Merge adjacent same-category segments

Sometimes a drive gets auto-split into two chunks that should really be one — a two-minute stop at a light broke the "same category" streak in the middle of a City Driving stretch. Merge puts them back together.

Trip Summary showing the map, stats bar, and the top of the Practice Activities list. A merge pill appears between two adjacent same-category segments when present.

1 Merge pill (between two cards). A small "Merge ↕" pill appears only when the segment above and below share the same TDLR category. If you don't see one, the two neighbors have different categories — reassign one first if you want them merged.

When the merge pill shows up

The merge pill is a one-tap shortcut — it only appears when it's safe to use. Specifically:

Two segments must be adjacent in time — no other segment between them.
Both must be assigned the same TDLR category.
Either both are day or both are night. A "day" segment next to a "night" one won't offer a merge, because the TDLR form tracks day and night separately.

Why segments get split in the first place

LearnerLog categorizes by rolling speed. A long, steady highway drive can briefly dip below the expressway threshold at a construction zone or toll plaza, which creates a new segment. When you reassign that little chunk back to Expressway, it becomes mergeable with its neighbors.

The reverse — if you merged something you shouldn't have

A merge isn't destructive. Use Split Time on the resulting segment to break it apart again. You won't get the original split-points back automatically, but you can re-split by minute count into any shape you like.

Tip: If you're using Reassign a segment and suddenly see merge pills appear, that's the feature telling you "these now match, want to clean them up?" Tapping once leaves the Trip Summary tidier and the TDLR-form readout easier to read.
