1. It is recommended that the trans-continental and interstate routes of major importance, as selected by the Joint Board and shown on the map accompanying this report, be hereafter known as "United States Highways."

2. It is further recommended that the system of designation by numbers, as shown on the map referred to, be adopted, as a means of designating the routes selected.

3. It is further recommended that a distinctive marker, as shown by the photograph marked Exhibit A, be adopted for use by all the States in marking the designated routes on the ground. The term "Marker" is used to indicate only the shield with the number, and all warning, caution and directional signs are indicated by the term "Sign".
