What must a dealer write on the contract if they know the odometer is inaccurate without further indication of true mileage?

When a dealer is aware that the odometer reading is inaccurate but can’t provide the true mileage, the appropriate indication to include on the contract is "TMU," which stands for "True Mileage Unknown." This designation is crucial as it informs potential buyers that the recorded mileage cannot be trusted, thereby ensuring transparency in the sales process and protecting both the dealer and the consumer.

Using "TMU" communicates a lack of certainty regarding the actual mileage of the vehicle, which is important to disclose because the vehicle's odometer reading plays a significant role in determining its value, maintenance needs, and overall condition. By indicating that the true mileage is unknown, the dealer safeguards themselves against legal ramifications that could arise from concealing information about the vehicle’s actual history.

Other options, such as "TMI" or "MI," would imply varying levels of accuracy or uncertainty about the odometer reading, which would not reflect the dealer's specific knowledge of inaccuracy. "N/A" could lead to confusion, as it doesn’t clarify the status of the odometer at all. Thus, using "TMU" is the most appropriate and legally compliant choice when the dealer cannot provide an accurate odometer reading.
