Why a Pre-Trip Check Matters

Most vehicle breakdowns and a significant share of road incidents involve factors that a driver could have caught before leaving home — an underinflated tyre, a burnt-out brake light, or low coolant. Taking 10 to 20 minutes to run through a structured inspection is one of the simplest, lowest-cost habits any driver can build.

This checklist applies to everyday journeys as well as longer road trips. For longer drives across changing conditions, pair it with our seasonal maintenance guide to account for temperature extremes and weather-related wear. If you're new to vehicle ownership, our car maintenance guide for new drivers explains the underlying systems in more detail.

The checks below are grouped by area of the vehicle so you can move efficiently from one zone to the next without backtracking.

Required

Tyre pressure gauge

Accurately measures tyre inflation so you can adjust to the manufacturer's recommended PSI.

Required

Tread-depth gauge

Gives a precise measurement of remaining tyre tread to verify you meet the legal minimum.

Required

Vehicle owner's manual

Provides the correct fluid grades, tyre pressures, and warning-light definitions specific to your vehicle.

Optional

Microfibre cloth

Cleans mirrors and glass quickly to ensure full visibility before departure.

Optional

Torch or phone flashlight

Helps you inspect tyre sidewalls and under-hood components in low-light conditions.

How to Use This Checklist

Work through each group in sequence — exterior first, then interior, then under the hood. Items marked must are non-negotiable safety checks; should items are strongly recommended; nice to have items add an extra layer of confidence for longer journeys.

If your dashboard shows any warning symbols when you start the vehicle, look them up before proceeding. Our guide to dashboard warning lights explains what each symbol means and how urgently it needs attention. Never dismiss an illuminated warning light by assuming it will resolve itself en route.

Brake Fluid Low? Don't Drive Yet

A brake fluid level that has dropped suddenly — rather than declining gradually with brake pad wear — can signal a hydraulic leak in the braking system. This is a serious safety issue. If you are unsure why the level is low, do not drive the vehicle until a qualified mechanic has inspected the brake system.

Tyres

Check all four tyre pressures using a gauge and inflate to the vehicle manufacturer's recommended PSI (found on the door jamb sticker or owner's manual). Must
Inspect each tyre visually for cuts, bulges, embedded objects, or uneven tread wear that could indicate an alignment or suspension problem. Must
Verify tread depth is above the legal minimum of 2/32 inch using a tread-depth gauge or the penny test. Must
Confirm the spare tyre is present, correctly inflated, and that the jack and wheel brace are accessible. Should

Lights and Signals

Test headlights on both low and high beam, then switch them off and verify daytime running lights activate if fitted. Must
Check all turn signals front and rear, as well as hazard flashers, for correct operation and flash rate. Must
Confirm brake lights are working — press the pedal while someone stands behind the vehicle, or use a wall reflection. Must
Inspect reverse lights and rear fog lights if equipped. Should

Fluid Levels

Check engine oil level with the dipstick when the engine is cold; top up if below the minimum mark using the grade specified in your owner's manual. Must
Verify coolant (antifreeze) level in the overflow reservoir is between the MIN and MAX marks. Must
Inspect windshield washer fluid and fill the reservoir completely — especially important before highway driving. Should
Check brake fluid level in the reservoir; a notably low level can indicate worn brake pads or a leak and warrants professional inspection. Must
Glance at power steering fluid if your vehicle has a hydraulic system (not applicable to electric power steering). Nice to have

Mirrors and Visibility

Adjust the driver's side mirror to minimise the blind spot on the left rear quarter of the vehicle. Must
Set the passenger mirror so the horizon bisects the mirror and the side of your car is just visible. Must
Position the interior rear-view mirror so the full rear window is framed without needing to move your head. Must
Clean all exterior mirrors and windows — front, rear, and side — of dirt, condensation, or frost before departing. Must

Wipers and Safety Equipment

Run the windshield wipers and confirm they clear the glass cleanly without streaking or skipping. Must
Verify seat belts for all occupied seats latch securely and retract smoothly. Must
Confirm a basic emergency kit is in the vehicle: reflective triangle or road flares, first-aid kit, and a torch. Should

After the Check: Before You Pull Away

Once you've completed the physical inspection, take 60 seconds inside the cabin. Adjust your seat and steering wheel so you have full pedal travel and an unobstructed view. Set mirrors so you can see both rear quarters without moving your head significantly. Confirm your phone is mounted or stored — not in your hand — and that your route is loaded if you're using navigation.

For road trips that extend beyond your usual area, the broader pre-trip checklist covers documents, reservations, and other logistics you'll want to handle before departure. Keeping both checklists together means nothing slips through the cracks.

Don't Rely on Warning Lights Alone

Dashboard sensors are a helpful safety net, but they don't catch everything. Tyre pressure monitors, for example, typically only alert you once pressure has dropped significantly — by which point handling can already be compromised. A visual and gauge-based inspection is always more reliable than waiting for a light to appear.
