According to State V. Tomanelli, what is the acceptable margin of error for speed measurement?

In State V. Tomanelli, the acceptable margin of error for speed measurement is established as within ± 1 mph. This standard is significant because it provides a defined and reasonable range within which speed measurements can be considered accurate. The rationale behind this margin is to account for potential discrepancies that may arise from various factors, such as environmental conditions, equipment calibration, and operational variables.

Having a margin of ± 1 mph allows for a level of precision that ensures the reliability of speed enforcement while also recognizing the inherent limitations of measurement devices. It reflects a balance between the need for accurate speed assessments in traffic enforcement and the acknowledgment of real-world variances in measurement accuracy. By adhering to this standard, law enforcement can maintain the integrity of speed-related tickets and citations, as well as ensure that they are on firm legal ground in prosecutions related to speeding offenses.
