Although speeding is indicated in red, it does not necessarily result in a fine. According to relevant regulations, if the speed exceeds the limit by less than 10%, traffic police will not impose a penalty but will only issue a warning. Function of Digital Speed Displays: Digital speed displays intuitively alert passing vehicles of their current speed through changes in numbers and colors. This encourages drivers to consciously control their speed, effectively reducing road accidents caused by speeding. Application of Digital Speed Displays: The automotive digital speed feedback device stands 2.5 meters tall and 0.95 meters wide. The upper part of its front side displays the speed limit, while the lower part features an LED screen showing "real-time speed." The radar speed feedback device operates on solar power, with solar panels and batteries ensuring continuous operation during nighttime and rainy conditions, enabling 24-hour monitoring of vehicle speeds along the road.

As a seasoned driver with twenty years of experience, I'm quite familiar with those speed display signs on the roadside. They are purely informational displays and don't directly issue fines; for example, when they show you're speeding, they just serve as a reminder tool, unlike cameras or police officers who actually issue tickets. I often see these on highways, and every time it flashes red, I slow down, but I've never been fined because of it. Real fines come from enforcement devices like roadside radar or surveillance cameras. Occasionally, there might be hidden speed traps near the display signs, and speeding could land you in trouble, so I recommend getting into the habit of checking actual speed limit signs rather than waiting for the screen warning. Safe driving is the key—speeding carries high risks of causing accidents.

As a commuting office worker, I find roadside speed display signs like little helpers on the road. They only show your speed, and if it indicates speeding, it's just reminding you to slow down without recording your license plate or issuing fines. I see them every day on urban expressways - green light for normal speed, red light warning for speeding - very intuitive. Fines come from official systems like police cars or automatic cameras, so don't mistake these displays for traps. Actually, using them to adjust your speed helps develop good habits that save fuel and improve safety. Just slow down a bit when you see them, and you can avoid trouble.

As a car enthusiast, I'm interested in how these devices work. Roadside speed display signs are essentially radar feedback devices—they only read and display vehicle speeds on electronic boards without actively issuing penalties. They operate separately from law enforcement systems; fines require either camera captures or police intervention. I've noticed they help cultivate self-discipline to avoid speeding accidents. As long as you slow down promptly, everything's fine. Safety comes first.
