FASTag falls but GPS doesn't: route changes

The pattern

FASTag tells us when a vehicle crosses a toll plaza. A truck on a highway crosses several a day; a pickup doing city deliveries may cross none. When a fleet moves from inter-city runs to intra-city work, toll crossings collapse while the vehicles are busier than ever.

How we found it

In early 2026 a group of pickup fleets in Bengaluru showed FASTag trips down 60% or more in a month. Several were heading for Watch. Field visits found every vehicle working: a quick-commerce platform had consolidated its delivery routes inside the city, and the fleets had followed the contracts. GPS running hours on the same vehicles were up, not down.

The rule we added

The EWS now applies M1 (minus 15 points) when GPS running hours are steady or up while FASTag trips fall. A fleet with the toll fall alone stays visible, but at Emerging rather than Watch.

Before you act on a FASTag fall

1. Look at GPS hours, if a device is fitted. Steady or rising: a route change. Falling: the vehicle is idle.
2. Look at the news feed for route or contract changes in the city.
3. Call the operator and ask where the vehicles are working now.
4. Keep chasing the other signals as usual. A route change doesn't renew an insurance policy.

Worked example

A 12-pickup fleet: FASTag trips down 64% (U1, 20), one NACH bounce cleared the next day (R1, 10), insurance lapsing on one pickup (C1, 12), two new loans elsewhere (B2, 8), six unpaid e-challans (C5, 5). Score 55, Watch. GPS running hours up from 8.4 to 9.2 a day: M1 applies, and the score is 40, Emerging. The right action was an insurance reminder, not a field visit.
