What maintenance is needed before a car goes on a long trip?

[DelAva]

Before a car goes on a long trip, it is necessary to check the fluids; carefully remove dust and clean the car surface; inspect whether the windshield washer fluid, coolant, engine oil, transmission fluid, power steering fluid, and brake fluid are clean and sufficient; check the tire system, including whether the tire screws are loose or show abnormal wear; inspect the electrical system, mainly focusing on whether the wipers, wiper blades, and front windshield washer nozzles are damaged; check whether the interior and exterior lights, horn, and remote control are functioning properly, etc. Below are some precautions for driving on highways: Drive in the designated lane: Highways have clearly marked lanes, including dedicated lanes for large vehicles, small vehicles, etc. When overtaking, once you occupy a lane, return to your own lane promptly after completing the overtaking maneuver. Do not occupy other lanes for extended periods. Additionally, the emergency lane should not be occupied for non-emergency reasons. Maintain a safe speed and avoid speeding: The dangers of speeding are well-known, whether on local roads or highways, as it can lead to irreversible consequences. Maintain a safe following distance: Under normal conditions, on dry roads with good braking, the following distance (in meters) should not be less than the speed (in km/h). For example, at 80 km/h, the distance should be no less than 80 meters; at 100 km/h, no less than 100 meters. Always pay attention to roadside distance markers. In rainy, foggy, snowy, or wet road conditions, the following distance should be doubled. Observe traffic signs: Always pay attention to roadside and overhead signs and markings while driving, and stay appropriately to the right to avoid running over the right lane divider, providing sufficient lateral distance for overtaking vehicles. Do not arbitrarily occupy the emergency lane in case of accidents: Traffic accidents are inevitable on highways. If other vehicles cause a blockage in the travel lane, do not occupy the emergency lane, as it may hinder rescue vehicles from performing their duties. Avoid fatigue driving and take timely breaks: Fatigue driving is extremely dangerous on highways. When fatigued, the body's reaction time slows down, making it difficult to respond correctly to sudden situations.

As a veteran driver who frequently takes long trips, I believe pre-departure maintenance should be done thoroughly. Tire inspection is most crucial - inflate to the exact pressure specified in the manual, as both overinflation and underinflation are unsafe at high speeds; check tread wear and replace if too thin. Don't forget to inflate the spare tire and prepare a complete tool kit for emergency tire changes. For fluids, use fresh engine oil (dirty oil makes engines temperamental); top up coolant to prevent overheating; ensure sufficient brake and power steering fluids for responsive handling. All lights (headlights, brake lights) must function properly, and install new wiper blades for clear visibility. I always check battery charge to prevent starting issues mid-journey, and carry warning triangles and flashlights for emergencies. Spending 30 minutes on these checks brings peace of mind for safer, stress-free driving.

Young people love road trips, and I think car maintenance should be hassle-free but reliable. Check the tire pressure and adjust it according to the label on the door to avoid high-speed vibrations; replace the oil filter if it's dirty to save money and hassle. Test the brake system by pressing the pedal a few times—just make sure it responds promptly; ensure all lights are bright, especially the headlights for night driving. Wipers should clear the windshield properly for clear vision in the rain. Keep the spare tire fully inflated in the trunk and have a toolkit ready; test the air conditioning for both cooling and heating to ensure comfort on long drives. Pack some snacks and drinks for emergencies, ensuring a smooth and punctual journey. The whole process takes just 15 minutes—highly efficient.

I always prioritize family safety, and long-distance maintenance must be thorough. First, check if the tire pressure is appropriate, and ensure even wear to prevent blowouts. Spare tires and tools should be complete, and carry a warning triangle to prevent rear-end collisions. Fluids such as engine oil, coolant, and brake fluid should be at full levels to ensure smooth mechanical operation. Lights should be bright—test the headlights and taillights—and replace wipers to maintain a clear view. Inspect the engine for any unusual noises, and ensure the battery has enough charge for quick starts. Small details like tightening screws and securing the chassis to prevent bumps should be properly prepared. With everything ready, set off with peace of mind—safety first is always the top priority.

As a car enthusiast, I pay attention to comprehensive maintenance before every long trip. Tire balance and air pressure are adjusted to prevent high-speed wobbling. Fresh engine oil with appropriate viscosity is used, and the filter is replaced to keep the engine strong. Brake discs and pads are checked for wear, and the brake fluid is topped up to ensure responsive braking. All lights are tested to ensure they work, especially the fog lights which are useful. The cabin air filter is replaced for fresh and cool comfort. The battery voltage is checked to ensure it's normal and won't drain. Suspension bolts are tightened to prevent loosening. Wipers are checked for smooth and clear operation. Emergency tools are packed for contingencies. With all this done in half an hour, I can enjoy a worry-free and smooth journey.

I advocate for practical maintenance that saves both money and hassle. Before a long trip, check the tire pressure within the manual's range to avoid wasting fuel and tire wear. Bring an air pump kit for the spare tire to prevent roadside troubles. Ensure fresh and sufficient engine oil and coolant for smooth operation, bright lights, and test the brakes for safety. Clean wipers provide clear visibility. Test the battery charge to prevent starting failure, try the air conditioning for comfort, and set the navigation to avoid getting lost. Small investments yield big returns by preventing high repair costs. Pack some food and emergency supplies to be fully prepared for a worry-free journey.
