Non devi sorpassare vicino alla curva.

Devi is the second-person singular form of dovere = to have to / must.

So:

• devi = you must / you have to
• non devi = you must not / you shouldn’t

In this sentence, non devi sorpassare means something like:

• you must not overtake
• you shouldn’t overtake

A useful note: in Italian, non devi often sounds like a prohibition or strong advice, not just the absence of necessity.

Because after a modal verb like dovere (must / have to), the next verb normally stays in the infinitive.

So the pattern is:

• dovere + infinitive
• potere + infinitive
• volere + infinitive

Examples:

• Devi studiare = You must study
• Puoi entrare = You can come in
• Vuoi mangiare? = Do you want to eat?

So in your sentence:

• devi sorpassare = you must overtake
• non devi sorpassare = you must not overtake

Sorpassare usually means to overtake / to pass another vehicle.

In a road-safety context, it is the natural verb for overtaking.

A useful comparison:

• sorpassare = to overtake, especially in traffic
• superare = to pass, overcome, exceed; broader meaning

So here sorpassare is the best choice because the sentence is about driving.

Because vicino is commonly followed by the preposition a when it means near.

So:

• vicino a = near

Then a + la becomes alla:

• vicino a la curva → vicino alla curva

This is standard Italian.

Examples:

• vicino alla scuola = near the school
• vicino al ponte = near the bridge
• vicino ai negozi = near the shops

Because curva is a feminine singular noun.

The article is:

• la curva = the curve / the bend

And after a, it combines like this:

• a + la = alla

So:

• vicino alla curva = near the bend

If the noun were masculine singular, you would get al instead:

• vicino al ponte = near the bridge

It can mean curve literally, but in road contexts it is often best translated as:

• bend
• sometimes curve

Depending on context, English might use corner, but bend/curve is usually closer here.

So vicino alla curva is naturally understood as:

• near the bend
• near the curve in the road

This is a very common question.

In many cases, non devi + infinitive is understood as:

• you must not
• you shouldn’t

If you want to clearly say you don’t have to, Italian often uses other wording, such as:

• non c’è bisogno di...
• non sei obbligato a...
• non devi per forza...

So in this sentence, Non devi sorpassare vicino alla curva is naturally understood as a warning/rule, not as you don’t need to overtake near the bend.

Yes. Italian word order is fairly flexible.

The neutral order here is:

• Non devi sorpassare vicino alla curva.

But you could also say:

• Vicino alla curva non devi sorpassare.

That puts more emphasis on near the bend.

Both are grammatical, but the original sentence sounds very natural and straightforward.

Yes. Instead of non devi sorpassare, Italian could use a direct command:

• Non sorpassare vicino alla curva.

That means:

• Don’t overtake near the bend.

The difference is tone:

• Non devi sorpassare... = rule, obligation, instruction
• Non sorpassare... = direct command

Both are common, especially in driving or safety contexts.

Yes: non goes directly before the conjugated verb.

So:

• devi = you must
• non devi = you must not

This is the normal way to negate a sentence in Italian.

Examples:

• Parli italiano. = You speak Italian.
• Non parli italiano. = You do not speak Italian.

So in your sentence, non negates devi, giving the idea you must not.

A simple pronunciation guide is:

Non DEH-vee sor-pas-SA-re vee-CHEE-no AL-la KOOR-va

A few useful points:

• devi = DEH-vee
• sorpassare has stress on -sa-
• vicino = vee-CHEE-no
• curva = KOOR-va

Also remember:

• Italian c before i in vicino sounds like ch in cheese
• Italian r is usually rolled or tapped
