Embarking on a long road trip can be an exciting adventure, whether you are going on a family trip or driving cross country, it's crucial to ensure your car is in good condition before you hit the road. No one wants to be stranded with a broken-down car in the middle of nowhere. By following some simple precautions, you can ensure your safety and make your journey more enjoyable.

1. Inspect Wheels & Tires

The first and perhaps most important check must be where the vehicle and the road meet. Inspecting the vehicle wheels and tires are important because it may help prevent potential safety issues and ensure predictive handling during emergency evasive maneuvers. You should inspect your wheels and tires for the following condition and safety related issues:

• Tire Condition: Check the condition of your tires for any signs of wear, damage or bald spots. Uneven tire wear is a sign of possible alignment related issues and should be inspected by a professional. Also, check how much tire tread is left over on your tire as it tends to wear over time. Insufficient tread can be dangerous, especially in wet or snowy conditions. The general rule is that if the tread depth is less than 2/32 of an inch, it's time to replace your tires.
• Tire Pressure: Proper tire pressure is crucial for safety and fuel efficiency. Check the tire pressure using a reliable gauge and inflate the tires to the recommended pressure, which is usually found on a sticker inside the driver's door jamb, on the tire sidewall or in the owner's manual. If the vehicle comes with a spare tire don’t forget to check it as well.  
• Wheel Balance and Lug Nuts: By sure to check all the wheel lug nuts to ensure they are torqued to the proper factory specifications. Your lug nut torque specifications should be found in your vehicle’s owner’s manual. This step is especially important if the car has had any recent service performed where wheels were removed. A re-torque may be required on some wheels. Take the car for a short test drive. Check for any vibration if, your car pulls to one side it might be a sign of misaligned or unbalanced wheels. Have a professional check and correct the alignment and balance before your trip.

2. Check Fluid Levels

Another vital part of getting the vehicle ready for a long trip is to ensure that all of the fluids meet recommended levels and conditions. Check the following system fluids:

• Engine Oil: Start by checking the engine oil level. Low oil can cause serious engine damage, especially at high temperatures. If the oil is low, top it up with the appropriate type of oil recommended by your car’s manufacturer. If your car comes with a dip stick be sure to also check the color and condition of the oil. If it looks very dark/black or has contaminants consider doing an oil change prior to your trip.
• Coolant: The coolant, also commonly known as antifreeze, is essential for maintaining the engine's temperature. Check the coolant level and ensure it is within the recommended range. If it's low, top it up with a 50/50 mixture of manufacturer recommended coolant and water.
• Brake Fluid: The brake fluid is crucial for the proper functioning of your braking system. Check the brake fluid level and top it up if necessary. ONLY use manufacturer designated brake fluid. If the fluid looks dirty or has been in the car for more than two years, consider bringing it to a mechanic shop for a brake fluid flush.
• Windshield Washer Fluid: Windshield fluid is amongst the most overlooked fluids however, it serves a very important function, cleaning the windshield allowing the driver to get an unabstracted view of the road. Top up the windshield washer fluid to ensure you have enough for cleaning your windshield during the trip. Do not dilute washer fluid with water and use a solution that is appropriate for the weather conditions you expect to encounter.
• Transmission Fluid: For automatic transmissions, check the transmission fluid level. If it's low, top it up with the recommended fluid. Manual transmissions may have a dipstick for checking the fluid level.
• Power Steering Fluid: Most modern vehicles have replaced hydraulic power steering systems with electric ones however, if your vehicle comes with hydraulic power steering system be sure to check the power steering fluid level before heading out.

3. Inspect the Brakes

The braking system is one of the most critical safety features of your car. On most cars with alloy wheels the braker rotors and pads are clearly visible without removing the wheels. Visually check the brake pads and rotors for wear. If the pads are thin or the rotors are grooved, have them replaced. Also, check the brake lines for any leaks or damage. If you notice any issues, have the brakes serviced by a professional.

4. Check Car Battery

A dead battery can leave you stranded, so it’s important to ensure it’s in good condition. Check the battery terminals for corrosion and clean them if necessary. If the vehicle is slow to start especially when it is cold, it may be due to a worn or damaged battery. If the battery is 5 years or older it is generally recommended that it is replaced.

5. Check the Lights

Make sure all your lights are working properly, including the headlights, taillights, turn signals, brake lights and hazard lights. You may need to have someone press on the brakes while another person inspects to make sure the rear brake lights are turning out and do not have any burned out bulbs. Replace any burned-out bulbs and clean the lenses to ensure maximum visibility.

6. Inspect Engine Belts and Hoses

Look under the hood, check for any signs of any fluid leaks. Check the belts and hoses for any signs of wear, such as cracks, fraying or bulges. A broken belt can cause the engine to overheat or fail, while a burst hose can lead to a loss of coolant. If you notice any issues, have the belts and hoses replaced before your trip.

7. Check the Air Filter and Cabin Filter

A dirty air filter can reduce engine performance and fuel efficiency. Check the air filter and replace it if it’s dirty or clogged. Similarly, a dirty cabin filter can affect the quality of the air inside the car.

8. Inspect the Suspension

The suspension system helps by improving handling while creating a smooth and comfortable ride. As you take the vehicle for a test drive listen for any unusual suspension noises. Check for any signs of excessive wear or leaking damaged shocks, struts and broken springs. If you notice any issues, have the suspension system inspected and repaired by a professional.

9. Check the Wipers and Defrosters

Ensure that your windshield wipers are in good working condition and can effectively clear rain, snow and debris from the windshield. Replace windshield wiper blades if the rubber feels too hard, sticky, torn or if they appear worn. If you are driving during the winter months or in any cold climate it is advisable to check the defrosters to ensure they are working properly.

10. Pack an Emergency Kit

Even with thorough preparation, unexpected issues can arise. Pack an emergency kit that includes:

• Jumper cables or a fully charged battery jumper pack
• Spare tire and jack
• Tool kit
• First aid kit
• Flashlight with extra batteries
• Reflective triangles or flares
• Blanket and warm clothing
• Non-perishable food and water
• Cell phone charger

Preparing your car for a long trip is essential for ensuring a safe and enjoyable journey. By checking the fluids, tires, battery, brakes, and other critical components, you can minimize the risk of breakdowns and ensure your car is in top condition. Don’t forget to pack an emergency kit and plan your route carefully. With these steps, you can hit the road with confidence and peace of mind. Safe travels!
