Driving Theory, Explained Properly

Warning signs

Triangular, red border

They tell you a hazard is ahead, not what to do about it. Sharp bend, steep descent, narrow road, pedestrian crossing, children, roadworks, falling rocks, level crossing. The correct response to almost all of them is the same: slow down early and be ready to stop.

Regulatory signs

Circular, red border or blue

These carry the force of law. No entry, no overtaking, no parking, speed limits, weight and height restrictions. A circular red-bordered sign is a prohibition; a blue circular sign is a positive instruction, such as a direction you must follow.

Mandatory signs

Blue, circular

Things you must do rather than must not: turn left ahead, keep left, minimum speed, a lane reserved for a particular use. Ignoring one is the same offence as ignoring a prohibition.

Information signs

Rectangular, blue or green

Directions, distances, place names, hospitals, fuel, parking. They do not instruct you, they orient you. Reading them early is what stops the last-second lane change that causes collisions.

Road markings

Painted lines

A solid centre line means do not cross or overtake. A broken line means you may cross when it is safe. Double solid lines apply to both directions. Yellow box junctions must be kept clear. Zebra markings mean pedestrians have priority once they have stepped on.

01

Cockpit drill

Before the engine starts: doors closed, seat positioned so you can fully depress the pedals with a slight bend at the knee, steering reachable with bent elbows, head restraint level with your ears, mirrors adjusted, seatbelt on. Done in the same order every time it takes fifteen seconds.

02

Steering

Hands at roughly nine and three, feeding the wheel rather than crossing your arms. Look where you want to go, not at the bonnet. The car follows your eyes more reliably than most learners expect.

03

Braking

Progressive pressure, then ease off as the car stops so it settles rather than jolts. Brake early and gently instead of late and hard, and leave more distance than feels necessary.

04

Acceleration

Smooth and gradual. Sudden throttle unsettles the car and wastes fuel; in traffic it achieves nothing because you arrive at the same queue.

05

Clutch and gears

In a manual, the clutch is raised to the biting point and held there briefly before the car moves. Change up as the engine note rises, down before you need the power. Do not coast with the clutch depressed.

06

Mirrors

Interior mirror first, then the door mirror on the side you intend to move towards, then signal, then manoeuvre. Every lane change and every turn. Mirrors do not cover the blind spot, so a shoulder check is separate.

07

Indicators

Signal early enough to inform, not so early that it misleads. Cancel the indicator afterwards — a signal left running is worse than none, because other drivers act on it.

Reverse parallel parking

Pull alongside the space, align your rear with the car in front of the gap, reverse until your mirror clears its bumper, then turn towards the kerb. Stop, straighten, and reverse in. Slow enough that you can stop at any point is the whole technique.

Reverse bay parking

Reversing into a bay gives far better control and a much safer exit than driving in forwards. Line up one bay past your target, reverse with your eyes moving between both mirrors and over your shoulder.

Forward bay parking

Easier to enter, harder and more dangerous to leave, because you reverse out into moving traffic with limited view. Use it when the exit is clear.

Hill parking

Facing uphill, turn the wheels away from the kerb and leave it in first gear. Facing downhill, turn the wheels towards the kerb and leave it in reverse. Handbrake on firmly in both cases.

Judging the space

A space needs roughly one and a half times your car length to be comfortable. If you have to ask whether it fits, it probably does not.

Lane changing

Mirror, signal, blind-spot check, then move — in that order, never signal-and-swerve. Change one lane at a time and complete the move before considering the next.

Turning

Approach at a speed that lets you stop, position correctly before you arrive, and do not straddle lanes. Left turns need a check for motorcycles coming up your inside; right turns need a proper gap, not an optimistic one.

U-turns

Only where permitted and where you can see far enough in both directions. Signal, wait for a genuine gap in both directions, and commit in one movement rather than stopping halfway across.

Roundabouts

Give way to traffic already on the roundabout. Approach in the correct lane for your exit, signal your exit as you pass the one before it, and watch for vehicles cutting across lanes.

Overtaking

Only with a clear view of the road ahead, never on a solid centre line, never approaching a bend, crest or junction. If you have to ask whether there is time, there is not.

Following distance

Two seconds behind the vehicle in front on a dry road, considerably more in rain. Count it against a fixed point. Tailgating removes your only reaction margin and gains you nothing.

Blind spots

Every car has areas the mirrors do not cover, and motorcycles fit inside them easily. A quick shoulder check before every lateral move is what mirrors cannot replace.

Hazard awareness

Scan far ahead rather than fixating on the bumper in front. Brake lights three cars up, a pedestrian near a kerb, a door opening on a parked car — all of these are warnings you can act on early.

Emergency braking

Firm, immediate pressure and keep steering. In a car with ABS the pedal will vibrate and the noise is normal; do not release it. Practise it once, with an instructor, somewhere safe, so the first time is not an emergency.

Motorcycles and pedestrians

Both are less visible and far more vulnerable than cars. Assume a motorcycle may be alongside you whenever you move sideways, and that a pedestrian near a kerb may step into the road.

Night driving

Reduce speed, increase following distance, dip your headlights for oncoming traffic, and do not look directly at their lights. Judging distance is harder in the dark than most drivers admit.

Rain and poor visibility

Braking distances lengthen considerably, road markings disappear and standing water pulls at the steering. Slow down, double your following distance, and use lights so you can be seen as well as see.
