What is the percentage of speeding when driving at 85 in an 80 speed limit zone?

[OWilliam]

Driving at 85km/h in an 80km/h speed limit zone is considered speeding, with a speeding ratio of 6.25% (calculation method: (85-80) ÷80x100%=6.25%). Relevant information about speed limits is as follows: 1. Introduction: Speed limits typically refer to the regulation of vehicle speeds within a certain numerical range over a specific distance. They are imposed to maintain normal, stable, and safe production orders and operational processes by setting necessary speed restrictions on various mechanical and electrical equipment and manual operations, thereby preventing accidents or malfunctions caused by overloading or other reasons. 2. Purpose: The primary goal is to preemptively remind drivers to reasonably control their speed in subsequent sections of the road ahead and to prevent the dangers of speeding. Speed limits are an indispensable and most crucial aspect of road transport safety.
