Can a Car Handle 12 Hours of Continuous Driving?

Continuous driving for 12 hours is not advisable for a car. Driving for such a long duration can lead to dizziness and fatigue, which significantly increases the risk of accidents. Therefore, it's essential to balance work and rest. Driving fatigue refers to the decline in driving skills due to the physiological and psychological imbalance that occurs after prolonged continuous driving. Below are some precautions for driving on highways: 1. Drive in the designated lane: Highways have clearly marked lanes for different types of vehicles, such as large trucks and small cars. After overtaking, promptly return to your designated lane and avoid occupying other lanes for extended periods. Additionally, emergency lanes should not be occupied unless under special circumstances. 2. Maintain a safe speed and avoid speeding: The dangers of speeding are well-known, as it can lead to irreversible consequences, whether on local roads or highways. 3. Maintain a safe following distance: Under normal conditions, with dry roads and good braking, the following distance (in meters) should not be less than the speed (in km/h). For example, at 80 km/h, maintain at least 80 meters, and at 100 km/h, maintain at least 100 meters. Always pay attention to roadside distance markers. In rainy, foggy, snowy, or wet road conditions, double the following distance. 4. Observe traffic signs: Always be aware of roadside and overhead signs and markings. Drive slightly to the right to avoid running over the right lane divider, allowing sufficient lateral distance for overtaking vehicles. 5. Do not occupy the emergency lane unnecessarily: Traffic accidents are inevitable on highways. If other vehicles' accidents block the roadway, avoid occupying the emergency lane, as it may hinder rescue operations. 6. Avoid fatigued driving and take timely breaks: Fatigued driving is extremely dangerous on highways. Fatigue reduces reaction time, making it difficult to respond correctly to sudden situations.
I often ponder about automotive mechanical performance. Modern vehicles are designed to be quite durable, and theoretically, a car can handle 12 hours of continuous driving, but the devil is in the details. Engine temperatures can spike, especially in older cars or those with neglected cooling systems, causing fluids to overheat and age prematurely, while tire wear can double. Brake components may overheat and fail if friction is severe. For long-distance driving, it's advisable to check coolant and oil levels before departure, take breaks every 4 hours to let the engine rest, and monitor tire pressure and temperature to avoid continuous full-load operation. In summer, extra attention should be paid to the strain on the air conditioning compressor. In short, the car can handle it, but don't push it to the limit—caution ensures longevity. I've seen plenty of breakdowns mid-journey; prevention is always better than regret.
As a safe driving advocate, I believe the focus shouldn't solely be on the vehicle, but more importantly on the driver. Fatigued driving poses extremely high risks - after 12 hours of continuous driving, a person's reactions become sluggish and they may even doze off, significantly increasing accident probability. Regarding the vehicle itself, with proper maintenance the engine and transmission can barely endure, but tires are prone to blowouts due to prolonged friction, especially at high speeds. Continuous battery power supply may overload, and any dashboard abnormalities mean you should stop immediately. I strongly recommend segmented driving - take 20-minute breaks every 2 hours to stretch and inspect your vehicle, protecting both yourself and your car. Remember safety first - many disasters stem from minor oversights, so don't risk pushing through in one go.
