Jangan nekat berkendara di jalan tol saat hujan deras.

Jangan is used to make a negative command, so it means don’t.

So Jangan nekat berkendara... means something like Don’t recklessly drive... or Don’t insist on driving...

A very common pattern in Indonesian is:

• Jangan + verb / adjective / phrase

Examples:

• Jangan pergi. = Don’t go.
• Jangan khawatir. = Don’t worry.
• Jangan nekat. = Don’t be reckless / Don’t push it.

In Indonesian, commands often leave out the subject because it is understood from context.

So instead of saying:

• Jangan Anda nekat berkendara...
• Jangan kamu nekat berkendara...

it is much more natural to simply say:

• Jangan nekat berkendara...

English does the same thing:

• Don’t drive... not usually
• You don’t drive...

If you do add a subject in Indonesian, it can sound more specific, emphatic, or less natural depending on the context.

Nekat means doing something bold, reckless, or stubbornly despite danger, risk, or common sense.

In this sentence, it suggests:

• driving even though conditions are dangerous
• taking an unnecessary risk
• pushing ahead when you really should not

So jangan nekat is stronger than just don’t. It carries the idea:

• Don’t be reckless
• Don’t force it
• Don’t take that risk

Here, nekat describes the manner or attitude of the action. It tells you how someone is driving: recklessly, rashly, irresponsibly.

So:

• nekat berkendara = to drive recklessly / to insist on driving despite danger

Indonesian often puts this kind of descriptive word before the verb phrase.

You can think of it as:

• Don’t be reckless about driving
• Don’t recklessly drive

Berkendara means to operate a vehicle, to travel by vehicle, or more simply to drive/ride.

It is a fairly general and somewhat formal word. It can refer to using a vehicle, not only specifically a car.

Mengemudi is closer to to drive in the sense of controlling a car or vehicle.

So:

• berkendara = travel/drive/ride in a vehicle, somewhat broader
• mengemudi = drive a vehicle, more specifically the act of driving

In this sentence, berkendara works well because it sounds like a public safety warning.

The prefix ber- often forms intransitive verbs, often with meanings like:

• to do something
• to have/use something
• to engage in an activity

In berkendara, it turns kendara-related vocabulary into a verb meaning to travel/drive/use a vehicle.

As a learner, you do not always need to analyze every ber- word mechanically, because many are best learned as whole vocabulary items. But it is useful to recognize that ber- often creates verbs for activities.

Other examples:

• berjalan = to walk
• berbicara = to speak
• berenang = to swim

Good question. Indonesian has two different di forms:

• di as a preposition = in, on, at → written separately
• di- as a passive prefix → written attached

Here, di jalan tol means on the toll road, so di is a preposition and must be written separately.

Compare:

• di jalan tol = on the toll road
• ditutup = closed, was closed, is closed

This spelling distinction is very important in Indonesian.

Jalan tol means toll road. Depending on context, in English it may be translated as:

• toll road
• expressway
• highway
• freeway sometimes, if that sounds more natural in the translation

Word by word:

• jalan = road
• tol = toll

So di jalan tol means on the toll road / on the expressway.

Saat means when or during.

So:

• saat hujan deras = when it is raining heavily / during heavy rain

Yes, saat, ketika, and sometimes waktu can overlap.

For example:

• saat hujan deras
• ketika hujan deras

Both are natural.

In this sentence, saat sounds clear and standard, especially in formal or informational language.

Because deras comes after the noun hujan to describe it.

So:

• hujan deras = heavy rain

This is the normal Indonesian order:

• noun + descriptive word

Other examples:

• rumah besar = big house
• air panas = hot water
• angin kencang = strong wind

So hujan deras is the natural order.

Yes. Hujan means rain, and deras means heavy in the sense of something falling or flowing strongly.

So:

• hujan deras = heavy rain

You would also see:

• hujan lebat = heavy rain

Both are common, though deras often emphasizes the force or intensity of rain.

A simple way to break it down is:

• Jangan = don’t
• nekat = recklessly / rashly / stubbornly despite danger
• berkendara = drive / operate a vehicle
• di jalan tol = on the toll road
• saat hujan deras = during heavy rain / when it is raining heavily

So the structure is roughly:

• negative command
• manner/attitude
• action
• location
• time/condition

That makes the sentence feel like a warning or public safety advice.

It sounds like a warning or public safety message. It is natural in:

• road safety campaigns
• announcements
• news-style writing
• official advice

The word nekat adds a slightly strong, cautionary tone, while berkendara sounds fairly standard or formal.

A more casual version might use different wording, but this sentence is very natural for a warning sign or advisory message.

Yes. Here are some natural alternatives with slightly different nuance:

• Jangan berkendara di jalan tol saat hujan deras.
  A simpler warning: Don’t drive on the toll road during heavy rain.

• Jangan memaksakan diri berkendara di jalan tol saat hujan deras.
  More like: Don’t force yourself to drive on the toll road during heavy rain.

• Hindari berkendara di jalan tol saat hujan deras.
  Avoid driving on the toll road during heavy rain.

The original sentence with nekat especially emphasizes the danger and recklessness of doing it anyway.
