Previously, it was reported that inexperienced drivers were obliged to put special signs on their cars. The Road Safety Service of the Public Safety Department under the Ministry of Internal Affairs reported this.
A yellow, 150-millimeter-wide sign with an exclamation mark image "!", can be installed at the discretion of the driver in vehicles driven by learner drivers, or those who have not yet gained much experience driving and also those people with less than 2 years driving experience.
However, it is forbidden to write other inscriptions on the glass of the car. Banners for advertising purposes are the exception.
For reference, the new version of the traffic rules will come into force on 1 May 2022.
