About the SERU TfL Mock Test
~7 min read · Updated April 2026
The TfL SERU assessment is mandatory for every new London private hire driver since October 2021. It covers safety, equality and regulatory understanding and is based on the Private Hire Driver's Handbook. TfL does not publish a fixed percentage pass mark — they judge whether you give the safest, most legally correct response. You must pass it before TfL will issue your PHV licence.
Each of our mocks is a 24-question SERU practice mock with multiple-choice and missing-word style questions. We set a practice target of 75% — that extra margin builds the confidence you need for the real assessment. Roughly 40% of candidates fail their first attempt, almost always on the safeguarding and equality sections.
Use the mocks to drill the syllabus areas TfL focus on, then read the official PHV Driver's Handbook alongside them.
Format and what to expect
SERU is sat at a TfL-approved centre and includes multiple-choice and missing-word / sentence-completion questions drawn from the PHV Driver's Handbook. TfL does not publish a fixed percentage pass mark — the focus is on giving the safest, most legally correct response to each scenario.
Questions are scenario-based: 'A passenger asks you to do X — what do you do?' The right answer is almost always the safest, most legally compliant and most respectful option. Common-sense alone is not enough — you need to know the specific TfL rules from the PHV Driver's Handbook.
On UK Test Hub each mock is a 24-question SERU practice mock with a practice target of 75%. The practice target is set higher than typical pass thresholds on purpose, to give you a safety margin on the day.
What SERU covers
TfL bases SERU on the PHV Driver's Handbook and groups the content into five core areas: (1) Safety — safeguarding, passenger safety, vehicle safety and roadworthiness. (2) Equality — protected characteristics, reasonable adjustments and the Equality Act 2010. (3) Regulatory understanding — TfL licensing conditions, notification duties, insurance and MOT for hire and reward. (4) Passenger protection — assistance dogs, wheelchair accessibility, vulnerable passengers and how to report concerns. (5) Driver conduct — professional behaviour, lost property, fares and routes.
Safeguarding and equality usually carry the most weight. Drill these areas hardest.
Safeguarding — the make-or-break section
Know the categories of abuse (physical, sexual, emotional, neglect, financial, modern slavery, child sexual exploitation, domestic abuse). Know the four Rs: Recognise, Respond, Report, Record.
If you suspect a child or vulnerable adult is at immediate risk, call 999. For non-immediate concerns, report to the local council safeguarding team and notify TfL. Never investigate yourself, never confront the suspected abuser, never promise confidentiality to the victim.
Equality and assistance dogs
You must accept assistance dogs at no extra charge. Refusal is a criminal offence under the Equality Act 2010 unless you have a TfL-issued medical exemption certificate (and the certificate must be displayed in your vehicle).
You must accept passengers in wheelchairs at no extra charge if your vehicle is wheelchair accessible. You may not charge extra for assistance, loading time, or for guide-dog passengers.
How to study
Read the official TfL Private Hire Driver's Handbook (free PDF on tfl.gov.uk) cover to cover. Then drill the SERU mocks on UK Test Hub for two to three weeks. After every wrong answer, find the rule in the handbook.
Most failed candidates skip the handbook and go straight to mocks. Don't — the handbook contains specific phrases TfL test on.
Booking and on the day
Book through your TfL applicant portal. Bring photo ID (passport or driving licence). Arrive 15 minutes early. No phones, no notes, no bags in the test room.
Result is on screen at the end. Pass certificates go straight to TfL automatically — you don't need to send anything in.
