You do the practice questions on the app. You get them right. Then the real test writes it differently and the answer falls apart.
Four and a half, nine, ten, fifty-six, ninety. All numbers, no picture. They swap places in your head because nobody showed you where each one lives.
You look up 'daily rest' and get a paragraph with three exceptions. Eleven hours, or nine, or three plus nine? The paragraph never says which one is yours.

That's the forty-five minute break. Four and a half hours of driving, then stop. Split it only as fifteen plus thirty. On the clock, not in a paragraph.
Put a number in its place on the clock and it stays put.

From drivers' hours and the tachograph to loads, hazards and full case study drills — the topics behind the theory tests, in the order they make sense.
Each page has one rule, drawn from inside the cab. The reason comes first. The number comes second. You see it where it actually lives — on the dashboard, on the display, on the plate.

That's the orange plate on the back of a tanker. Hazard identification number on top, UN substance number below. One page, one drawing, one thing to know.
Read the reason, see the plate, and the number has somewhere to live.
How each part of the test is scored, from Part 1a multiple choice to the Part 2 case studies, and how to use this book.
Every drivers' hours limit drawn on the dashboard clock: daily driving, breaks, weekly rest. Then working time, night work and the tachograph display — symbol by symbol.
Licence categories, gross and train weights, heights, speed limits, air brakes and the walk-round check. Then load security, coupling, dangerous goods and passenger safety.
Blind spots, stopping distances, turning long, weather driving and hazard perception from the higher cab. Incidents, breakdowns, fire, fitness to drive and the Driver CPC requirement.
Full Part 2 case study drills step by step, the numbers that look alike and a night-before revision checklist.

Test yourself with questions written from scratch, worded differently on purpose, so you practise understanding rather than recognising.

Keep apart the numbers that blur together (hours, breaks, rest, weights) and avoid the most frequent mix-ups, on quick cards to print.
📄 Digital book in PDF: it comes by email. Nothing is shipped on paper.
PDF by email: You receive Lorry & Bus Theory From the Cab as a PDF in your inbox, along with the 2 free books. You pay once: no installments, no extra charges.
You drive a van or a 7.5-tonner and you need to pass the Cat C theory before you can book the practical. Already hold Cat C and going for C+E? There's no new theory test, but the book works as a full refresher on hours, loads and coupling.
You want to drive a minibus, bus or coach. The book covers both lorry and bus topics, and differences are flagged on the page.
You have been behind the wheel for decades but never sat a multiple-choice theory test. The format has changed and you want to understand it, not just memorise it.

30-day 100% money-back guarantee. Use the book in your real study sessions. If it didn't help you understand the rules, tell us what didn't work and we'll refund every penny.
No. It is a PDF you receive by email. You can read it on your phone, tablet or computer, and print it if you want a paper copy for the cab.
Yes. Every page is designed for a phone screen. Open it on a break or at home the night before the test.
It works both ways. Each topic starts with the reason, so you don't need previous theory knowledge. If you've been driving for years, you'll recognise every scene — the book just puts the numbers and rules you've never had to sit a test on in the right order, on the clock and on the display.
By email, in PDF. You get the book and the two bonus books at the email address you enter at checkout.
No. Independent study guide. Not affiliated with, authorised or endorsed by DVSA or any government body. All practice questions are written from scratch for this book. Does not replace formal training.
Yes. The book covers the theory topics for categories C1, C, C+E, D1 and D. Where a rule differs, it is flagged on the page.
Yes. Drivers' hours, the tachograph and the theory tests are the same across England, Scotland and Wales. Where a rule differs — for example the lower drink-drive limit in Scotland — it is flagged on the same page. Northern Ireland is not covered.
The app tests whether you recognise a sentence, and the official book gives you the full text. This book sits between them: one topic per page, drawn from the cab, with the reason first. So when the question is worded differently, you can still work out the answer. Use it alongside the app and the official material, not instead of them.
Yes. You pay once and the PDF is yours to keep. No subscription, no renewal.
No. This is study material for the theory tests. It does not give you a certificate, a Driver CPC qualification card or periodic training hours. You still sit the official DVSA tests, and it does not replace professional training, an approved training provider or supervised on-road practice.
The theory test does not have to be a memory contest.
When every rule has a reason and every number has a place on the clock, the answer comes to you — even when the question is worded differently.
Open the book, see the page, understand the rule.
You already know how to drive. Now see the theory the way it should have been taught.
