Summer Road Trip Checklist: 7 Things to Inspect Before You Drive (Ace Roadside)
Summer is peak road trip season — and peak breakdown season. Between the heat, the extra miles, and the fully loaded trunk, your car works harder in July and August than at almost any other time of year. The good news? Most summer breakdowns are preventable with a 20-minute inspection before you leave the driveway.
Here are the 7 things you should check before your next road trip, plus what to do if something goes wrong once you're already on the road.
1. Tires: Pressure, Tread, and Spare
Heat causes tire pressure to rise, and worn tread combined with hot asphalt is one of the most common causes of summer blowouts.
Check pressure when tires are cold (before driving), and compare it to the number on the driver's door jamb — not the number on the tire itself.
Run the penny test on your tread: if you can see all of Lincoln's head, it's time to replace.
Don't forget the spare. A flat spare is just as useless as no spare at all.
If you find a problem you can't fix yourself, mobile tire services can come to you and get you back on the road without a trip to the shop.
2. Battery Health
Most people associate dead batteries with winter, but extreme heat is actually harder on battery life. High temperatures accelerate fluid evaporation and internal corrosion, which is why summer is a leading season for battery failure.
Look for corrosion around the terminals.
If your battery is more than 3 years old, consider having it load-tested before a long trip.
Keep jumper cables in your trunk regardless — or know that a battery jump start is one tap away if you get stranded.
3. Coolant and Cooling System
Overheating is the #1 roadside call during summer months. Your cooling system is what stands between a normal drive and a smoking hood on the shoulder of the highway.
Check coolant level when the engine is cold.
Look under the car for any signs of leaking (a sweet smell or puddle near the front of the car is a red flag).
Never open a hot radiator cap — if you do overheat, pull over, turn off the engine, and let it cool completely before checking anything.
4. Oil Level and Condition
Long highway miles in summer heat put extra strain on your engine oil. If it's been a while since your last oil change, do it before you leave, not after you get back.
Check the dipstick for level and color — oil should be amber to brown, not dark and gritty.
If you're due (or overdue), a mobile mechanic can handle an oil change at your home or office before you ever hit the freeway.
5. Brakes
More weight in the car (passengers, luggage, a roof box) means longer stopping distances. Combine that with mountain or canyon driving on many summer trips, and worn brakes become a real safety issue.
Listen for squealing or grinding.
If your car pulls to one side when braking, or the pedal feels soft, have it inspected before departure.
6. Fluids and Belts
Pop the hood and do a quick visual check of windshield washer fluid, power steering fluid, and the condition of your belts and hoses. Cracked or glazed belts are more likely to snap in extreme heat, which can leave you stranded far from home.
7. Emergency Kit and a Plan
Even a perfectly maintained car can run into trouble — a nail in the tire, a dead battery, an empty tank on a stretch of highway with no gas station in sight. Pack:
Water and snacks for passengers
A phone charger or battery pack
A basic emergency kit (flashlight, reflective triangle, first-aid supplies)
A saved contact for roadside help, so you're not searching for a number while stressed on the shoulder
This last one matters more than people think. Cell service is spotty in a lot of the places people road trip through, and searching for "tow truck near me" at 2% battery in the middle of nowhere is not the plan you want.
What to Do If Something Goes Wrong Anyway
Even with a full inspection, things happen — that's what makes it a road trip. If you find yourself stuck on the side of the road, Ace Roadside offers 24/7 emergency assistance, including:
