Road Trip Prep: The Complete Pre-Trip Car Checklist

Tire failure is the leading cause of highway breakdowns. Under-inflated tires overheat at sustained speeds, and worn tread cannot channel water during rain.

• Check pressure when tires are cold (before driving)
• Set to the pressure listed on your driver's door jamb, not the tire sidewall
• Use a penny to check tread: if you see Lincoln's full head, tires need replacement
• Inspect sidewalls for cracks, bulges, or cuts from potholes
• Do not forget the spare tire, verify it is inflated and the jack works

Need a tire rotation before the trip? Follow our tire rotation guide.

Long highway drives put more sustained load on your engine than city driving. Starting with fresh, full oil prevents overheating and premature wear.

• Pull the dipstick on a cold engine, wipe, reinsert, and read the level
• Oil should be between the min and max marks
• Check color: golden or light brown is good, dark black or gritty means it is time to change
• If your next oil change falls within the trip mileage, change it now
• Bring one quart of the correct weight oil for top-offs during the trip

Due for an oil change? See our complete oil change guide.

Your cooling system works hardest during long drives in warm weather. Low or degraded coolant is the fastest path to an overheated engine on a summer highway.

• Check the coolant reservoir when the engine is cold (never open a hot radiator cap)
• Level should be between the min and max lines on the reservoir
• Coolant should be its original color (green, orange, or pink), not brown or rusty
• Top off with the correct type for your vehicle if low
• Look under the car for coolant puddles, which signal a leak

Not sure which coolant to use? Check our coolant types guide. Seeing leaks? Read our leak diagnosis guide.

Mountain driving, towing, and loaded vehicles put extra stress on brakes. Starting a long trip with thin pads or low fluid is a safety risk you can easily avoid.

• Look through wheel spokes to visually inspect brake pad thickness
• Minimum safe pad thickness is 3 to 4mm (about the thickness of two pennies)
• Check brake fluid level in the master cylinder reservoir under the hood
• Fluid should be clear to light amber, not dark brown or black
• Listen for squealing or grinding during a test drive around the block

Pads looking thin? Our brake pad replacement guide walks you through the swap.

A battery that starts your car fine for 10-minute commutes can fail on a 6-hour highway drive. Sustained accessory load (GPS, phones, AC) drains a weak battery fast.

• Use a multimeter: should read 12.4V or higher with the engine off
• With the engine running, should read 13.7V to 14.7V (charging system working)
• Inspect terminals for white or green corrosion buildup
• Clean corroded terminals with baking soda and water
• Check the battery age sticker: most batteries last 3 to 5 years
• If over 4 years old or testing below 12.4V, replace before the trip

For full diagnostics, see our battery troubleshooting guide.

A broken serpentine belt will kill your power steering, AC, and alternator simultaneously, leaving you stranded. Rubber degrades faster in heat, making this critical for summer trips.

• Inspect the serpentine belt for cracks, fraying, or glazing on the ribbed side
• Press on the belt: it should have no more than half an inch of deflection
• Squeeze radiator hoses: they should feel firm but flexible, not spongy or brittle
• Look for bulges, cracks, or wet spots on any hose
• Check hose clamps for tightness and corrosion

Belts over 60,000 miles should be replaced. See our timing belt guide if your vehicle uses one.

A burned-out tail light or brake light can earn you a ticket in an unfamiliar state and create a safety hazard. Checking lights takes five minutes and saves real headaches.

• Turn on headlights and check both low and high beams
• Verify both tail lights and both brake lights work (have someone press the pedal)
• Test all four turn signals and hazard flashers
• Check reverse lights by shifting to reverse briefly
• Clean foggy headlight lenses for maximum visibility

Need a bulb replacement? See our headlight bulb guide. Hazy lenses? Try our headlight restoration guide.

Driving through rain or road spray with streaky wipers is dangerous and exhausting. Fresh blades and a full washer fluid reservoir make all the difference on long drives.

• Test wipers: if they streak, chatter, or skip, replace them
• Wiper blades last 6 to 12 months depending on climate and use
• Fill the washer fluid reservoir completely (use bug remover formula for summer)
• Test the washer spray pattern: nozzles should hit the windshield evenly
• Clean the inside of the windshield for glare-free night driving

Driving 8 hours in summer heat without AC is miserable and potentially dangerous. Test the system now so you have time to address any issues before departure.

• Turn the AC to maximum cold and let it run for 5 minutes
• Air should blow noticeably cold within 2 to 3 minutes
• Check for unusual smells (musty = dirty cabin filter, sweet = coolant leak)
• Listen for clicking or grinding noises from the compressor
• If cooling is weak, the system may need a refrigerant recharge

AC not cold enough? Our AC diagnosis guide covers the fix. Also see our summer car prep guide for heat-specific maintenance.

Even with a perfectly maintained car, other drivers, weather, and road debris can create emergencies. A well-stocked kit turns a potential crisis into a manageable inconvenience.

• Jumper cables or a portable jump starter (the portable option is easier solo)
• Reflective warning triangles or road flares
• First aid kit with bandages, antiseptic, and basic medications
• Flashlight with fresh batteries or a rechargeable model
• Phone charger and portable battery bank
• Basic tool kit (pliers, screwdrivers, adjustable wrench, duct tape)
• Water and non-perishable snacks for each passenger
• Blanket (useful for warmth or as a ground cover during tire changes)
