Which issue would lead to rejection of a speedometer or odometer?

A speedometer or odometer is critical for ensuring that vehicle performance and mileage tracking are functioning properly. If any aspect of these instruments is not working correctly, it could lead to a rejection during a Maryland state inspection.

Illegible dials and issues with calibration can prevent an accurate reading of speed or distance traveled, making it impossible for the driver to know how fast they are going or how far they have traveled. This affects both safety and compliance with traffic laws.

If the odometer does not register distance traveled, it would not provide the necessary information regarding how many miles a vehicle has been driven. This can have implications for maintenance and resale value, as accurate mileage is essential for both assessing vehicle condition and adhering to service schedules.

Additionally, if the speedometer fails to register speed in either miles or kilometers, the driver cannot gauge their speed, which can lead to unsafe driving conditions and potential traffic violations.

Considering these factors, any of these issues would justify a rejection of the speedometer or odometer during an inspection. Therefore, having any one of these defects is significant enough to fail the inspection, affirming that all aforementioned issues contribute to the overall decision to reject the instrument.
