The enforcement of speed limits and the tolerance for minor speed infractions can vary depending on local laws, regulations, and the discretion of law enforcement officers. While I can provide some general information, it's important to note that specific practices and policies may differ between jurisdictions.
In many places, law enforcement officers exercise some discretion when it comes to enforcing speed limits. They often consider a margin of error or tolerance for minor speed variations, typically referred to as the "speedometer error" or "calibration error." This error accounts for slight discrepancies between the displayed speed on a vehicle's speedometer and the actual speed traveled.
If you are going slightly over the speed limit by a small margin, such as 0.5 miles per hour, it's less likely that you would be pulled over for such a minor infraction. Law enforcement officers often focus their attention on more significant speed violations or hazardous driving behaviors. However, it's important to remember that discretion can vary among officers, and they may choose to enforce the speed limit strictly, even for minor violations.
Additionally, keep in mind that factors such as the road conditions, presence of pedestrians, the flow of traffic, and any additional driving infractions can also influence an officer's decision to pull someone over.
To ensure compliance with the law and avoid potential penalties, it is generally advisable to adhere to posted speed limits and drive safely and responsibly at all times.
