The legality of exceeding the speed limit by a certain amount varies depending on the jurisdiction and specific laws in place. Speed limit laws are set by local authorities and can differ between countries, states, and even municipalities. It is important to familiarize yourself with the specific speed limit laws in your area.
In many jurisdictions, exceeding the speed limit, even by a small margin, can be considered a violation of traffic laws. The extent to which exceeding the speed limit is tolerated before enforcement action is taken can also vary. Some jurisdictions have a tolerance range where law enforcement may allow a slight margin above the speed limit due to factors such as speedometer error or other practical considerations. However, it is important to note that this tolerance is not universally applied, and exceeding the speed limit, even by a small amount, can still result in a traffic violation.
To ensure compliance with the law, it is generally recommended to adhere to the posted speed limit and adjust your speed based on the road and traffic conditions. It's always a good practice to prioritize safety and follow the speed limits established for the area you are driving in.
