| 138 | | A couple of other points about creating ways. |
| 139 | | |
| 140 | | 1. Dual-carriage ways (divided roads such as motorways, interstate highways, etc.) should be drawn as two separate parallel ways, with each carriage way being a different direction. |
| 141 | | 1. If a street is one-way (including the individual carriage ways of a dual-carriage way), that way '''should be drawn in the direction of travel'''. |
| 142 | | 1. Key-and-value tagging is case sensitive. All keys should be entered in '''lower case'''. |
