Legend:

• TDVL = Taxi Driver's Vocational Licence
• PDVL = Private Hire Car Driver's Vocational Licence
• BAVL = Bus Attendant's Vocational Licence 
• BDVL = Bus Driver's Vocational Licence
• ODVL = Omnibus Driver’s Vocational Licence

Question: 

Is it possible for an individual to hold TDVL, PDVL, BAVL, BDVL and ODVL?

Answer:

1. Bus Attendant, Bus Driver and Omnibus Driver Vocational Licence (BAVL, BDVL and ODVL) are independent Vocational Licence. An individual can only either hold 1 or all 3 of the licences.
2. Taxi Driver and Private Hire Car Driver Vocational Licences (TDVL and PDVL) are mutually exclusive. An individual can only hold 1 of these licences.

Thus, an individual can only hold up to a maximum total of 4 of the above vocational licences.
