The Swedish Heritage Fund has made SEK 2.9 million available to us to develop training and test methods in connection with the dispensation application when the driver has minor visual field loss. At the same time, the Swedish Transport Agency has initiated a review of the regulations for medical requirements regarding visual ability in traffic.
