The standard sequence (that I know of) is as follows
- Left turn coming from north/south
- Straight and right turn coming from north/south
- Left turn coming from east/west
- Straight and right coming from east/west
- Straight and right turn coming from north/south
- Left turn coming from north/south
- Straight and right coming from east/west
- Left turn coming from east/west
Epic mod by the way!
