Specific Texas guidelines
- Be sure to know when not to split a two-way road
- FM Roads not grouped into functional class are to be set to Primary Street east of US-281 and north/east of I-37. All other FM roads are set to Minor Highway .
- Dirt Roads. In Texas ALL roads that are normally unpaved are considered dirt roads as this is how GPS Nav users (any brand) expect the "Avoid Dirt Roads" feature to behave. These roads should be deleted when going through farm land, ranch land, or mountainous areas throughout the state, as they are most likely base import roads and not real roads.
- Frontage roads not classified as Primary Street by functional class are to be classified as Street . They are also to be labeled "Frontage Rd" unless the corresponding highway has an alternate name. I-635 Frontage roads are labeled as "Lyndon B Johnson Freeway" as that is the local name for I-635.
- Alleys and driveways are NOT MAPPED
- All freeways are set to ground level. If two freeways cross each other, look at the actual intersection to discover the layers of the intersection.
- U-turns are labeled as "turnaround."
