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.
