SERU Test Secrets Revealed: How to Use the 2026 Open-Book Rule to Pass First Time

If you are looking to become a private hire driver in London, you’ve likely heard the term "SERU" mentioned more than a few times. The Safety, Equality, and Regulatory Understanding (SERU) assessment is a mandatory requirement from Transport for London (TfL), designed to ensure every driver understands their responsibilities and the law.

For many, the SERU test has been a source of significant anxiety. However, there is a game-changer for 2026: The SERU test is now an open-book exam.

This doesn't mean it’s an automatic pass: far from it. In fact, many drivers still fail because they don't know how to navigate the handbook under pressure. At PCO GO, we’ve seen exactly what works and what doesn't. In this guide, I’m going to reveal the secrets of the 2026 open-book rule and show you exactly how to use it to secure your license on the first try.

What Exactly Is the 2026 "Open-Book" Rule?

In 2026, TfL transitioned the SERU assessment to an open-book format. This means that when you sit down at the computer for your exam, you will be provided with a physical copy of the PHV Driver Handbook.

Key Facts About the Open-Book Format:

• The Handbook is Provided: You do not need to (and are not allowed to) bring your own copy. One will be waiting for you at the test centre.
• Reference Questions: Many questions now specifically mention a section number, page number, or heading, directing you exactly where to look.
• Increased Time: To account for the time spent looking up information, the test duration has been increased to 60 minutes (up from 45 minutes).
• Total Questions: You will still face 36 questions, and you need a score of at least 60% (23 correct answers) to pass.

While having the "answers" in front of you sounds easy, the real challenge is speed. You have roughly 1.5 minutes per question. If you spend 5 minutes searching for one answer, you’ll run out of time for the rest.

The Secret Structure: What’s Inside the Test?

The SERU test isn't just a basic multiple-choice quiz. It’s designed to test your reading and writing skills as much as your knowledge of the rules.

1. Multiple-Choice Questions (MCQs)

These are standard "pick the right answer" questions. With the open-book rule, these are your "easy wins." If a question asks about the rules for assistance dogs, you can quickly flip to the "Equality and Accessibility" section of the handbook to confirm the exact wording.

2. Fill-in-the-Blanks

This is where most candidates struggle. You will be given a sentence with missing words, and you must type the correct words in the boxes. Insider Tip: TfL takes these sentences directly from the handbook. The "secret" here is to find the exact sentence in the book and copy the spelling and grammar perfectly. Even a small spelling mistake can cost you the mark.

How to Navigate the Handbook Like a Pro

To pass first time, you need to treat the PHV Driver Handbook like a map. You don’t need to memorize every word, but you must know where every "landmark" is.

Know Your Sections

The handbook is divided into several key areas. You should be able to flip to these sections almost instantly:

• Section 1: Driver Requirements (Licensing, insurance, and medicals).
• Section 2: Professional Conduct (Customer service and disputes).
• Section 3: Equality and Accessibility (The Equality Act, wheelchairs, and assistance dogs).
• Section 4: Safety and Safeguarding (Recognising signs of exploitation and reporting crimes).
• Section 5: Enforcement (What happens if you break the rules).

Use Keywords

When you read a question, identify the keyword. If the question mentions "unattended bags," scan the headings in the handbook for "Safety" or "Security." Don't read every sentence: scan the bold headings first.

Common Pitfalls (And How to Avoid Them)

Even with the book open, many drivers fall into these three traps:

1. Over-Reliance on the Book: If you try to look up every single answer, you will run out of time. Use your preparation to learn the basics so you only need the book for the tricky, specific details.
2. Poor Time Management: If a question is taking too long, skip it. You can come back to it at the end. Get the easy marks first.
3. Ignoring Grammar: In the fill-in-the-blanks section, the test checks if you understand the English language. Ensure you are using the correct "tense" (e.g., "reporting" vs "reported") as found in the handbook.

Why Training with PCO GO Makes the Difference

When you train with us in London, you get:

• Real Exam Mocks: Practice with the same question formats (MCQ and fill-in-the-blanks) you’ll see on the day.

• Confidence Building: We hold your hand through the whole process, from your PCO license application to the final test.

Your 2-Week SERU Study Plan

If your test is coming up, follow this simple plan to ensure success:

1. Days 1-3: Read the PHV Driver Handbook from cover to cover once. Don't try to memorize it: just understand the layout.
2. Days 4-7: Take practice quizzes online. Focus on identifying which section of the handbook each question relates to.
3. Days 8-10: Focus exclusively on fill-in-the-blank exercises. This is the "pass or fail" zone for most drivers.
4. Days 11-14: Sit at least three full-length, 60-minute mock exams using a physical copy of the handbook to practice your navigation speed.

Frequent Flyer Tip: The "Rule of Three"

When using the open-book method for a fill-in-the-blank question, always read the sentence before and the sentence after the one you found in the handbook. This ensures you have the correct context and haven't accidentally pulled a word from a different regulation.

Frequently Asked Questions (FAQ)

Can I bring my own highlighted handbook to the SERU test?

No. TfL provides a clean, standard copy of the PHV Driver Handbook at the test centre. You cannot bring any notes, pens, or your own copy into the exam room.

What is the pass mark for the SERU test in 2026?

The pass mark is 60%. Out of the 36 questions, you need to answer at least 23 correctly.

Is the SERU test difficult if English is my second language?

The test does assess your understanding of English. However, because it is now open-book, you have the advantage of seeing the correct spelling and grammar in the handbook. Training with PCO GO's specialized software is highly recommended for non-native speakers.

How long does it take to get my SERU results?

Typically, TfL will notify you of your results via email within a few weeks of completing the assessment, though this can vary based on their current backlog.
