What is 10% over the speed limit of 120?

[LaEvangeline]

Exceeding the speed limit of 120 by 10% results in a speed of 132. Specific details are as follows: 1. Penalties: When driving on roads with a speed limit above 100, exceeding the limit by 10% but less than 50% will result in a certain fine and deduction of relevant points. However, violations exceeding the speed limit by less than 10% will only receive a warning without any fine or point deduction. It is important to note that on highways with a speed limit of 120, exceeding the limit by less than 10% does not incur a fine or point deduction, meaning the maximum speed on a 120 highway is effectively 132. 2. According to Article 42 of the Road Traffic Safety Law of the People's Republic of China: Motor vehicles driving on roads must not exceed the maximum speed indicated by speed limit signs. On roads without speed limit signs, a safe speed should be maintained. Driving speed should be reduced when driving at night, on dangerous road sections, or under adverse weather conditions such as sandstorms, hail, rain, snow, fog, or icy conditions.

That time on the highway, the speed limit was 120 and I drove at 132, almost getting a ticket. Actually, exceeding by 10% means 120×10%=12 km, so 132 is the critical point for speeding. I know that generally, speeding within 10% only results in a warning without penalty points, but regulations vary by region—some places issue tickets for even 1 km over. My car has a radar detector that beeps as soon as I exceed the speed limit, which is really handy. Later, I calculated that braking distance at 132 is several meters longer than at 120, making it especially dangerous if someone brakes suddenly ahead. Now, I strictly adhere to the speed limit, because safety is far more important than saving a few minutes. I recommend setting up a speeding alert on your navigation system—don’t gamble with safety.

From a mathematical perspective, it's straightforward: exceeding the speed limit by 10% equals the limit multiplied by 0.1. For a speed limit of 120, 120×0.1=12 km/h, so 132 is the upper threshold. Interestingly, the speedometer typically displays a speed 3%-5% higher than the actual speed; for instance, a displayed 132 might only be 127 in reality. However, this discrepancy can't be used as an excuse. Last year, a friend of mine thought 130 was fine but was clearly caught by a speed camera. Exceeding 132 results in at least 3 penalty points and a 200-yuan fine. More critically, the risk doubles—the impact energy at 132 km/h is 21% higher than at 120, and the probability of a tire blowout also increases significantly. Nowadays, I keep my eyes glued to the HUD display, careful not to exceed even slightly.

As a beginner driver, I was particularly afraid of speeding. Every time I saw a speed limit sign, I'd mentally calculate: 10% of 120 is 12, so 132 is the red line. My instructor said that while exceeding the speed limit by 10% doesn't incur demerit points, insurance might deny claims if an accident occurs. Once during rain, I drove at 128 km/h and the wheels skidded, nearly causing a loss of control. That scared me so much that I now always use cruise control set at 118 km/h. Don't underestimate the 12 km/h difference – braking from 120 km/h requires 66 meters, but from 132 km/h it takes over 80 meters. If an animal suddenly darts out, you simply won't have enough time to stop. I recommend new drivers place their phone mounts in a visible position to monitor real-time speed via navigation, and avoid playing music too loudly as it can interfere with judgment.
