Answers

  1. B. 21 or older. You must be aged 21 or older when you apply for a London PHV driver's licence.
  2. D. no upper age limit. TfL sets no upper age limit. An older driver can hold a licence if they still meet the other requirements.
  3. A. three years. TfL needs a full DVLA, Northern Ireland or other EEA licence that is at least three years old.
  4. C. Only the 18 months on his UK licence. TfL's current page says time on a licence from a designated country before the exchange does not count. Only time on the UK or EU/EEA licence counts. The Handbook does not explain this.
  5. B. an enhanced check. You must have an enhanced criminal records check from the DBS. TfL uses a separate company to arrange it, and you must use that company.
  6. D. Register before you get a licence and stay subscribed. The Handbook does not mention this, but TfL's current page does. TfL cannot grant a licence until you have registered, and once licensed you must keep your subscription going without a break.
  7. A. the SERU assessment. The SERU assessment also tells TfL about your reading and writing. A separate test covers speaking and listening.
  8. B. A Certificate of Good Conduct from that country. The Handbook does not cover this, but TfL's current page does. You need a Certificate of Good Conduct if you lived abroad for three months or more in a row in the last 10 years. Long holidays count too.
  9. D. three years. A licence normally lasts for three years. If TfL gives you a shorter one, the letter with the licence explains why.
  10. A. seven days. The Handbook says to show it straight away or within seven days at most, and the same applies to a TfL Authorised Officer. The PHV Act 1998 and TfL's Driver Policy say six days, so produce it within six to be safe.
  11. B. Keep it and follow the conditions. Keep the letter and follow any conditions in it. If you do not follow them, TfL may revoke your licence.
  12. C. Yes, and people must be able to see it. You must wear your badge whenever you are working, and this includes waiting for a booking. People must be able to see it clearly.
  13. D. Let them see your badge. Your licence number is on your badge. Let the passenger see it so they can write the number down.
  14. B. Braille. The badge includes Braille text, so a vision-impaired person can tell that you are licensed.
  15. C. Wearing it presents a specific risk. TfL's Driver Policy says it gives exemptions only in exceptional circumstances, where wearing a badge presents a specific risk. The Handbook only says that TfL can give an exemption.
  16. A. a crime reference number. Report it to TfL straight away. Also report a stolen badge to the police and get a crime reference number. You cannot work without your badge.
  17. C. DVLA Group 2. The medical standards for London PHV drivers are the DVLA Group 2 standards.
  18. B. 45. From the age of 45, a PHV driver must have a medical examination at each renewal.
  19. D. every year. From the age of 65, a PHV driver must have a medical assessment every year. Missing information could cost you your licence.
  20. A. Someone with a DVLA Group 2 licence. TfL's current page lists a full or provisional DVLA Group 2 licence. The Handbook also lists a London taxi licence and a pilot's licence, but the current page does not, so ask TfL if you hold one.
  21. C. You. You are responsible. A doctor must fill in all the health information, and you must return the form to TfL.
  22. A. Immediately. Tell TfL immediately, even if your next medical is not due yet. Do not wait for your next renewal.
  23. C. Epilepsy. Epilepsy is on TfL's list of conditions to report. Others include diabetes, heart conditions, high blood pressure and strokes.
  24. A. Contact TfL for advice. If you are not sure, contact TfL for advice. TfL also suggests you check with the DVLA, because its standards often change.
  25. C. Within 48 hours. The Handbook says 'immediately'. TfL's current page sets a limit: if your licence was granted on or after 1 July 2024, report any arrest and release, charge, caution or conviction within 48 hours.
  26. C. 21 days. The Handbook says 'immediately', but TfL's current page sets different limits. For a licence granted before 1 July 2024, report new convictions and cautions within 21 days. TfL strongly encourages 48 hours, and the 48-hour rule applies once you are relicensed.
  27. A. the police. It is your own job to tell TfL. The Handbook warns you not to rely on the police doing it, and failing to report a conviction could cost you your licence.
  28. B. A road offence with penalty points. You must report offences that put penalty points on your driving licence. You do not need to report PCNs or parking tickets that bring no points.
  29. A. take licensing action. You do not have to report tickets with no points. But TfL expects responsible behaviour, so it may act if it learns you get them often.
  30. D. 21 days. Tell TfL about a new home address within 21 days. Also tell TfL about a new email address or phone number.
  31. C. The DVLA. The law says you must tell the DVLA. The address on your PHV driver's licence should match the one on your DVLA licence.
  32. A. Tell TfL immediately. A suspended, revoked or refused licence with another authority is a change you must tell TfL about straight away.
  33. B. TfL can only decide on what it has been told. TfL can only make licensing decisions on the information it receives. Your reply gives TfL your side.
  34. B. seven days. Return your licence within seven days. If you do not, or the decision takes effect at once, TfL may send an Authorised Officer to collect it.
