What happens if an officer fails to properly calibrate an SMD before use?

• A. The SMD becomes unusable
• B. The results are valid regardless
• C. The results may be contested in court due to questions of accuracy
• D. No impact, as calibration is not necessary

Answer: (C)

When an officer fails to properly calibrate a speed measurement device (SMD) before use, the primary consequence is that the results obtained from the device may be challenged in court due to concerns regarding their accuracy. Calibration is an essential process that ensures the device is measuring speed correctly. If not calibrated properly, the readings could be inaccurate, leading to potential legal disputes over the validity of the speed readings and, consequently, the enforcement actions taken based on those readings.

In a legal context, evidence from an improperly calibrated SMD can be argued as unreliable, making it difficult for the prosecution to prove the case beyond a reasonable doubt. This opens the door for defense arguments questioning the integrity of the speed measurement and can result in dismissed charges or findings in favor of defendants. Therefore, proper calibration is critical to both the legal standing of the SMD's results and the officer's ability to enforce speed regulations effectively.
