Missouri Highway Types
Missouri has two types of state highways: primary (numbered) and supplementary (lettered). The table below shows the minimum classification for state highways. These are only minimums and may need to be upgraded based on the Functional Classification or the qualities defined on the USA road type Wiki page.

State Highway Naming
Missouri primary numbered highways are named as MO-### (e.g. MO-13, MO-7 N). This includes their related business, loops, and spurs. (e.g. MO-13 BUS)
Missouri secondary lettered highways are named as State Hwy xxx. (e.g. State Hwy F)
County Road Naming
County roads with the name designation of "County Road ###" are named as CR-### (e.g. CR-110). This shortened version takes up less space on the map screen and is announced correctly as "County Road ###" while navigating with the Waze app.
Functional Classifications
Missouri follows the Functional Classification (FC) system for the USA. Base minimum road types in the Waze editor according to the MoDOT Highway Functional Classification Maps along with guidance from the USA road type guidelines.
The table below shows a cross reference for the minimum road types in Missouri. Keep in mind that these are only minimums, and may need to be upgraded based on the qualities defined on the USA road type guidelines.
| MODOT Classification | Waze Road Type |
|---|---|
| Interstate | Freeway |
| Expressway | Major Highway |
| Principal Arterial | Major Highway |
| Minor Arterial | Minor Highway |
| Urban Collector | Primary Street |
| Rural Major Collector | Primary Street |
| Rural Minor Collector | Primary Street |
| Local Road | Street |
Lock Levels
In Missouri we have a set minimum standard for locking roads based on segment type. Any road of a certain segment type must be locked at least to the rank (level) in the chart below. Roads may be locked higher for protection and special situations (areas with construction, tricky design, frequent mistakes, imaging inaccuracies, and the like), but should not be locked lower.
A great time to implement these locks is while bringing the road types of an area into compliance with the current US road type standards (FC and highway systems). Lock the roads based on type after they've been set to current US road type standards.
