The Cockpit Drill on Your Driving Test in 2026: Seat, Mirrors and Seatbelt Checks Explained

Every driving test begins with something so small that most learners forget it exists: the moment you sit down in the driver’s seat and set the car up around you. Instructors call it the cockpit drill – the sequence of checks that gets your doors, seat, steering, seatbelt and mirrors right before you touch the ignition. It takes twenty seconds. Done badly, it quietly generates faults for the next forty minutes.

This matters more than it looks. A seat set too far back means you cannot fully depress the clutch on a hill start. A mirror angled wrongly means you genuinely cannot see the vehicle the examiner expects you to have seen. A head restraint left low is a safety issue an examiner will notice. In 2026 the cockpit drill is not marked as its own box on the DL25 marking sheet, but the consequences of getting it wrong show up in the boxes that are marked: control, observation, use of mirrors and moving off safely.

What Is the Cockpit Drill?

The cockpit drill is the routine you carry out every time you get into a car, especially one you have not driven before. Most instructors teach it as DSSSM:

• D – Doors. All doors closed properly, and the boot shut.
• S – Seat. Position, height, backrest angle and head restraint.
• S – Steering. Wheel position adjusted if the car allows it.
• S – Seatbelt. Yours on and correctly positioned, and everyone else’s too.
• M – Mirrors. Interior mirror first, then both door mirrors.

Some instructors use POM, others use a slightly different order. The letters matter far less than the habit. What the examiner cares about is that you are set up so you can control the car and see what is happening around it.

Doors: The Check Everyone Skips

Before you do anything else, glance at the door warning light or check that each door is properly latched. A door that pops open at a junction is a genuinely dangerous situation and will end a test immediately. If you are taking your test in your own car, check the boot too – a boot that has not clicked shut will flap open at the first speed bump.

Seat: The Single Biggest Cause of Control Faults

Getting the seat wrong is responsible for more control faults than most learners realise. Here is how to set it properly.

Distance from the pedals

Push the clutch pedal (or the brake in an automatic) all the way to the floor. Your leg should still have a slight bend at the knee. If your leg locks straight, you are too far back and you will struggle to find the biting point smoothly on a hill. If your knee is jammed up near the steering wheel, you are too close and you lose fine control.

Backrest angle

Sit upright rather than reclined. Hold the top of the steering wheel with one hand: your shoulder should stay in contact with the seat. If it lifts off, the backrest is too far back. A reclined seat feels relaxed and makes it much harder to steer accurately through a manoeuvre.

Seat height

Raise the seat until you have a clear view over the bonnet and can see the road close in front of the car. Shorter drivers in particular benefit from going higher than feels natural. Being able to judge where the front of the car is makes bay parking and pulling up at the kerb dramatically easier.

The head restraint

This is a safety item, not a headrest. The middle of the restraint should be roughly level with the top of your ears, and as close to the back of your head as comfort allows. Examiners do notice a head restraint left at the bottom of its travel.

Steering: A Small Adjustment That Matters

If the car has an adjustable steering column, set it so that you can see the full instrument cluster and so your arms are comfortably bent when your hands are at the ten-to-two or quarter-to-three position. Your wrists should be able to rest on the top of the wheel with your shoulders still against the seat. Make sure the column is locked before you drive – a wheel that drops while you are moving is alarming and unsafe.

Seatbelt: Yours and Everyone Else’s

Put your seatbelt on and check it lies flat across your shoulder and low across your hips, not across your neck or your stomach. If the car has an adjustable belt anchor, set it to suit your height.

Legally, you are responsible for making sure passengers under 14 are properly restrained, and the examiner expects you to be aware of who is in the car. On test that is straightforward – the examiner will belt themselves in – but the habit matters for the rest of your driving life.

Mirrors: Set Them Once, Set Them Right

The interior mirror

Adjust it so you frame the entire rear window with as little sky and headlining as possible. Move it with your fingertips on the edge rather than grabbing the glass, which leaves smears exactly where you need to see. If it has a dipping tab, know how to use it before you find yourself dazzled at night.

The door mirrors

This is where most learners go wrong. Set each door mirror so that you can just see a sliver of the side of your own car along the inside edge – roughly a quarter of the mirror – with the rest showing the road and lane beside you. Horizontally, the horizon should sit around the middle of the glass. Mirrors angled too far inwards duplicate what the interior mirror already shows you and widen your blind spot.

What Happens on Test Day

You will not usually be watched performing a full cockpit drill on the driving test, because the car is already set up from your warm-up drive. What the examiner sees is the result: whether you can operate the controls smoothly, whether your observations are effective, and whether you look comfortable. The drill matters most in two situations:

1. If you are using an unfamiliar car – for example a family car for private practice, or a hire car for the test. Set it up properly before you move.
2. If anything changes during the test – if you realise mid-test that a mirror has been knocked, pull up somewhere safe and legal, correct it, and move off again. That is far better than driving on unable to see.

Examiners have no problem at all with a candidate who says ‘I’d like to pull over and adjust my mirror’. They have a very big problem with a candidate who changes lanes without being able to see.

A Quick Pre-Drive Checklist

• Doors and boot closed, warning light off.
• Seat far enough forward for full clutch travel with a slight knee bend.
• Backrest upright; shoulder stays on the seat when reaching the top of the wheel.
• Seat height giving a clear view over the bonnet.
• Head restraint level with the top of your ears.
• Steering column adjusted and locked.
• Seatbelt on, flat, and correctly positioned.
• Interior mirror framing the rear window.
• Door mirrors showing a sliver of your own car and plenty of road.
• Handbrake on, gear in neutral, before you start the engine.

Practise It Until It Is Automatic

The cockpit drill is one of the easiest parts of learning to drive to get right, because it does not depend on traffic, weather, or nerve. It only depends on repetition. Do it every single time you get in a car during private practice and it will be automatic by test day – which frees up all of your attention for the part that actually is difficult: reading the road.

Speaking of which, the roads themselves are the other half of the equation. Knowing your test centre’s routes before you drive them removes an enormous amount of pressure on the day.
