Are you a taxi driver in the Netherlands with a taxi operator licence? In some municipalities you may use bus or tram lanes. However, in other municipalities you need a separate bus lane dispensation (busbaanontheffing) from the municipal or provincial authority.
Ask your municipal or provincial authority if you need a bus lane dispensation. The application procedure and conditions may differ from one municipality or province to another. In general you will need to provide at least a copy of your driver’s licence and of your taxi driver’s card (taxipas).
Please note: if you want to use bus lanes in Amsterdam, you need a certificate for the joint-use of bus lanes (in Dutch). You can get this certificate by passing the required training and exams (in Dutch) from the Central Office for Motor Vehicle Driver Testing (Centraal Bureau Rijvaardigheidsbewijzen, CBR).
