EDT Lessons 1 to 4: Getting the Car Under Control
The first four EDT lessons have no roundabouts, no dual carriageways, barely any traffic. Just you and a machine you don't trust yet. That's the point. You can't share a road you can't yet steer.

These are lessons one through four of the twelve, and they run in that order for a reason. Skip ahead and you build a house on a floor that isn't set. Here's what each of the four is actually for.
Lesson 1: Car Controls and Safety Checks
The cockpit drill. Seat, mirrors, steering, pedals, the lot, before the engine's even running. It sounds like box-ticking and it is, right up until the day you drive a car that isn't yours and your hand finds everything without your eyes leaving the road. That's what this hour is buying you. You also learn the safety checks, the walk-round stuff, the tyres and lights and fluids nobody does until the one morning it matters.
Mirrors before you move. Every time. Not because the lesson says so, but because in six months you want your neck turning to the blind spot on its own, without a thought. Habits set in lesson one are the ones that hold under pressure.
Lesson 2: Correct Positioning
Where the car actually belongs on the road. Not hugging the kerb like you're afraid of it, not drifting toward the centre line like you own it. A proper road position, and a following distance that gives you room to think. The two-second rule everyone knows and nobody keeps lives here. Learn it now, because the tester can see the gap you're not leaving.
Lesson 3: Changing Direction
Turning. Left and right, into and out of junctions, with the Mirror, Signal, Manoeuvre routine that has to become one movement, not three separate thoughts. The signal is part of that movement and it has to be honest. A signal you flick on out of habit while you're already turning is worse than no signal, because it lies to the car behind you about what you're doing.
Lesson 4: Progression Management
Fancy name for a simple idea. Making smooth, sensible progress. Moving off, changing up and down through the gears at the right time, using the accelerator and brake like you mean them, stopping the car exactly where you chose to and not a foot past. It's the hour where the jerky stops being jerky. The kangaroo start goes to die here, or it should.
Why this block is the one people undervalue
Learners want to get to the roundabouts, because the roundabouts feel like real driving. But I've watched more tests lost to a sloppy foundation than to any roundabout. The person who never nailed clutch control in lesson four is the same person who stalls at the lights on test day with a bus behind them, and the stall was never the problem. It was the block they rushed to get past.
Get these four right and the rest of the twelve have something to stand on. For where lessons one to four sit in the whole programme, here's the 12 EDT lessons explained end to end. Rush this block and you'll pay for it around lesson six, at a roundabout, in front of someone whose job is to notice.
