Less than 10% over the speed limit. Below is a detailed explanation of speeding penalties: 1. Less than 10%: A warning will be issued without any points deducted or fines imposed. 2. 10% to 20% over: 3 points will be deducted. 3. 20% to 50% over: 6 points will be deducted. 4. More than 50% over: 12 points will be deducted from the driver's license. The fine amount will then gradually double as the speeding increases, up to more than 100% over the speed limit.

As a seasoned driver, I have deep insights into speed control. When the speed limit is 80 kilometers per hour, driving at 87 km/h means exceeding the limit by 7 km or about 8.75%. This small figure may seem insignificant, but it hides significant risks. The braking distance increases by several meters, especially in rainy conditions or emergencies, making rear-end collisions more likely. I remember a colleague who hit a guardrail just by driving 5 km over the speed limit, costing thousands in repairs. Statistics show that speeding within 10% increases accident probability by 15-20%. That's why I always keep my speed within 5 km below the limit—never rush for momentary gains. Additionally, speeding increases fuel consumption and harms the engine over time. The difference between 87 and 80 is a simple math problem of 7 km, but real driving demands greater caution—life is priceless.

I have learned lessons from my driving practice. When the speed limit is 80 km/h and driving at 87 km/h, exceeding by 7 km/h is approximately 8.75%. Many people don't care about such minor speeding, but the cumulative consequences can be severe. Take traffic tickets as an example: exceeding the speed limit by 10%-20% often results in a fine of 100-200 yuan. Although no points are deducted, it wastes time to deal with it. I once got fined for exceeding by just 6 km/h, and my insurance premium also increased slightly. Economically, driving 7 km/h faster increases fuel consumption by 3%, accelerates tire wear, and raises maintenance costs. I recommend using in-car navigation or apps to monitor speed and avoid unknowingly exceeding the limit. The difference between 87 and 80 is 7 km/h. Calculating the risks shows it's not significant, but safety always comes first—better safe than sorry.

Studying car data is my interest. With a speed limit of 80 km/h, driving at 87 km/h means exceeding the limit by 7 km, a ratio of (87-80)/80×100%=8.75%. The dashboard may have errors, and the actual speed might be 85-89 km/h, so using GPS for measurement is more accurate. Exceeding the speed by around 9% is often overlooked by traffic cameras, but 8.75% is close to the threshold, increasing the chance of being caught. During acceleration, air resistance is significant, increasing fuel consumption by about 5%, and the engine temperature rises, making it prone to overheating. I've tested similar situations and recommend adjusting the cruise control to reduce by 2 km to compensate for errors. Subtracting 80 from 87 gives a difference of 7 km, a simple numerical value, but its application needs to consider road conditions and changes in regulations—driving slower is more stable.

As a family driver, I always prioritize safety when driving. Driving at 87 km/h in an 80 km/h speed limit zone means exceeding the limit by 7 km or 8.75%. This slight overspeed is too dangerous when carrying my wife and children: for every 5 km/h increase in speed, the chance of an accident rises by nearly 20%, and the braking distance lengthens, making it easier to hit people or vehicles. Legally, exceeding the speed limit by less than 10% may result in a fine of 100 yuan, affect insurance costs, or require safety education. Economically, it consumes more fuel and harms the environment. I teach my children that driving isn't about saving minutes, but about arriving safely. In daily practice, I set speed reminders to prevent the 7 km difference between 87 and 80 from turning into a major mistake. Data supports this view, and following the rules brings peace of mind.
