차선을 = 차선 + 을

• 차선 means lane or traffic lane
• 을 is the object particle

So 차선을 확인하고 literally means check the lane or check the traffic lane markings/lane position.

Because 차선 ends in a consonant, it takes 을 rather than 를.

확인하고 comes from the verb 확인하다, which means to check or to confirm.

The -고 ending connects one action to the next. In this sentence, it means something like:

• check the lane and practice parallel parking
• after checking the lane, practice parallel parking

So 확인하고 is the connector form of 확인하다.

A very natural way to understand it is:

• Action 1: check the lane
• Action 2: practice parallel parking

Here, -고 links two verbs in sequence.

So:

• 확인하고
• 연습합니다

means check ... and practice ...

In many cases, -고 can mean simple and, but in context it often suggests that one action happens before the next. Here, the natural sense is:

• Check the lane, then practice parallel parking.

It is a very common way to connect verbs in Korean.

Korean often leaves out the subject when it is obvious from context.

So this sentence could mean:

• You check the lane and practice parallel parking
• We check the lane and practice parallel parking
• One checks the lane and practices parallel parking

In a textbook, driving lesson, or instruction manual, the omitted subject is often understood as you or as a general instructional subject.

This is completely normal in Korean.

평행 주차 means parallel parking.

Breakdown:

• 평행 = parallel
• 주차 = parking

So together they form the noun parallel parking.

You may sometimes also see this written as 평행주차. The meaning is the same.

평행 주차를 = 평행 주차 + 를

The particle 를 marks 평행 주차 as the object of 연습합니다.

In other words, it answers the question:

• Practice what?
• Parallel parking.

Because the noun phrase ends in a vowel sound, it takes 를 rather than 을.

연습합니다 is the formal polite present-style form of 연습하다 (to practice).

So:

• dictionary form: 연습하다
• formal polite: 연습합니다

This style is very common in:

• instructions
• announcements
• manuals
• formal writing
• classroom examples

It sounds neat, official, and polite.

Grammatically, yes, it is in the present-style form, but in Korean this form can express more than just right now.

Depending on context, it can mean:

• a habitual action: (someone) practices
• a general instruction: practice
• a step in a procedure: check the lane and practice parallel parking

So in a learning or instructional context, this sentence may sound a bit like:

• Check the lane and practice parallel parking.

Even though the verb is not an English-style imperative, it can still function instructionally.

Both 확인하다 and 연습하다 are very common 하다 verbs, built from nouns of Sino-Korean origin.

• 확인하다 = to confirm/check
• 연습하다 = to practice

Korean uses these kinds of verbs very often, especially in formal, educational, or instructional language.

A learner should get used to this pattern:

• noun + 하다 = verb

Examples:

• 공부하다 = to study
• 운전하다 = to drive
• 주차하다 = to park
• 연습하다 = to practice

Yes. A less formal polite version would be:

• 차선을 확인하고 평행 주차를 연습해요.

An even more casual version could be:

• 차선을 확인하고 평행 주차를 연습해.

The meaning stays the same. The difference is mainly the level of politeness and formality.

• 연습합니다 = formal polite
• 연습해요 = standard polite
• 연습해 = casual

Yes, depending on nuance.

For example:

• 차선을 확인한 후 평행 주차를 연습합니다.

  • After checking the lane, practice parallel parking.
  • Slightly more explicit about sequence

• 차선을 확인해서 평행 주차를 연습합니다.

  • Can sound like check the lane and then practice or sometimes because you checked the lane...
  • The nuance depends on context

• 차선을 확인하며 평행 주차를 연습합니다.

  • Practice parallel parking while checking the lane
  • This changes the meaning, because it suggests simultaneous action

So -고 is a very neutral and natural connector here.

In careful spelling, it is 합-니-다, but in natural speech it is often pronounced closer to 함니다.

So:

• written: 합니다
• commonly heard: 함니다

This is a normal sound change in Korean pronunciation.

Similarly, the whole sentence may sound a bit smoother in real speech than it looks from the spelling.

It is mainly describing a sequence:

1. 차선을 확인하고 = check the lane
2. 평행 주차를 연습합니다 = practice parallel parking

But because the two actions are closely related, it can also feel like one combined training step in a driving lesson.

That is very common in Korean instructions: several linked actions are presented as one smooth procedure.
