How to Prepare Your Car for a Long Road Trip

Why pre-trip preparation matters

A long road trip puts extra strain on your vehicle — sustained highway speeds, heavier loads, and long hours in varying weather. A few simple checks before you leave can prevent the most common causes of breakdowns and keep you safe, comfortable, and on schedule.

This checklist takes most drivers 30–45 minutes. If your car is already well maintained, you will likely just confirm everything is fine. If a service is overdue, a trip is the right time to take care of it.

One to two weeks before the trip

Give yourself time to fix anything you find:

• Book a service if a regular service is nearly due. It is far better to service before a trip than to risk a problem on the road.
• Check warning lights. Any light that is on should be diagnosed before you leave. See our guide to Understanding Common Dashboard Warning Lights.
• Inspect tyres for cuts, bulges, or uneven wear. Replace tyres that are damaged or badly worn — a long trip is not the time to push their limits.

Fluid checks

Check these with the car parked on level ground and the engine cold or cool:

• Engine oil — pull the dipstick, wipe, reinsert, and read. Top up if low. If the oil is very dark or gritty and a change is due, do it before the trip. See our Engine Oil Guide.
• Coolant — check the reservoir level. The coolant keeps your engine from overheating on long drives in hot weather. Never open the radiator cap when the engine is hot.
• Brake fluid — should sit between MIN and MAX. A low level or a sudden drop may indicate a leak or worn brake pads.
• Windscreen washer fluid — top it up. A dirty windscreen with no washer fluid is dangerous on a long drive, especially in rain or after driving through dust.
• Power steering fluid (if your car uses hydraulic steering) — check and top up if needed.

Tyres

Your tyres are critical for safety, comfort, and fuel economy on a long trip:

• Pressure — check all four tyres plus the spare when cold. Use the pressure recommended on your car's placard (usually on the driver's door jamb), not the maximum printed on the tyre. See our Tyre Pressure Guide.
• Tread depth — the legal minimum varies by country, but 3 mm or more is recommended for safe wet-road grip. Replace tyres that are close to the limit.
• Spare tyre — confirm it is present, inflated, and in usable condition. Know how to change a wheel, or ensure you have roadside assistance.
• Wheel alignment — if the car pulls to one side or the steering vibrates, have the alignment checked before a long drive.

Brakes

• Brake pedal feel — the pedal should be firm. A soft or spongy pedal needs attention before a long trip.
• Brake noise — squealing or grinding when braking is a sign the pads may be worn. Have them inspected.
• Handbrake — test it holds the car on a slope.

Lights and electrics

• All lights — headlights (low and high beam), indicators, brake lights, reversing lights, and fog lights. Have someone help you check, or park against a wall.
• Wipers — replace blades if they streak or smear. Good visibility is essential on a long drive.
• Horn — test it works.
• Battery — if your battery is more than three years old or has been slow to start, have it tested. A weak battery can fail at the worst time.

Emergency essentials to carry

Pack these in the boot:

• Spare wheel, jack, and wheel brace (or a tyre repair kit).
• Jumper cables and a basic tool kit.
• First-aid kit.
• Reflective warning triangle and a high-visibility vest.
• Torch with spare batteries.
• Water and snacks for you and any passengers.
• Spare engine oil and coolant matching your car's specifications.
• Phone charger and a printed copy of your route and emergency contacts.

During the trip

• Take breaks every two hours or 200 km to reduce fatigue.
• Monitor the dashboard for any new warning lights.
• Check tyre pressure if you have driven on rough roads or hit a pothole.
• Refuel before you are nearly empty, especially in remote areas where fuel stations are far apart.

FAQ

How far in advance should I check my car before a road trip? One to two weeks is ideal. It gives you time to fix anything without rushing.

Do I need a full service before every long trip? No. Only if a regular service is already due or something feels wrong. Otherwise, a thorough check of fluids, tyres, brakes, and lights is enough.

What is the most common cause of breakdowns on long trips? Tyre problems and overheating are among the most common. Both are largely preventable with a pre-trip check.
