Key Takeaways

Tyre pressure and tread depth are the single most important things to check before a long drive.
Fluid levels — oil, coolant, and washer fluid — should be verified the evening before departure.
A basic emergency kit in the trunk can make a breakdown far less stressful and potentially safer.
Most of these checks take under 30 minutes total and require no special tools.
A problem caught at home is always cheaper and easier to fix than one found on the roadside.

Why a Pre-Trip Check Is Worth Your Time

Most breakdowns don't come out of nowhere. A flat tyre, an overheating engine, or a dead battery usually gives warning signs first — you just have to know where to look. Running through a quick pre-trip check before a long drive is one of the most practical things you can do as a car owner.

This checklist is designed for the average driver, not a mechanic. None of these checks require lifting the car or special equipment. If you work through them the evening before a long journey, you'll catch most potential problems while you still have time and options. For a broader look at what to inspect before any journey, including a full walkround guide, see our dedicated safety resource.

Once you're confident the car is ready, you'll also want to think about driver fitness. Long-distance driving and fatigue management is a separate challenge — and one worth planning for before you set off.

Required

Tyre Pressure Gauge

Lets you accurately read each tyre's pressure so you can inflate or deflate to the correct level.

Optional

Portable Tyre Inflator

Allows you to top off tyre pressure at home without driving to a gas station.

Required

Flashlight or Work Light

Helps you inspect tyres, check fluid levels, and look under the hood if you're doing this in low light.

Required

Clean Rag or Paper Towels

Needed to wipe the oil dipstick clean for an accurate reading.

Required

Jumper Cables or Jump-Start Pack

Essential emergency equipment in case of a dead battery on the road.

The Full Pre-Trip Checklist

Work through these groups in order. The checks at the top matter most — don't skip them in favor of the optional items at the bottom.

Tyres

Check tyre pressure on all four tyres (plus the spare) using a gauge, and inflate to the level shown in your owner's manual or door jamb sticker — not the number printed on the tyre sidewall. Must
Inspect tread depth on each tyre — insert a quarter into a tread groove with Washington's head pointing down; if you can see the top of his head, the tread is getting dangerously low. Must
Look over each tyre sidewall for bulges, cracks, or embedded objects like nails or screws. Must
Confirm the spare tyre is present, properly inflated, and that you have the jack and lug wrench accessible. Should

Fluids

Check engine oil level with the dipstick — wipe it clean, reinsert fully, then pull it again and read against the min/max markers. Must
Check coolant level in the overflow reservoir (never open the radiator cap on a warm engine) and top off with the correct coolant type if it's below the minimum line. Must
Fill the windshield washer fluid reservoir — it runs out faster than you expect on a highway drive. Should
Verify brake fluid is between the min and max marks on the reservoir; a notably low level can indicate brake pad wear and warrants a mechanic visit. Should

Lights and Visibility

Test all exterior lights — headlights (low and high beam), tail lights, brake lights, turn signals, and reverse lights — by walking around the car while a second person operates the controls, or by using reflections off a wall or garage door. Must
Switch on your wipers and washer jets to confirm the blades clear the windshield without streaking or skipping. Must
Check that all mirrors are clean and properly adjusted before you pull out of the driveway. Should

Under the Hood and Dashboard

Look at your dashboard for any warning lights — check engine, battery, tyre pressure, or temperature — and do not dismiss them before departure without understanding what triggered them. Must
Inspect belts visible under the hood for obvious cracking, fraying, or glazing, and flag any concerns to a mechanic before a long trip. Should
Confirm your fuel level and plan your first fill-up stop before the gauge drops below a quarter tank. Should

Emergency Kit

Verify that your emergency kit includes jumper cables or a jump-start pack, a reflective warning triangle or road flares, and a basic first aid kit. Should
Pack a flashlight with working batteries, a blanket, and a bottle of water in case of an extended roadside wait. Should
Keep your vehicle registration, insurance card, and roadside assistance information in an easy-to-find spot in the glovebox. Must
Download offline maps or confirm your GPS device is updated and charged before you leave cell coverage areas. Nice to have

Low Tyre Pressure Is a Real Safety Risk

Underinflated tyres handle and brake poorly, are more prone to blowouts at highway speeds, and reduce fuel efficiency. Tyre pressure drops naturally over time and with temperature changes — a tyre can lose about 1 PSI for every 10°F drop in outside temperature. Always check pressure when the tyres are cold (driven less than a mile), not after a highway run, for the most accurate reading.

What to Do If You Find a Problem

If a check reveals something wrong, don't ignore it and hope for the best. A tyre that's significantly underinflated, an oil level that's reading low, or a warning light that's on are all reasons to pause your plans and get the issue looked at first.

Most tyre shops and quick-lube centers can handle basic fluid top-offs and tyre pressure corrections on short notice. For anything involving warning lights or unusual noises, have a qualified mechanic take a look before you commit to a long haul.

Don't Ignore a Check Engine Light

A check engine light doesn't always mean something catastrophic, but it does mean something in the engine management system needs attention. Driving hundreds of miles with an undiagnosed fault can turn a minor issue into an expensive one. Have it scanned at an auto parts store or mechanic before committing to a long trip.
