Dividing roads
In Thailand, many roads have an uncrossable median, requiring drivers trying to get to a location on the other side of the road to drive past their location and make a U-turn at an intersection or designated U-Turn connector. In order to assure proper routing in Waze, these roads must be divided.
These uncrossable medians are indicated by a widened yellow section or an uncrossable barrier in the middle.

Do not divide:
If the road has already been drawn in as a single two way segment, care should be taken when dividing to preserve any existing traffic history assigned to those segments. Here is a tutorial on how to divide a road and preserve existing traffic history and street numbers. (Tutorial link to be added soon)
