Before embarking on a long highway journey, it's crucial to perform a series of essential checks. These checks ensure the safety and smooth operation of your vehicle, whether it's a new or an older car.

Here are the steps you should follow, and remember to do these before every long trip:

1. Check the Oil Level:

- Start by confirming if your car has enough oil.

- When the engine is cold, pull out the oil dipstick, wipe it clean, reinsert it, and then pull it out again.

- If the oil level is below the indicated scale, you need to add more oil.

2. Inspect the Coolant Level:

- Locate the translucent coolant reservoir inside the cabin.

- Check if the coolant level falls within the normal range indicated on the reservoir.

- If it's below this range, add more coolant as needed.

3. Evaluate Brake Pad Thickness:

- Examine your brake pads to ensure they are thick enough.

- Look through the gaps in the wheel spokes.

- If the pads are sufficiently thick, there's no cause for concern.

- If they aren't visible, it's time to replace them.

4. Examine Tire Condition:

- Carefully inspect your tires for any side scratches, cracks, or excessive wear.

- Replace tires with serious cracks or worn center grooves, as they can be unsafe for highway driving.

- If the tires are in good condition with adequate tread, there's no need for immediate replacement.

- Look for any nails or foreign objects stuck in the tires; if found, have them repaired.

5. Check Tire Pressure:

- Verify the tire pressure, either using a tire pressure monitoring system or manually.

- Ensure the tire pressure matches the recommended levels specified in your vehicle's manual.

6. Inspect Lights:

- Turn on all vehicle lights, including fog lights and taillights.

- Step outside the car to check if all lights are functioning properly.

- Ensure that no lights are burnt out or malfunctioning.

7. Verify Windshield Wiper and Washer Fluid:

- Test the windshield wipers by spraying washer fluid onto the windshield.

- Ensure that the wipers are effectively clearing the windshield without any issues.

- Make sure there is an adequate supply of washer fluid in the reservoir.

After completing these checks and confirming that your car is in good condition, you are ready to embark on your long-distance highway journey. However, when driving on highways, consider the following tips:

1. Always fasten your seatbelt, including all passengers in the vehicle, to maintain safety and focus while driving.

2. Maintain a safe distance from large trucks to avoid sudden lane changes, flat tires, or debris falling from them.

3. Take regular breaks, approximately every two to three hours, during extended highway drives to combat driver fatigue.

4. Be cautious when encountering wet road surfaces; it might not just be water but also oil. Slow down and use the throttle wisely to maintain control.

5. When driving on snowy or icy roads, try to follow the tracks left by the vehicle in front of you, but exercise caution and don't follow blindly, as road conditions may change.

By following these guidelines, you can ensure a safe and enjoyable long-distance highway journey while minimizing potential issues with your vehicle.
