An additional sign is a traffic sign placed directly below another sign to provide extra information or clarify how the main sign should be understood. It can specify conditions such as distance, time periods, road users affected, directions, or special circumstances. Additional signs do not create new rules by themselves but modify, limit, or explain the meaning of the sign above them so drivers can apply the rule correctly in that specific situation.

The supplementary sign local buses allowed indicates that only local public transport buses are permitted to access, enter, or use a road, lane, or area, even if it is generally restricted by the main sign. All other vehicles—including long-distance buses, private coaches, or general traffic—are not allowed, unless otherwise specified. May display text: “Except local buses”, “Local buses allowed”, “Only for public service buses”.
