Если на дороге не будет пробки, мы доедем до вокзала вовремя.

Because the sentence is talking about the future: If there isn’t a traffic jam on the road, we will get to the station on time.

• нет means there is no / there isn’t right now.
• не будет means there will not be.

So:

• На дороге нет пробки = There is no traffic jam on the road.
• На дороге не будет пробки = There will not be a traffic jam on the road.

Russian does not follow the English pattern of using a present form after if for future meaning. In Russian, future meaning is usually shown directly with the future tense: если ... не будет ...

Because after не будет in this kind of there will not be construction, Russian commonly uses the genitive case.

So:

• будет пробка = there will be a traffic jam
• не будет пробки = there will not be a traffic jam

This is a very common pattern with быть under negation:

• будет время → не будет времени
• будет проблема → не будет проблемы
• будет пробка → не будет пробки

So пробки here is genitive singular.

Here пробка means traffic jam.

This word has several meanings in Russian, just like in English some words have more than one meaning. Depending on context, пробка can also mean:

• a cork
• a stopper
• a traffic jam

In this sentence, because we have на дороге and are talking about getting somewhere on time, the meaning is clearly traffic jam.

На дороге means on the road or on the route.

It uses the preposition на plus the prepositional case:

• дорога → на дороге

This phrase can refer to the road itself, or more generally to the traffic situation on the way. In this sentence, Если на дороге не будет пробки means something like:

• If there’s no traffic jam on the road
• If the road isn’t jammed
• If traffic is clear on the way

Because Russian uses a comma to separate the if-clause from the main clause.

So:

• Если на дороге не будет пробки, мы доедем до вокзала вовремя.

This is standard Russian punctuation. When a sentence begins with если (if), the subordinate clause is usually followed by a comma before the main clause.

Доедем is the 1st person plural future form of доехать, which means to get as far as / to reach a destination by transport.

So мы доедем means:

• we will get there
• we will make it
• we will reach it by vehicle

The verb is built from ехать (to go by vehicle) with the prefix до-, which adds the idea of reaching the destination.

Compare:

• ехать = to be going by vehicle
• доехать = to get to / reach by vehicle

In this sentence, доедем is perfective future, so it expresses a completed result: we will arrive/reach the station.

Because the verb доехать normally goes with до + genitive to express the destination reached.

So:

• доехать до вокзала = to get to the station / to reach the station

This is simply the standard pattern:

• доехать до дома = get home
• доехать до центра = get to the center
• доехать до вокзала = get to the station

Other prepositions mean different things:

• к вокзалу = toward the station / up to the station
• на вокзал = to the station, often with verbs like идти, ехать, поехать

For example:

• Мы едем на вокзал. = We are going to the station.
• Мы доедем до вокзала. = We will get to the station.

It is genitive singular.

The dictionary form is вокзал. After the preposition до, Russian uses the genitive case:

• вокзал → до вокзала

This happens because до always takes the genitive:

• до дома
• до города
• до вокзала

Because вовремя is an adverb meaning on time.

• вовремя = on time / in time

This is different from во время as two words:

• во время урока = during the lesson
• во время поездки = during the trip

So:

• Мы доедем вовремя = We’ll get there on time.
• Во время поездки было тихо = During the trip, it was quiet.

A very common learner mistake is to write во время when the meaning is on time. In this sentence, the correct form is the one-word adverb вовремя.

Not strictly. Russian often drops subject pronouns when the verb form already makes the subject clear.

So both are possible:

• Если на дороге не будет пробки, мы доедем до вокзала вовремя.
• Если на дороге не будет пробки, доедем до вокзала вовремя.

Because доедем already means we will get there, the pronoun мы is optional.

Including мы can make the sentence a little clearer, more explicit, or slightly more contrastive.

Yes, Russian word order is flexible, although some versions sound more natural than others.

The given sentence is neutral and natural:

• Если на дороге не будет пробки, мы доедем до вокзала вовремя.

You could also say:

• Мы доедем до вокзала вовремя, если на дороге не будет пробки.

That means the same thing: We’ll get to the station on time if there’s no traffic jam on the road.

Russian word order often changes for emphasis, information structure, or style, not basic meaning.

This is a very common question for English speakers.

In English, after if, we usually use the present form for future meaning:

• If there is no traffic jam, we will get there on time.

In Russian, that restriction does not exist in the same way. If the meaning is future, Russian normally uses the future:

• Если ... не будет ..., мы доедем ...

So this is perfectly normal Russian grammar. You should not try to copy the English tense pattern too closely here.

Yes, but пробка is the most common everyday word for a traffic jam.

• пробка = traffic jam, very common in speech
• затор = traffic congestion, traffic jam; a bit more formal or descriptive in some contexts

So:

• Если на дороге не будет пробки... sounds very natural in everyday Russian.

A sentence with затор would also be understandable, but пробка is probably the first word most learners should remember.
