Эвакуатор ждал рядом на случай, если штрафстоянка снова откроется.

Here эвакуатор means a tow truck.

In Russian, эвакуатор is the normal word for the vehicle that carries away broken-down or illegally parked cars. The word is related to эвакуация, but in everyday usage it very often specifically means tow truck.

Ждал is the masculine singular past tense form of ждать (to wait).

Russian past tense agrees with the subject in gender and number:

• он ждал = he waited
• она ждала = she waited
• оно ждало = it waited
• они ждали = they waited

Since эвакуатор is a masculine singular noun, the verb becomes ждал.

The verb ждать here is imperfective because it describes an ongoing state or process: the tow truck was waiting / waited around.

Imperfective is natural when the focus is on the situation itself, not on a completed result. A tow truck does not usually complete a single action of waiting in the same way it might arrive or leave; instead, it is simply in the state of waiting.

So ждал fits the idea of:

• being there
• remaining nearby
• waiting in readiness

Рядом means nearby, close by, or next to it depending on context.

In this sentence, it stands on its own as an adverb:

• ждал рядом = waited nearby

Russian often allows рядом without explicitly saying with what or near what, if the context already makes that clear.

You can also use it with с + instrumental:

• рядом с домом = next to the house
• рядом с штрафстоянкой = near the impound lot

But here the speaker simply says the tow truck was nearby, and that is enough.

На случай means in case of or, in this pattern, simply in case.

The common structure is:

• на случай, если ... = in case ...

So:

• на случай, если штрафстоянка снова откроется = in case the impound lot opens again

This is a very common Russian expression.

Examples:

• Возьми зонт на случай, если пойдёт дождь. = Take an umbrella in case it rains.
• Я записал адрес на случай, если заблужусь. = I wrote down the address in case I get lost.

It may feel a little repetitive from an English-speaking perspective, but in Russian this is a normal fixed pattern:

• на случай, если ...

Literally it looks like:

• for the case, if ...

But idiomatically it simply means:

• in case ...

So yes, both parts belong together very naturally in Russian. You should think of it as one set expression rather than as unnecessary duplication.

Because Russian normally uses the future after если when talking about a real possible future event.

So Russian says:

• если штрафстоянка снова откроется
  literally: if the impound lot opens again

English usually prefers the present form after if:

• if the impound lot opens again

But Russian does not avoid the future here. Using future after если is completely normal.

Откроется is the perfective future of открыться.

That form is used because the sentence refers to a single completed event in the future: the impound lot reopens / opens again.

Compare:

• открывается = is opening / opens regularly / is in the process of opening
• откроется = will open, will become open (one complete event)

Here the idea is not a repeated habit or ongoing process. It is one possible event:

• maybe it will reopen
• maybe it won’t

So откроется is the natural choice.

Because открыться means to open in the sense of become open, while открыть means to open something.

Compare:

• Охранник откроет штрафстоянку. = The guard will open the impound lot.
• Штрафстоянка откроется. = The impound lot will open.

So the reflexive form is used because the lot itself is the grammatical subject, and the meaning is become open / reopen rather than open something else.

Штрафстоянка is in the nominative case because it is the subject of откроется.

The structure is:

• штрафстоянка = the impound lot
• откроется = will open

So штрафстоянка is the thing doing the action grammatically.

Штрафстоянка is an impound lot, especially a place where cars are taken after being towed for parking or legal violations.

It is made from:

• штраф = fine, penalty
• стоянка = parking area, parking lot

So the word gives the idea of a penalty parking lot or impound lot.

Because если штрафстоянка снова откроется is a subordinate clause.

Russian punctuation normally separates the main clause from a subordinate clause with a comma:

• Эвакуатор ждал рядом, ...
• ..., если штрафстоянка снова откроется.

Since the sentence also includes на случай, the comma still appears before если:

• на случай, если ...

This is standard Russian punctuation.

Снова means again.

Yes, опять could often be used in a similar sentence, but there is a nuance:

• снова is often a bit more neutral
• опять can sometimes sound more emotional, like again! or yet again

So in a neutral narrative sentence like this, снова sounds very natural.

Yes. Russian word order is fairly flexible.

This version:

• Эвакуатор ждал рядом на случай, если штрафстоянка снова откроется.

is natural and straightforward:

1. subject: эвакуатор
2. verb: ждал
3. place: рядом
4. purpose/precaution: на случай, если...

Other orders are possible for emphasis, for example:

• Рядом ждал эвакуатор на случай, если штрафстоянка снова откроется.
• На случай, если штрафстоянка снова откроется, рядом ждал эвакуатор.

These alternatives shift emphasis, but the original order is very natural in ordinary narration.

Usually was waiting nearby is the best match in feel.

Russian past imperfective ждал often corresponds to:

• was waiting
• waited
• had been waiting

depending on context.

Here the sense is very much of an ongoing situation in the background, so was waiting nearby captures it well.

Yes, it expresses a kind of precautionary purpose.

The tow truck was nearby as a precaution or just in case the impound lot reopened.

So the sentence is not only saying where the tow truck was, but also why it was there. It was positioned there in preparation for a possible event.

You could translate it literally that way, but more natural English would usually be:

• The tow truck was waiting nearby in case the impound lot reopened.
• The tow truck waited nearby in case the impound lot opened again.

English often adjusts the tense to sound smoother, while Russian keeps the future откроется inside the если clause. So the Russian grammar is normal even if a word-for-word English version sounds slightly odd.
