Definition of H24

H24 - Auto-estrada (Auto-estrada) belongs to the Portuguese information signs category in the Regulamento de Sinalização do Trânsito.

The official wording is: auto-estrada: indicação de entrada numa auto-estrada, vigorando na mesma, por consequência, as regras de trânsito especialmente destinadas a esse tipo de vias. It gives official information about the road environment, services, restrictions, facilities, or conditions that should influence safe planning.
