Additional signs
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.

3. For skiers
The supplementary sign for skiers is a panel placed immediately below a main traffic sign to indicate that the main sign’s message applies only to skiers (e.g., on a ski slope, cross-country track, or winter path). It restricts or clarifies the scope of the main sign so that only skiers must obey the instruction or warning.

4. For cyclists
The supplementary sign for cyclists is a panel placed below a main traffic sign to indicate that the rule, warning, or instruction applies specifically to cyclists. It limits the scope of the main sign only to bicycle users, ensuring that other road users are not affected unless separately indicated. Example: No entry + for cyclists = cyclists are not allowed to enter, but other traffic may proceed.
