To prevent car breakdowns while traveling, regular maintenance is crucial. Ensure your vehicle is in good condition by checking fluid levels (engine oil, coolant, brake fluid), tire pressure, and the battery before starting your trip. Replace old or worn-out parts such as belts, hoses, and spark plugs, and always have the vehicle inspected by a mechanic for any potential issues. Make sure your tires are properly inflated and have sufficient tread for safety. Additionally, carry essential items like a spare tire, jack, jumper cables, and basic tools in case of emergencies. Keep your gas tank at least half full to avoid fuel pump issues and prevent running out of fuel in remote areas. Lastly, avoid overloading your car, drive cautiously, and follow speed limits to reduce strain on your vehicle, ensuring it remains reliable throughout your journey.
