What are the penalties for interval speeding?

[RoseLynn]

Points deduction and fines. Below is relevant information: 1. Margin of error: The speedometer inside the vehicle always shows a higher speed than the actual detected speed outside, because wind resistance and tire friction reduce speed, while the speed displayed inside is the engine output speed. For example, if the dashboard shows 60 mph, the actual speed might only be 55 mph. In fact, speed cameras on highways also have a margin of error, typically around 2%, and it's usually a lagging error. 2. Speed limits: Speed limit signs are scientifically set based on actual traffic conditions, roadside facilities, etc., to provide accurate and timely information; through the guidance of speed limit signs and other traffic signs, drivers can reach their destinations smoothly and quickly.
