La voiture va tout droit.

Va is the third-person singular present-tense form of the verb aller, which means to go.

The subject here is la voiture = the car, and the car is a third-person singular subject, so French uses va:

• je vais = I go / I am going
• tu vas = you go / you are going
• il / elle / on va = he / she / it / one goes / is going

So:

• La voiture va ... = The car goes / is going ...

Tout droit is an adverbial expression meaning straight, straight ahead, or directly ahead.

So in La voiture va tout droit, it describes how or in what direction the car is going.

You can think of it as similar to:

• go straight
• drive straight ahead

It is a very common French expression.

Yes, droit can mean straight, but tout droit is a very common set phrase meaning straight ahead or directly straight.

Here, tout adds emphasis or completeness, a bit like:

• straight on
• right straight ahead

In many everyday contexts, French prefers tout droit rather than just droit when talking about movement or direction.

So:

• aller tout droit = to go straight ahead

This is something learners usually just memorize as a fixed expression.

La is the definite article meaning the.

French uses articles more consistently than English does. In this sentence, la voiture simply means the car.

Also, because voiture is a feminine singular noun, the article is la:

• le for masculine singular
• la for feminine singular
• les for plural

So:

• la voiture = the car

In French, expressions that describe direction often come after the verb.

So the structure is:

• La voiture = subject
• va = verb
• tout droit = adverbial expression of direction

This word order is very natural in French:

• Il va vite = He goes fast / He is going fast
• Elle marche lentement = She walks slowly
• La voiture va tout droit = The car goes straight ahead

For an English speaker, this feels fairly familiar, because English also often puts this kind of information after the verb.

Yes, very much so.

Aller tout droit is a common expression used for:

• physical movement: go straight ahead
• directions: continue straight
• sometimes figurative use: go directly toward something

Examples:

• Continuez tout droit. = Continue straight ahead.
• Va tout droit au carrefour. = Go straight at the crossroads.

So in your sentence, va tout droit is a very normal combination.

Yes.

The French present tense often covers both meanings that English separates into:

• The car goes straight
• The car is going straight

French va can express either:

• a general present
• an action happening now

Usually the context tells you which one is meant.

A careful approximate pronunciation is:

la vwa-tyur va too drwah

A few useful points:

• voiture is roughly vwa-tyur
• va sounds like va
• in tout, the final t is normally silent
• droit sounds roughly like drwah

Also, there is normally no strong pause between the words. French flows smoothly:

La voiture va tout droit.

You may hear aller droit in some contexts, but aller tout droit is the more standard and common everyday expression for go straight ahead.

For a learner, the safest and most natural choice is:

• aller tout droit

So if you want to say The car goes straight ahead, La voiture va tout droit is an excellent sentence to learn.

French often uses aller = to go where English might use go, drive, or even head depending on context.

Because the subject is la voiture, it is already clear that the movement is being done by a car, so va sounds natural.

French does not need to say drives unless that specific idea is important. The sentence simply describes the car’s movement:

• La voiture va tout droit = The car goes / is going straight ahead

So this is idiomatic French, not a word-for-word match to every possible English version.
