Make sure you check:

• Tyres: Your tyres are your car's only contact with the road, so their condition is crucial. Check for adequate tread depth and look for any signs of wear or damage. Ensure all tyres, including the spare, are properly inflated to the recommended pressure.
• Brakes: Good brakes are essential for your safety. Listen for any unusual noises when braking, such as squealing or grinding. It's wise to have your brakes checked by a professional to ensure they are working effectively.
• Fluids: Check all the essential fluids, including oil, coolant, brake fluid, power steering fluid, and windshield washer fluid. Top them up if necessary and consider having the oil changed if it's due.
• Lights and Signals: Ensure all lights and indicators are functioning correctly, including headlights, brake lights, and turn signals. Replace any burned-out bulbs to maintain visibility and safety on the road.
• Battery: Inspect your battery for any signs of corrosion or damage. If your battery is older or you’ve had trouble starting your car, consider having it tested to avoid being stranded on your trip.
• Air Conditioning and Heating: Check that your AC and heating systems are working properly, especially if you're traveling to regions with extreme temperatures.
• Wipers and Windows: Ensure your windshield wipers are in good condition for clear visibility. Clean all windows inside and out for an unobstructed view of the road.
• Emergency Kit: Pack an emergency kit that includes a first aid kit, flashlight, jumper cables, basic tools, and a spare tire. It's better to be prepared for any unexpected situations.
