Hydrogen trucks in Poland will recieve green number plates. Since January 1st 2020, all new registered fuel cell vehicles in Poland will be signed by green number plates with a yellow frame. This is a new mechanism for indicating zero-emission cars, which may i.a. use bus lanes in cities.
Special license plates for cars with fuel cells are implemented from January 1st 2020. Green plates for hydrogen cars from the previous ones differ in the background (green instead of white) and have an additional yellow frame. For electric vehicles the frame is in black colour. Other elements of 'ecological’ tables remains unchanged, i.e. arrangement and allocation of letters, EU flag and hologram.
