Gunakan lampu kecemasan sekiranya berlaku kerosakan kenderaan.

Yes. Gunakan is an instruction, so the sentence is giving an order or official guidance: Use the hazard lights if a vehicle breakdown occurs.

In Malay, public notices and safety instructions often start directly with the verb, without a subject like you. So:

• Gunakan ... = Use ...
• implied subject = you

This is very normal on signs, notices, manuals, and official instructions.

Guna means use and can function as a verb in everyday Malay.

Gunakan is formed from guna + -kan, and in this kind of sentence it sounds more suitable for formal instructions and notices.

Compare:

• Guna lampu kecemasan... = more casual speech
• Gunakan lampu kecemasan... = more standard/formal written instruction

So in this sentence, gunakan is the natural choice for a safety notice.

Literally:

• lampu = light/lamp
• kecemasan = emergency

So lampu kecemasan literally means emergency lights. In the context of a vehicle, it usually refers to hazard lights.

Malay often uses this kind of noun + noun combination, where the second word describes the first.

Malay usually puts the main noun first, followed by the word that describes or specifies it.

So:

• lampu kecemasan = emergency light(s)
• literally: light emergency

This is a very common Malay pattern:

• kereta polis = police car
• pintu belakang = back door
• lampu isyarat = traffic light / signal light

So the word order may feel reversed compared with English, but it is normal in Malay.

Sekiranya means if or in the event that.

It is similar to:

• jika = if
• kalau = if

But the tone is a bit different:

• kalau = common in speech, more casual
• jika = standard and neutral
• sekiranya = more formal, often used in writing, notices, announcements, and official language

So sekiranya fits the formal tone of this sentence very well.

Because the sentence is using a more formal, official style.

Breakdown:

• berlaku = happen / occur
• kerosakan = damage / malfunction / breakdown
• kenderaan = vehicle

So sekiranya berlaku kerosakan kenderaan means something like:

• if a vehicle breakdown occurs
• if there is vehicle damage/failure

A more everyday way to say something similar would be:

• jika kenderaan rosak = if the vehicle breaks down / if the vehicle is damaged

Both are understandable, but the original sentence sounds more formal and notice-like.

Berlaku means to happen or to occur.

In this sentence, it introduces the event:

• berlaku kerosakan kenderaan = a vehicle breakdown occurs

This is a common formal pattern in Malay:

• berlaku kemalangan = an accident occurs
• berlaku kebakaran = a fire occurs
• berlaku kerosakan = damage/failure occurs

So berlaku makes the sentence sound more official and impersonal.

Rosak is the basic word meaning broken, damaged, or not working.

Kerosakan is a noun formed from rosak, and it means:

• damage
• fault
• breakdown
• malfunction

So:

• kenderaan rosak = the vehicle is broken / damaged
• kerosakan kenderaan = vehicle damage / vehicle breakdown

In this sentence, the noun kerosakan is used because the structure is talking about the occurrence of a breakdown as an event.

Because Malay does not normally use articles like a, an, or the.

So Malay often leaves things more general, and English adds articles when translating.

For example:

• lampu kecemasan = the hazard lights / hazard lights
• kenderaan = the vehicle / a vehicle / vehicle

The exact English article depends on context. In a safety instruction, English often chooses the or just uses a bare plural, but Malay does not need to mark that.

Also, Malay often does not explicitly say your unless it is necessary.

Malay often omits the subject when it is obvious, especially in commands, notices, and instructions.

So instead of saying:

• Anda gunakan lampu kecemasan...

Malay normally just says:

• Gunakan lampu kecemasan...

This is exactly like English signs that say:

• Keep left
• Wear a seatbelt
• Do not enter

The you is understood.

Not exactly. Kenderaan means vehicle, so it is more general than car.

It can include:

• cars
• motorcycles
• vans
• lorries/trucks
• buses

In context, if the notice is aimed at drivers, English may sometimes translate it more naturally with vehicle or occasionally car, but the Malay word itself is broader.

Yes, absolutely.

That version means the same thing:

• Sekiranya berlaku kerosakan kenderaan, gunakan lampu kecemasan.
• Gunakan lampu kecemasan sekiranya berlaku kerosakan kenderaan.

Malay allows this kind of clause movement quite easily, especially with condition words like jika, kalau, and sekiranya.

The difference is mostly about emphasis:

• starting with Gunakan... emphasizes the instruction
• starting with Sekiranya... emphasizes the condition

It is natural, but definitely on the formal side.

It sounds like something you would see in:

• road safety materials
• manuals
• official notices
• test questions
• public information signs

A more conversational version might be:

• Kalau kenderaan rosak, guna lampu kecemasan.

That means the same basic thing, but it is less formal and more speech-like.

A useful way is:

• Gunakan = use
• lampu kecemasan = hazard lights / emergency lights
• sekiranya = if / in the event that
• berlaku = occurs / happens
• kerosakan kenderaan = vehicle breakdown / vehicle damage

So the structure is:

• [Instruction] + [thing to use] + [condition]

That can help you read many similar Malay safety sentences more easily.
