# Odometer anomaly guideline

## 1. Lower reading

If a new reading is lower than the canonical odometer, preserve the submitted reading as evidence but do not lower the canonical value. Check for digit transposition, incorrect vehicle selection or a source-system import error.

## 2. Resolution

An Operations Manager may resolve the issue after checking the original inspection. Correct only the erroneous inspection or source mapping; do not rewrite valid historical readings.

## 3. Escalation threshold

Any unexplained reduction or a single increase above 2,500 kilometres during one rental requires review.
