There is something special about a long road trip. The open road, changing scenery, spontaneous stops, and the freedom to choose your own route can make driving part of the adventure rather than simply a way to reach your destination.
But a great road trip can quickly turn into a stressful experience if your car is not ready for the journey.
Before loading your luggage and heading out, spend some time checking your vehicle. A few simple inspections can help you spot problems before they become breakdowns on the highway.
A Quick Pre-Trip Checklist
Before you pull out of the driveway, take a few minutes to go through this list:
| Check | What to Look For |
| Tires | Pressure, tread, damage and spare |
| Engine oil | Correct level and service interval |
| Fluids | Coolant, brake, transmission and washer fluid |
| Brakes | Noise, vibration and pedal feel |
| Battery | Condition, corrosion and starting performance |
| Lights | Headlights, brake lights and indicators |
| Wipers | Damage and streaking |
| Belts & hoses | Cracks, cuts or bulges |
| A/C | Cold and consistent airflow |
| Emergency kit | Tools, water, charger and first aid |
Here are 10 important things to check before a long road trip.
1. Check Your Tires
Your tires are the only part of your car constantly touching the road, so they deserve special attention before any long journey.
Check all four tires for:
- Correct tire pressure
- Uneven tread wear
- Cuts or cracks
- Bulges or damage on the sidewalls
- Nails or other objects
- Sufficient tread depth
Always check tire pressure when the tires are cold and use the pressure recommended by your vehicle manufacturer. You can usually find the correct pressure on the driver’s door-jamb sticker or in the owner’s manual. The number printed on the tire sidewall is generally the tire’s maximum pressure, not the recommended pressure for your vehicle.
Don’t forget the spare tire. If your car uses a temporary spare or a tire repair kit instead, make sure you know where it is and how to use it.
2. Check the Engine Oil and Other Fluids
Long-distance driving puts additional demands on your engine, especially when you’re driving in hot weather, climbing mountains, or carrying a fully loaded vehicle.
Before leaving, check the engine oil level and make sure you’re not approaching a scheduled oil change. You should also check other important fluids, including:
- Engine coolant
- Brake fluid
- Transmission fluid
- Power steering fluid, if applicable
- Windshield washer fluid
If you notice a fluid level dropping unusually quickly or see fluid underneath your parked car, don’t simply top it up and leave. It could indicate a leak that should be inspected before the trip.
If you’re unsure how to check any of these fluids, your owner’s manual is the best place to start.
3. Inspect the Brakes
A long road trip can involve hundreds of miles of braking, particularly if your route includes mountains, busy cities, or heavy traffic.
Pay attention to how your brakes feel before the journey.
Warning signs include:
- Grinding or squealing noises
- Vibrations when braking
- A brake pedal that feels unusually soft
- The car pulling to one side when braking
- A brake warning light on the dashboard
If you notice any of these symptoms, have the braking system inspected by a qualified professional before setting off. AAA recommends checking the brake system, including pads, rotors and related components, as part of road-trip preparation.
Brakes are not something to gamble with when you’re about to spend hours on the highway.
4. Test the Battery
A weak battery can turn a relaxing road trip into an unexpected roadside stop.
Before your trip, check the battery for obvious signs of damage or corrosion and make sure the connections are secure. If the battery is several years old or you’ve noticed slow engine cranking recently, consider having the battery and charging system professionally tested.
This is especially important when traveling through extreme temperatures. Heat can accelerate battery deterioration, while very cold conditions can make a weak battery even more difficult to start.
A portable jump starter is also a useful addition to your emergency kit.
5. Check All Lights
Good visibility isn’t only about seeing the road. Your lights also help other drivers understand what you’re doing.
Walk around your car and test:
- Headlights
- High beams
- Brake lights
- Turn signals
- Hazard lights
- Reverse lights
- Fog lights, if equipped
Ask someone to press the brake pedal while you check the brake lights, or use a reflection to inspect them yourself.
Also clean dirty headlights and make sure your windshield is clean. Being able to see clearly becomes even more important when driving at night or in rain, fog, dust, or other poor conditions.
6. Inspect the Wipers and Windshield
A clean windshield can make a surprisingly big difference during a long drive.
Check your windshield for cracks or chips and inspect the wiper blades. If they leave streaks, skip sections of glass, chatter across the windshield, or look cracked and damaged, replace them before leaving.
Fill the windshield washer reservoir as well.
Don’t underestimate this check. A sudden rainstorm can make a worn-out set of wipers a genuine safety problem. NHTSA specifically recommends inspecting wiper blades before long trips.
7. Look Under the Hood
You don’t need to be a professional mechanic to perform a basic under-hood inspection.
With the engine off and cool, look for anything that appears unusual.
Check for:
- Loose or damaged hoses
- Cracked belts
- Corrosion around the battery
- Visible fluid leaks
- Damaged wiring
- Unusual smells
- Low fluid levels
Rubber belts and hoses can deteriorate over time, and high temperatures can accelerate that process. If you see cracks, cuts, bulges, or other obvious damage, have the vehicle inspected before the trip.
If your car has been showing warning lights or unusual noises, don’t assume they’ll disappear once you’re on the highway. Deal with them before departure.
8. Check Your Air Conditioning
For a summer road trip, especially through a hot region, air conditioning isn’t just about comfort.
Start the car and make sure the A/C is producing cold air and working normally. If the system is weak, makes unusual noises, or stops cooling after a short period, have it checked before your journey.
This is particularly important when traveling with children, older passengers, or pets.
NHTSA also recommends checking A/C performance before summer travel because extreme heat can create additional risks for people inside the vehicle.
For a long journey, a comfortable cabin can make a big difference in driver fatigue and overall enjoyment.
9. Prepare an Emergency Kit
Even a well-maintained car can experience an unexpected problem.
That’s why it’s smart to keep an emergency kit in the vehicle.
Consider carrying:
- Phone and charging cable
- Portable power bank or jump starter
- Flashlight
- Tire pressure gauge
- Tire inflator
- Jumper cables
- First-aid kit
- Reflective warning triangles or similar roadside warning equipment
- Basic tools
- Drinking water
- Non-perishable snacks
- Work gloves
- Spare windshield washer fluid
- Necessary personal medications
If you’re traveling through remote areas, add extra water and make sure someone knows your route.
NHTSA recommends carrying essentials such as a phone and charger, first-aid supplies, flashlight, jumper cables, tire equipment, food and water.
The goal isn’t to prepare for every possible disaster. It’s simply to make a minor problem easier to handle until help arrives.
10. Check the Route, Weather and Your Vehicle’s Documents
Your car isn’t the only thing that needs preparation.
Before leaving, check your planned route and look at the expected weather. If you’re traveling through remote areas, mountainous roads, deserts, or unfamiliar highways, identify fuel stations and safe stopping points along the way.
It’s also worth checking:
- Vehicle registration
- Insurance documents
- Driver’s license
- Roadside assistance information
- Toll requirements
- Navigation maps
- Hotel or accommodation details
- Any required permits or travel documents
Download offline maps if you’re traveling somewhere where mobile coverage may be unreliable. AAA also recommends checking weather and road conditions before setting out.
And don’t forget to check whether your vehicle has any outstanding safety recalls before a major trip.
Don’t Wait Until the Morning of the Trip
One of the biggest mistakes people make is checking everything a few hours before departure.
If you discover a worn tire or weak battery on the morning of your road trip, you may have to delay your plans—or worse, decide to travel anyway.
Instead, inspect your car several days before you leave. That gives you enough time to replace a tire, schedule maintenance, buy emergency equipment, or fix a problem.
For older vehicles, high-mileage cars, or vehicles that haven’t received regular maintenance, a professional pre-trip inspection can be particularly worthwhile.
Final Thoughts
A successful road trip starts before you turn the key.
You don’t need to spend an entire weekend preparing your car. A careful inspection of the tires, fluids, brakes, battery, lights, wipers and other essential systems can help you catch problems before they become expensive or dangerous surprises.
Once your vehicle is ready, pack your emergency kit, check the route, look at the weather, buckle up and enjoy the journey.
After all, the best road trips are the ones where the only unexpected stops are the ones you actually wanted to make.
