TfL Private Hire Vehicle Driver’s Handbook https://content.tfl.gov.uk/phv-driver-handbook-v1.pdf In order to prepare for the SERU test you need to check the private hire handbook. Please study it carefully as you will get questions from it at the TfL testing centre.
ADCU mock tests https://linktr.ee/adcuseru The union also gives our members a couple of mock tests that you can practice at home, after you finish reading the handbook above. These samples are the same as the ones presented at our weekly SERU trainings in case you were not able to book your place.
