There's a big difference between a car that handles your daily 15-minute commute just fine and one that's ready for a 500-mile highway trip. Your daily commute is forgiving — a slightly low tire, aging wiper blades, or an overdue oil change won't strand you when you're 5 minutes from home. On a road trip, those same issues can leave you on the shoulder in an unfamiliar state, waiting for a tow truck.
This checklist takes about 20 minutes to go through and can prevent the most common road trip breakdowns. Do it a week before your trip so you have time to address anything that needs attention.
One Week Before: Maintenance Check
Oil and Fluids
If your oil change is due within the next 2,000 miles, get it done before the trip. Long highway driving at sustained speeds is harder on oil than city driving. While you're at it (or while the shop has it), have them check:
- Coolant level and condition — should be at the proper mark and the right color (not rusty or milky)
- Brake fluid — should be between MIN and MAX on the reservoir
- Transmission fluid — if your car has a dipstick for it, check the level and color (should be pink/red, not brown or burnt-smelling)
- Power steering fluid — if applicable to your vehicle
- Windshield washer fluid — top it off completely. Bring an extra jug in the trunk.
Tires
Tires are the number one cause of road trip breakdowns. Check all four plus the spare:
- Pressure: Inflate to the door jamb specification. Don't forget the spare — check its pressure too.
- Tread depth: Use the penny test — insert a penny head-first into the tread. If you can see all of Lincoln's head, you need new tires. For a long trip, you want at least 4/32" of tread (the penny test checks 2/32", which is the legal minimum).
- Condition: Look for cracks in the sidewall, bulges, uneven wear, or nails/screws embedded in the tread. Any of these warrant a trip to the tire shop before your road trip.
Brakes
If your brakes squeal, pulse, or feel spongy, get them inspected. Mountain driving and stop-and-go traffic in unfamiliar cities are hard on brakes. You don't want to discover a problem on a steep downhill with a loaded car.
Belts and Hoses
Pop the hood and visually inspect the serpentine belt for cracks, fraying, or glazing. Squeeze the radiator hoses — they should feel firm but pliable, not rock-hard, mushy, or cracked. A belt or hose failure at highway speed causes immediate problems (overheating, loss of power steering, dead battery).
Battery
If your battery is more than 3 years old, have it tested. Most auto parts stores test batteries for free. A battery that starts fine in mild weather can fail in extreme heat or after sitting at a rest stop for a few hours.
Lights
Walk around the car and check every light: headlights (low and high beam), tail lights, brake lights (have someone press the pedal while you look), turn signals, and reverse lights. A burned-out light is an easy fix at home but a potential traffic stop in another state.
Day Before: Final Prep
Emergency Kit
Make sure your car has a basic emergency kit. At minimum: jumper cables (or a portable jump starter), flashlight, first aid kit, basic tools, and a phone charger.
Navigation
Download offline maps for your route. Cell service can be spotty on rural highways. Having your route available offline means you won't be guessing at intersections in the middle of nowhere.
Documents
Make sure you have in the car: driver's license, registration, insurance card, and your roadside assistance contact information. Some states require physical copies of registration and insurance even if your state allows digital versions.
Wiper Blades
If they streak or skip, replace them. A sudden rainstorm on an unfamiliar highway with bad wipers is genuinely dangerous. Replacing wipers takes 5 minutes.
On the Road: Driving Tips
- Check tire pressure every morning of a multi-day trip. Temperature changes overnight can drop pressure.
- Stop every 2-3 hours. Rest stops are good for you and the car. Walk around, stretch, and do a quick visual check of your tires.
- Watch the temperature gauge. Highway driving in hot weather with a loaded car and A/C running pushes the cooling system hard. If the gauge starts climbing, turn off the A/C and turn on the heater to draw heat from the engine.
- Don't ignore new noises or smells. If something changes during the drive — a new vibration, a smell, a warning light — pull over and investigate. Catching a problem early is always cheaper than pushing through it.
