What Should You Inspect on Your Vehicle Before Going on a Road Trip

What should you inspect on your vehicle before going on a road trip? Embarking on a road trip is an adventure that promises excitement and memorable experiences. However, the journey’s success heavily relies on the reliability and safety of your vehicle. A thorough vehicle inspection before setting off is crucial to ensure your trip is not only enjoyable but also safe. 

This precautionary step helps in identifying potential issues that could cause breakdowns or accidents during your journey. In this guide, we’ll walk through the key areas to inspect in your vehicle for optimal safety and efficiency, starting with the tires and then moving on to the engine and its fluids.


One of the first steps in vehicle inspection is checking the tire pressure. Tires with incorrect pressure can lead to decreased fuel efficiency, poor handling, and even blowouts. Use a reliable tire pressure gauge to check the pressure and adjust it to the PSI (pounds per square inch) recommended by the vehicle manufacturer, usually found in the owner’s manual or on a sticker inside the driver’s side door.

The depth of your tire tread is critical for maintaining good traction on the road. Use a tread depth gauge or the penny test (insert a penny into the tread with Lincoln’s head upside down; if you can see the top of Lincoln’s head, the tread is too shallow) to ensure your tires have adequate depth, typically 2/32 of an inch or more.

Examine each tire for signs of uneven wear, cracks, bulges, or foreign objects like nails. Uneven wear can indicate alignment or suspension issues, while cracks or bulges suggest the tire may need replacing. Don’t forget to check your spare tire. Ensure it’s properly inflated and in good condition. Also, verify that you have all the necessary tools (like a jack and tire iron) to change a tire if needed.

Engine and Fluids

Engine oil is essential for lubricating and cooling engine parts. Check the oil level using the dipstick and top up if it’s low. The oil should be a clear, amber color; if it’s dark and gritty, it might be time for an oil change.

Coolant keeps your engine from overheating. Check the coolant level in the reservoir and top up if needed. The coolant should be a vibrant color (green, red, or yellow) and free of debris. If it’s cloudy or has particles floating in it, a coolant system flush might be necessary.

Check the Brake Fluid, Transmission Fluid, and Power Steering Fluid. These fluids are vital for the respective systems’ operation and safety. Check the levels and look for any signs of leaks. Brake fluid should be clear and at the correct level in its reservoir. Transmission fluid should be checked with the vehicle running and should be a bright red color, not burnt or brown. Power steering fluid should also be at the appropriate level and free of contaminants.

Finally, ensure your windshield washer fluid is topped up. This fluid is crucial for maintaining visibility, especially when encountering bugs, dirt, or unexpected weather conditions.


The brakes are a critical safety component of any vehicle. Start by visually inspecting the brake pads and discs. The pads should have at least 1/4 inch of material remaining. If they are thinner, they need replacing. The discs should be smooth and uniform, without deep grooves or rough spots. Uneven wear or deep grooves indicate the need for resurfacing or replacing the discs.

During a drive, pay attention to any unusual noises or vibrations when applying the brakes. Squealing or grinding noises often signify that the brake pads are worn and need immediate attention. Vibrations, especially felt through the steering wheel, could indicate warped brake discs.

Test the responsiveness of your brakes in a safe, controlled environment. The vehicle should stop in a straight line and without delay when the brakes are applied. If the brake pedal feels spongy or you need to press it down further than usual, this could indicate air in the brake lines or a problem with the brake master cylinder.


Inspect the battery terminals for any signs of corrosion, which appears as a white, ashy substance. Corrosion can lead to poor electrical connections and trouble starting the vehicle. Clean any corrosion from the terminals and connectors using a wire brush and a mixture of baking soda and water if necessary.

Use a voltmeter or a multimeter to test the battery’s voltage. A healthy battery should typically read around 12.6 volts or more when the vehicle is off. If the voltage is lower, the battery may need charging or replacing. Consider a professional load test for a more accurate assessment of the battery’s health. Check that the battery cables are securely attached to the terminals and not frayed or damaged. Loose cables can cause starting issues, while damaged cables can be a potential fire hazard.

Lights and Electrical Components

Lights and Electrical Components

Functioning lights are essential for visibility and communication with other drivers. Check all exterior lights: headlights (both low and high beam), brake lights, turn signals, and hazard lights. Replace any burnt-out bulbs and clean the lenses for better visibility.

Ensure that all interior lights are working, including dashboard lights and indicators. Dashboard indicators should illuminate briefly when the vehicle is started and then turn off. If any lights stay on, this could indicate an issue that needs further investigation.

Finally, test the windshield wipers to ensure they effectively clear the windshield without streaking or skipping. Replace wiper blades if they are worn or damaged. Also, test the horn to ensure it’s loud and clear, as it’s an important tool for alerting other drivers or pedestrians in emergencies.

Belts and Hoses

The belts and hoses in your vehicle are crucial for the smooth operation of the engine and other systems. Begin by visually inspecting all accessible belts and hoses for signs of cracks, leaks, or wear. Rubber components can deteriorate over time, leading to failures. Pay special attention to the serpentine belt and radiator hoses, as these are particularly critical.

Ensure that the belts have the proper tension and are correctly aligned. A belt that’s too loose can slip, while one that’s too tight can cause premature wear on bearings and other components. Most modern vehicles have an automatic tensioner, but it’s still worth checking for proper tension.

Check for any signs of aging, such as rubber that’s become brittle or has started to fray. Belts and hoses that show these signs of wear should be replaced, even if they haven’t yet failed, to prevent breakdowns while on your road trip.

Air Conditioning and Heating System

Comfort is key on a road trip. Test both the air conditioning and heating systems to ensure they’re working efficiently. The A/C should blow cold air, and the heater should produce warm air. Issues with temperature control can indicate problems like low refrigerant levels or a malfunctioning thermostat.

Turn on the A/C and heating systems and listen for any unusual noises like banging, rattling, or hissing, which could indicate mechanical problems. Also, be aware of any unusual smells—musty odors can suggest mold in the system, while a sweet smell might indicate a coolant leak.
