Had laju di plaza tol itu rendah.

Had laju means speed limit.

• had = limit
• laju = speed / fast

Together, they form a common fixed expression: had laju = speed limit.

Malay often leaves out the verb to be when an adjective is the predicate.

So:

• Had laju di plaza tol itu rendah.

literally works like:

• The speed limit at that toll plaza low.

But in natural English, we say:

• The speed limit at that toll plaza is low.

This is very normal in Malay. You do not need is in sentences like this.

Di is a preposition meaning at, in, or on, depending on context.

In this sentence:

• di plaza tol itu = at that toll plaza

It tells you the location connected with the speed limit.

Itu means that.

In Malay, demonstratives like ini and itu usually come after the noun, not before it.

So:

• plaza tol itu = that toll plaza
• not that plaza tol

This word order is completely normal in Malay.

Yes, plaza tol is a normal and natural expression.

• plaza = plaza
• tol = toll

So plaza tol refers to the toll plaza area, not just one individual toll booth.

Because rendah is the main predicate of the sentence.

The sentence structure is:

• Had laju di plaza tol itu = the subject
• rendah = low

So the full meaning is:

• The speed limit at that toll plaza is low.

It comes at the end because it is saying something about the subject.

Yes. Rendah means low, and it can be used for things like levels, amounts, prices, and limits.

So a speed limit can be:

• rendah = low
• tinggi = high

That is natural Malay.

Because that would mean something slightly different in structure.

• Had laju di plaza tol itu rendah.
  = The speed limit at that toll plaza is low.

• had laju yang rendah
  = a low speed limit / the speed limit that is low

So:

• rendah by itself at the end = predicate adjective
• yang rendah after the noun = adjective phrase modifying the noun directly

Both are possible, but they do different jobs.

It describes where that speed limit applies.

So the meaning is:

• the speed limit at that toll plaza

not:

• the speed limit is sitting there physically

Malay often uses location phrases like this very naturally to show where something exists or applies.

You could, but it sounds more formal or stiff, and in everyday Malay it is usually less natural here.

The simpler and more natural version is:

• Had laju di plaza tol itu rendah.

Malay often avoids adalah with adjective predicates in ordinary sentences.

Yes. Itu often points to something specific that both speaker and listener already know, or something mentioned earlier.

So plaza tol itu can mean:

• that toll plaza over there
• or that toll plaza we were talking about

Its exact force depends on context.

A helpful way to break it down is:

• Had laju = speed limit
• di plaza tol itu = at that toll plaza
• rendah = low

So the pattern is:

• Subject + location phrase + adjective

More fully:

• [Had laju di plaza tol itu] [rendah].

That is a very normal Malay sentence pattern.
