Can you use an already issued route permit for different vehicles of the same type?

When applying for the authorisation, different port markings can be added for which the same route authorisation can be reused in the case of port vehicles of the same category, in the same composition and with the same maximum dimensions, mass and axle loads.

It is also possible to retroactively add port vehicles of the same category, in the same composition and with the same maximum dimensions, mass and axle loads to a route permit already issued.
