Drop Stop is a route constraint for when Stop A must come before Stop B, but the rest of the route can still optimize freely. After you set the constraint and run Optimize, RoadWarrior always places Stop A earlier in the sequence than Stop B.
Use this when one delivery must happen before another (pickup before drop-off, warehouse before first customer, and similar cases). For general optimization, see Optimize and route settings.
When should I use Drop Stop?
| Situation | Use Drop Stop? | | --- | --- | | Stop A must be visited before Stop B, other stops can reorder | Yes | | You want the fastest order for the whole route with no fixed pairs | No — run Optimize only | | Stop A must be first or last on the route | Consider Start and end points instead |
How do I set a Drop Stop?
Both stops must already be on the route before you add the constraint.
Add Stop A and Stop B to your route.
Tap Stop A (the stop that must come first).
Choose Set Drop Stop (or the equivalent constraint action).
Pick Stop B from the list (the stop that must come after Stop A).
Tap Optimize. Stop A stays before Stop B; other stops reorder around that rule.
Multiple Drop Stop rules
You can add more than one Drop Stop pair on the same route when several precedence rules apply. Run Optimize again after you change constraints or add stops so the sequence recalculates.
If optimization fails or the order looks wrong, confirm both stops have valid addresses and that the A-before-B rules do not conflict (for example, A before B and B before A on the same pair).
