Segnali di divieto e limitazione

Divieto di sorpasso

Non sorpassare i veicoli a motore delle categorie interessate dal segnale.

Il segnale vieta di sorpassare i veicoli contemplati dalla norma locale. Le eventuali eccezioni per determinati veicoli, comprese le motociclette, dipendono dal paese.

I modelli diffusi in Europa raffigurano un’auto rossa accanto a un’auto nera all’interno di un disco con bordo rosso. Il segnale statunitense R4-1 è un pannello rettangolare bianco con la scritta nera Do Not Pass.
