Speeding is driving faster than the law allows. It is not just "going fast" — it is going faster than the number on the sign for that road. So 60 km/h can be perfectly legal on one road and speeding on the next one, because the limit changed, not because the car changed.

speeding是 driving faster than the law allows開車開得比法律規定還快。it is not just "going fast"這不只是「開得快」——it is going faster than the number on the sign for that road而是開得比那條路標示的速限還快。so 60 km/h can be perfectly legal on one road and speeding on the next one所以時速 60 公里在一條路上可能完全合法，換到下一條路就是超速，because the limit changed, not because the car changed因為速限變了，不是車子變了。

In this meaning the word is a noun, and it names the offence, the thing you can be punished for: you get a ticket for speeding, you get fined for speeding, the police stop you for speeding, a driver is charged with speeding. You will also see it in front of other words like an adjective — a speeding ticket, a speeding fine, a speeding offence — and all of those still point back to the same offence.

in this meaning在這個意思裡，the word is a noun這個字是名詞，and it names the offence指的是這項違規，the thing you can be punished for也就是會被處罰的那件事：you get a ticket for speeding你會因為超速被開單，you get fined for speeding因為超速被罰款，the police stop you for speeding警察因為超速把你攔下來，a driver is charged with speeding駕駛人因為超速被起訴。you will also see it in front of other words like an adjective它也會像形容詞一樣放在其他字前面——a speeding ticket超速罰單、a speeding fine超速罰款、a speeding offence超速違規——and all of those still point back to the same offence這些說的都是同一件違規。

Two things students find odd. First, it takes no article: we say "He was fined for speeding", never "for a speeding". Second, it is one of those crimes people admit to quite lightly. Someone will say "I was speeding a bit" the way they might say they were a few minutes late — it is against the law, but socially it sits far below drunk driving.

two things students find odd有兩件事學生常常覺得奇怪。first第一，it takes no article它不加冠詞：we say "He was fined for speeding"我們說 "He was fined for speeding"，never "for a speeding"絕不會說 "for a speeding"。second第二，it is one of those crimes people admit to quite lightly這是那種大家會很輕鬆承認的罪行之一。someone will say "I was speeding a bit"有人會說 "I was speeding a bit" the way they might say they were a few minutes late就像說自己遲到了幾分鐘一樣輕描淡寫——it is against the law, but socially it sits far below drunk driving這雖然違法，但在社會觀感上遠遠不如酒駕嚴重。

Though actually, in careful or formal use the tone hardens fast: a news report saying a driver was speeding is pointing at the cause of a death.

though actually不過事實上，in careful or formal use在講究或正式的場合 the tone hardens fast語氣會馬上變重：a news report saying a driver was speeding新聞報導說一個駕駛人在超速 is pointing at the cause of a death指的是造成一場死亡的原因。

Separately, speeding is also just the -ing form of the verb speed, so you meet the same letters in "a speeding car" (a car going very fast, no law mentioned) or "the ambulance was speeding to the hospital". There the word is only about speed, not about breaking a rule. Which one you are looking at usually shows in the sentence: after "for", it is the offence; in front of a vehicle, it is usually just fast.

separately另外，speeding is also just the -ing form of the verb speed也只是動詞 speed 的 -ing 形式，so you meet the same letters in "a speeding car"所以你會在 "a speeding car"（a car going very fast, no law mentioned一輛開很快的車，沒有提到法律）or "the ambulance was speeding to the hospital"或 "the ambulance was speeding to the hospital"（救護車正飛快趕往醫院）裡看到一樣的拼法。there那時候 the word is only about speed, not about breaking a rule這個字只是在講速度，跟違規無關。which one you are looking at usually shows in the sentence你看到的是哪一種，通常句子裡就看得出來：after "for"在 "for" 後面，it is the offence指的是違規；in front of a vehicle放在交通工具前面，it is usually just fast通常就只是在說很快。
