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 for personal transporters is a traffic panel placed beneath a main sign to indicate that the regulation or instruction applies specifically to personal transporters. It limits or defines the main traffic sign’s scope to users of personal transporters, such as: segways, electric self-balancing scooters or similar low-speed, single-person electric mobility devices. It improves clarity for all road users and enhances safety for emerging forms of micromobility.
