooth for effortless gear shifts. Inspect belts for cracks, ensuring the fan belt has moderate tension. Adjust tire pressure accurately, check tread depth against wear indicators—uneven pressure affects handling. Test the suspension system; no strange noises over bumps, or high-speed turns may become unstable. Ensure no warning lights on the dashboard, with stable water temperature and oil pressure. Brakes should have clear feedback; inspect pad and disc thickness. These details ensure the car runs steady and fast.

As a family user who frequently travels long distances, I prioritize comfort and convenience. The air conditioning's cooling effect is paramount to avoid stuffiness on hot days. Testing the battery ensures sufficient charge and smooth starts. Quickly checking tire pressure against the recommended values in the manual is essential. The lighting system must be fully functional, including headlights and turn signals. Don't forget to check the spare tire's pressure—don't wait until you need it. Keep emergency supplies in the car: water, snacks, and a first aid kit, just in case the kids get hungry or have minor injuries. A quick check of oil and coolant levels, along with ensuring no warning lights are on the dashboard, makes the journey easier and safer.
