| | ABD - Speed Limit Signing Requirements |
 | | On motorways where the normal speed limit of 70mph applies, therefore, the only speed limit signs required are those to diagram 670, showing the figure "70", at the point where a motorway starts and at the start of every entry slip road. |
 | | If the permanent speed limit changed at some point along the length of the temporary restriction, however, signs to diagram 670 (maximum speed limit) or 671 (national speed limit) must be shown in addition, to show what the permanent speed limit is as drivers leave the temporary restriction. |
 | | For example, a speed limit sign to diagram 670 is round with a white background, red border and fl numerals: if mounted on a yellow or grey board, the sign's background must still be white and not the colour of the board. |
