Half-Term Road Trip Car Checks: What to Sort Before You Set Off

School half-term is almost here and the May bank holidays are stacking up. If you are driving the family down to North Wales, across to the Lakes, or out to the coast for a long weekend, the last thing you want is to be stood on the hard shoulder with the bonnet up. A bit of preparation now saves a ruined trip later, and a thirty-minute check at the garage costs less than a recovery callout from the middle of nowhere.

At Arrow Car Repairs in Wavertree, we get a flood of calls every May from drivers who want their cars looking and running right before a holiday. A pre-trip car service is the most thorough option, but if you are short on time, there are a handful of checks that catch the most common holiday breakdowns. Here is what we look at first.

1. Tyres — pressure, tread and condition

Tyres are the only part of your car actually touching the road. Loaded with luggage, kids and a roof box, your car sits lower and pressures need to be higher than usual. The correct figures are on a sticker inside the driver’s door or in your handbook. Check all four (and the spare) when the tyres are cold for an accurate reading.

The legal minimum tread depth is 1.6mm across the central three-quarters of the tyre, but as the government’s tyre law guidance explains, performance drops well before you hit that limit. We start advising replacement around 3mm because grip in the wet falls off a cliff below that. Look for sidewall bulges, cuts, or anything embedded in the tread. If anything looks dodgy, get it checked before you load the car.

2. Brakes, fluids and a quick under-bonnet look

A long motorway run with a heavy car puts a lot more work through the braking system than your usual school run. If the pedal feels spongy, if there is any squealing or grinding, or if the car pulls to one side when you brake, do not set off until it has been checked. Brake problems rarely fix themselves and they get worse the more you ignore them. Our team handle brake repairs and full mechanical work on all makes and models and can fit you in the same day where possible.

Under the bonnet, top up your screenwash, check the engine oil dipstick, and look at the coolant level in the expansion tank. Coolant should sit between the MIN and MAX marks when the engine is cold — never open the cap on a hot engine. If the level keeps dropping between checks, that is a leak and it needs sorting before any long drive.

3. Battery and starting

A car battery that has been getting away with short runs through spring will often pack in on the first cold morning of a holiday. Slow cranking, dim headlights when the engine is off, or any electrical glitchiness on the dashboard are early warnings. If your battery is more than four years old, it is worth getting it tested. We can check it in a few minutes and supply a replacement battery the same day if needed.

4. Lights, wipers and visibility

Long drives often mean an early start or a late finish, plus the odd downpour. Walk around the car and check every bulb — headlights dipped and main, sidelights, indicators, brake lights and reverse. Get someone to stand behind the car while you press the brake pedal. Replace blown bulbs before you go. Wiper blades that streak or judder need replacing too, and a fresh cabin air filter makes a real difference if you have not changed it in a while.

5. Air-con and cabin comfort

A hot car full of grumpy passengers is no way to start a holiday. If the air-con is not blowing cold, or if there is a damp smell coming through the vents, the system probably needs a re-gas or a clean-out. Our air-conditioning service sorts both. The system loses around 10–15% of its gas a year naturally, so most cars need a re-gas every two to three years even if there is no fault.

6. MOT, service history and warning lights

Before any long trip, check when your MOT runs out. You can look it up free using the government MOT history checker. Driving without a valid MOT invalidates your insurance and lands you with a fine of up to £1,000. If yours is due in the next month or two, get it done before you go.

Any warning light that has been ignored for a few weeks needs looking at before a long journey. A modern car logs fault codes and our diagnostic equipment reads them in minutes. The RAC’s long-journey car check guide makes the same point — small warning signs become roadside breakdowns when you ask the car to do more than its usual short hops.

If you would rather hand the lot over to someone, drop the car in to us in Wavertree before you go. We will check it all, tell you what needs doing, give you a fair price, and have you back on the road in time to load the boot. Free collection and drop-off across Liverpool if you cannot get over to us.

Frequently Asked Questions

How long does a pre-holiday car check take?

A quick visual check covering tyres, lights, fluids and brakes takes around thirty minutes. A full interim service, which goes much deeper, takes around two hours. We will tell you what we have found before doing any work, so there are no surprises on the bill.

Should I check tyre pressures cold or warm?

Always cold. Driving warms the air inside the tyre and pushes the pressure up by a few PSI, which gives you a misleading reading. Check first thing in the morning before you set off, or wait at least three hours after driving.

What pressure should my tyres be at when the car is loaded?

The sticker inside the driver’s door usually shows two figures — one for normal driving and a higher one for a fully loaded car. Use the loaded figure if you have a full boot, roof box, or four or more passengers. If you cannot find the sticker, your owner’s handbook will have it.

My MOT is due during the holiday — can I drive on it?

If your MOT expires before you get back, you are not legally allowed to drive the car (except directly to a pre-booked MOT). Insurance will not cover you either. Get the MOT done before you leave — we run on-site MOT testing and can fit you in same-day where we have a slot.

Do you offer collection and drop-off for a pre-trip check?

Yes — free collection and drop-off across Liverpool and the surrounding areas. If you are flat out at work before the holiday, we will pick the car up, do the checks, and return it the same day where we can.
