Functional Classifications
California is following the Functional Classification (FC) system for the USA.
To help update the current California roadways to the new functional classifications, go to the California FC update page.
Here is a bookmarklet (currently under beta test) which will locate the correct CRS Grid page for the area you are editing in.
Lock Levels
We observe the following minimum lock levels for Waze road types:
| ROAD TYPE | LOCK LEVEL |
|---|---|
| Freeway | 5 |
| Ramp | 5 |
| Major Highway | 3 |
| Minor Highway | 2[1] |
| Primary Street | 2 |
| All Others | 1 |
Additional:
- ↑ Increase lock level to 3 in dense metropolitan areas
Note that these are minimums and, for protection, certain segments may be at higher lock levels.
U-turns
This is interim guidance for California, until such time as National standards are agreed upon.
U-turns on *two-way* Primary Street through Major Highway type roads may be enabled in either of the following two circumstances:
- 1) The U-turn is _explicitly_ allowed by signage; or
- 2) The U-turn is otherwise legal and safe, and there is _at least_ 10.1 m (33 feet) from the left edge of the departure lane to the "destination" curb. This can include any median that may exist to the left of the departure lane. (The measurement is intended to accommodate the turning radius of most passenger vehicles.)
Do NOT make a point of enabling all U-turns valid under this guidance, only as you encounter them and they are necessary. Do not enable U-turns on Street type roads. This guidance could change in the future.
