A breakdown in your hometown is annoying. A breakdown 500 miles from home is a 2-day vacation killer. Run through these 12 checks the day before you leave - 90 minutes that's worth every second.

⚠ ImportantTop up your fluids the day before, not the morning of. A leaking gasket shows up overnight as a fresh puddle - much better to find it in the driveway than at a rest stop.

❓ Frequently Asked Questions

How soon before a road trip should I prep the car?
1-3 days before. Any sooner and you might miss a slow leak; the morning of is too late if you find something wrong.
Should I get an oil change before a long road trip?
Only if you're within 1,000 miles of due. A fresh change isn't magic - it's the level and condition that matter.
Do I need to take my car to a shop for pre-trip inspection?
For most owners, no. The 12 checks above cover 95% of what a shop checks. A shop adds value if you're unsure or haven't had recent service.
What if I find a problem the day before leaving?
Anything critical (red on this list) - delay the trip or rent a car. Important issues (orange) can usually be addressed same-day or limped to your destination.
How often should I stop and re-check the car on a long drive?
Every fuel stop, walk around once. Look for low tires, leaks under the car, hot smells. Takes 30 seconds.
Is roadside assistance worth it for a road trip?
For most people yes. A single tow from an interstate easily covers a year of AAA. Many credit cards include free coverage - check before paying.
