What does the D-54 'Clean Transport Zone' sign mean?

The D-54 sign marks the beginning of a designated Clean Transport Zone. Its purpose is to reduce pollution by controlling which vehicles can enter based on their emission standards. You generally need a low-emission vehicle, like an electric or hydrogen car, to enter without restrictions.

If your vehicle has high emissions and does not meet the zone's criteria, you might be prohibited from entering altogether. In some cases, you may be allowed entry but will need to pay a fee. Driving into the zone without the necessary permit or failing to pay the fee can result in a fine.

Some zones might offer exemptions, for instance, for local residents or for specific types of vehicles like those used by people with disabilities.
