As illustrated above, the Normal Design Domain warrants require an AUL(s) type treatment (auxiliary left turn
lane - short) for the left turn. Conversely if considering the Extended Design Domain, the intersection
warrants only a BAL (Basic left turn).
To be conservative, the Normal Design Domain should be used in the first instance. So to provide an AUL(s)
type treatment is normally uncommon for property accesses, except those with very high turning movements
usually from major roads.
An AUL(s) treatment is illustrated below.
