As a user of an older car with a retractable awning, I would like to renew my half-yearly vignette. Buying an annual one and refunding the difference when the vehicle is checked out would also be an acceptable option. I drive a cabrio from April to the end of October. I register and deregister my vehicle every year. How to solve the problem of driving e.g. on the Ljubljana ring road without penalising dars. I suggest either introducing a half-yearly vignette or paying for a full year with a refund of the difference when the vehicle is checked out. A similar arrangement is already in place with the cost of road user charges on registration and deregistration. The amount of vehicle insurance is also paid accordingly. This cannot be arranged for the vignette only. Why?
