Why a Pre-Trip Check Matters More Than Most Families Realise

Most breakdowns on long drives aren't random bad luck — they're problems that were already developing before the car left the driveway. A tyre that was 10 PSI low, a coolant level that was creeping toward empty, or a wiper blade that smeared instead of cleared. None of these are invisible; they just go unnoticed when life is busy.

When you add a loaded car, highway speeds, and hours away from home, small issues tend to become expensive ones. Working through this checklist one to three days before you leave gives you time to book a quick mechanic visit if anything turns up. For a deeper look at cost risks worth weighing before you head out, see our vehicle cost and safety readiness checklist.

Tyres

Check tyre pressure on all four tyres (plus the spare) using a gauge, and inflate to the PSI listed on the sticker inside your driver's door jamb — not the number printed on the tyre sidewall. Must
Inspect each tyre's tread depth by placing a quarter into a tread groove — if you can see the top of the head, the tread is low and the tyre should be evaluated by a professional. Must
Look across each tyre's surface for visible cracking, bulges, or uneven wear patterns, which can signal alignment, suspension, or inflation issues. Must
Confirm the spare tyre is present, properly inflated, and that you have a functional jack and lug wrench accessible. Should

Fluids

Check engine oil level with the dipstick on a cold or recently cooled engine — the level should sit between the min and max markers, and the oil should not look gritty or milky. Must
Check coolant (antifreeze) level in the translucent reservoir — it should sit at or near the 'full cold' line; never open the radiator cap on a hot engine. Must
Check brake fluid level in its reservoir under the hood — a noticeably low level can indicate worn brake pads or a leak, both of which warrant professional inspection before a long drive. Must
Top up windshield washer fluid with a solution appropriate for the season, especially if you're driving through areas prone to road spray or insects. Should
Check power steering fluid if your vehicle has a hydraulic system (many newer vehicles use electric power steering and have no reservoir). Nice to have

Lights and Visibility

Walk around the vehicle with a helper or use a reflective surface to confirm all headlights, tail lights, brake lights, and turn signals are functioning. Must
Test your hazard lights, reverse lights, and any fog lights your vehicle is equipped with. Should
Run your wipers and check that blades clear the windshield cleanly without streaking, skipping, or squeaking — replace if they leave smears. Must
Clean all exterior lights and the windshield inside and out; a film of grime significantly reduces visibility, especially at night or in rain. Should

Belts, Battery, and Brakes

Listen for squealing or grinding when braking during a slow test stop — either sound warrants a brake inspection by a qualified mechanic before departure. Must
Check that your battery terminals are free of white or bluish corrosion build-up; if the battery is more than four years old, consider having it load-tested at an auto parts store. Should
Visually inspect the serpentine belt (the large ribbed belt visible near the front of the engine) for cracking, fraying, or glazing — if in doubt, ask a mechanic. Should

Emergency Kit and Documentation

Confirm you have a basic emergency kit in the vehicle: reflective triangles or road flares, jumper cables or a portable jump starter, a basic first-aid kit, and a flashlight with fresh batteries. Must
Pack bottled water and a light snack supply in the car itself (not only in luggage) in case of an unexpected roadside wait. Should
Verify your registration, insurance card, and roadside assistance membership details are in the vehicle and not expired. Must
Download an offline map for your route in case cell coverage is spotty in rural stretches. Nice to have

Tools You'll Want on Hand

Most of this checklist is visual and requires nothing more than your eyes and five minutes of daylight. A few items benefit from basic tools that cost very little and live in most garages already.

Required

Tyre pressure gauge

Measures tyre inflation accurately — guessing by appearance is unreliable, especially on modern low-profile tyres.

Required

Coin or tread depth gauge

Used to quickly assess whether tyre tread depth is adequate for safe highway driving.

Required

Flashlight or work light

Lets you see into the engine bay and under the vehicle clearly, especially in a shaded driveway or garage.

Optional

Portable jump starter

Allows you to restart a dead battery without needing another vehicle — useful on remote stretches of road.

Required

Owner's manual

Contains the correct fluid types, tyre pressure specifications, and service intervals specific to your vehicle.

Loading Up and Heading Out Safely

Once the vehicle itself checks out, how you load it matters. Roof boxes and rear cargo add aerodynamic drag and raise the centre of gravity, which can affect handling — especially noticeable on highway ramps and in strong crosswinds. Distribute heavy items low in the boot and avoid stacking cargo so high it blocks your rear view mirror.

Don't Exceed Your Vehicle's Load Rating

Every vehicle has a Gross Vehicle Weight Rating (GVWR) — the maximum safe total weight including passengers, cargo, and fuel. Exceeding it puts stress on tyres, brakes, and suspension beyond what they were designed to handle. Check your owner's manual or the door jamb sticker for your vehicle's specific limits before packing.

If you're travelling with children, seat installation and child restraint fit deserve their own walkthrough. Our pre-drive safety walkthrough covers car seats, load securing, and emergency kit basics in detail. And if you want to make sure the trip itself runs smoothly once you're rolling, road trips with kids: what actually makes them work is worth a read before you go.
