You are driving a vehicle which does not perform payable transport of passengers on regular lines. Are you allowed in this situation to change into the right lane?

Why?

In the video, the BUS sign identifies the right-hand lane used by the bus as reserved for authorised regular passenger services. The vehicle described in the question may not enter that lane. The broken lane marking does not remove this restriction.
