GeoTab evidence becomes useful when the correct vehicle and actual telemetry timestamp are clear. A recent connection check does not make an older vehicle reading live.
Confirm the vehicle link
Check known vehicle identities and source readings within your company and station. A connection alone does not establish correct links for every vehicle.
Respect measurement limits
Use measured fuel and valid odometer readings. Warning lamps are not fuel percentages, and unavailable sensors should not produce invented values.
Review history and events
FillUp-based consumption requires supported plausible complete-tank intervals. Possible collision events need confirmation. Old history must not replace newer position evidence.
