이/가 is the subject marker. In 경찰이, it marks the police as the doer of the actions in the sentence.

Here, 경찰이 means that the police are the ones who:

• checking the scene
• handling the traffic accident

If you changed it to 경찰은, that would make the police the topic instead. That can still be grammatical, but the nuance changes a little:

• 경찰이: focuses on who did it
• 경찰은: introduces the police as the topic and says what they did

In a neutral sentence like this, 이/가 is very natural.

The 을/를 particle marks the direct object of a verb.

So in 현장을 확인하고:

• 현장 = the scene / site
• 을 = object marker
• 확인하다 = to check / confirm

That means 현장을 is the thing being checked.

A useful way to think about it:

• 경찰이 = who did it
• 현장을 = what they checked
• 교통사고를 = what they handled

확인하고 is the verb 확인하다 with -고, a connector that links verbs.

Breakdown:

• 확인하다 = to confirm, check, verify
• 확인하고 = check/confirm and...

So 현장을 확인하고 교통사고를 바로 처리했어요 means the police:

1. checked the scene
2. then handled the accident

In many cases, -고 simply links two actions as and. It often suggests sequence when the actions naturally happen one after the other, as they do here.

This is a very common Korean pattern.

In connected verb chains, only the final verb often carries the tense marking, while earlier verbs stay in a neutral connective form.

So:

• 확인하고
• 처리했어요

Even though 확인하고 does not visibly show past tense, the whole sentence is understood as past because the final verb 처리했어요 is in the past tense.

This is normal Korean grammar. You do not need to say 확인했고 처리했어요 unless you specifically want a slightly different structure or emphasis.

Here, -고 connects two actions and is best understood as and or and then.

In this sentence, it has a natural sequential feeling:

• checked the scene
• then handled the accident

But -고 does not always strongly mean after that in a strict timeline sense. Sometimes it just lists actions. Context tells you whether it feels like:

• simple addition: and
• sequence: and then
• paired actions: do X and Y

In this sentence, because checking the scene logically comes before handling the accident, English often renders it as and then even though Korean just uses -고.

Again, 를 is the object marker.

In 교통사고를 바로 처리했어요:

• 교통사고 = traffic accident
• 를 = object marker
• 처리하다 = to handle, process, deal with

So the traffic accident is the thing being handled.

This may feel a little unusual to an English speaker because English often says handle the accident or deal with the accident, and Korean does the same idea with a direct object: 교통사고를 처리하다.

바로 often means:

• right away
• immediately
• directly
• exactly

In this sentence, the most natural nuance is right away / immediately.

So it tells you that the police handled the accident promptly, without delay.

Position-wise, 바로 comes before the verb it modifies:

• 바로 처리했어요 = handled it immediately

처리했어요 is:

• 처리하다 = to handle / process / deal with
• 했어요 = past tense + polite speech

So this is the polite past form.

Breakdown:

• 처리하다
• 처리해요 = polite present
• 처리했어요 = polite past

This style is often called 해요체, which is a common polite conversational style.

Korean is basically an SOV language:

• Subject – Object – Verb

So instead of English-style word order:

• The police checked the scene and handled the accident

Korean naturally puts the verb later:

• 경찰이 현장을 확인하고 교통사고를 바로 처리했어요

This is one of the biggest structural differences between English and Korean. In Korean, the most important grammatical information, especially tense and politeness, often appears near the end.

Yes, depending on context, 경찰 can refer to:

• the police
• a police officer
• police as an institution

Korean nouns often do not show singular/plural unless it matters.

So 경찰이 could mean:

• the police
• a police officer
• police officers

You figure it out from context. In a sentence like this, English may translate it as the police because that sounds natural, but Korean itself does not force that exact number.

In casual spoken Korean, particles are often omitted when the meaning is clear. For example, people may sometimes drop 이/가 or 을/를 in conversation.

However, in a full written sentence like this, keeping the particles is natural and standard:

• 경찰이
• 현장을
• 교통사고를

For learners, it is usually best to keep the particles until you become comfortable with when omission sounds natural.

Yes, 처리하다 is commonly used for handling, processing, or dealing with situations, tasks, cases, paperwork, and incidents.

With 교통사고, it can mean something like:

• handle the accident
• deal with the accident
• process the accident case

It sounds a bit official or administrative, which fits well with police activity.

So this sentence has a slightly formal, report-like feel, even though -어요 makes it polite and conversational in form.
