When it is illegal to cross a road, indicated by a ''widened'' yellow section or an uncrossable barrier in the middle, and has roads connecting to it, it must be divided.
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 [[Thailand#U-Turns|U-Turn connector]].  In order to assure proper routing in Waze, these roads must be divided.
This prevents a lot of red/green arrow twiddling.

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)
