Фотофиксация показала регистрационный знак и правонарушение.

Фотофиксация is a formal word meaning something like photographic recording, camera capture, or photo evidence.

In this sentence, it refers to the fact that a camera image or photo record documented something. In traffic-related contexts, it often means an automatic camera recorded the violation.

It is built from:

• фото- = photo
• фиксация = fixing, recording, documenting

So the idea is not just a photo, but a documented photographic record.

Because фотофиксация is a feminine noun in Russian.

• фотофиксация → feminine
• past tense verb must agree with it in gender
• so: показала

Compare:

• снимок показал = the photo showed
• камера показала = the camera showed
• фотофиксация показала = the photographic record showed

In the past tense, Russian verbs change for gender in the singular:

• masculine: показал
• feminine: показала
• neuter: показало

They are in the accusative case, because they are the direct objects of показала.

The verb показать means to show, and what is shown goes into the accusative.

So:

• показала что? → регистрационный знак и правонарушение

However, these forms look the same as the nominative here:

• регистрационный знак is masculine inanimate, so nominative and accusative are the same
• правонарушение is neuter, and nominative and accusative are also the same

That is why they look like dictionary forms.

Yes. Регистрационный знак is a formal or official way to say registration plate or license plate.

Word by word:

• регистрационный = registration
• знак = sign, mark

In everyday speech, Russians often say:

• номер
• номер машины
• номерной знак

But регистрационный знак is common in official, legal, or bureaucratic language.

Russian does not have articles like a/an and the.

So:

• регистрационный знак can mean a registration plate or the registration plate
• правонарушение can mean a violation or the violation

The exact meaning depends on context. In a sentence like this, English often uses the because the plate and the offense are specific in context, but Russian does not need a separate word for that.

Правонарушение means offense, violation, or legal infraction.

It is a formal legal word. In a traffic context, it usually means a traffic violation.

It is made up of:

• право = law, right
• нарушение = violation, breaking

So literally it is something like a violation of the law.

This is much more formal than casual speech. In everyday conversation, someone might simply say something more specific, depending on the situation.

Регистрационный is an adjective modifying знак, and it has to agree with знак in gender, number, and case.

• знак is masculine singular
• accusative singular of an inanimate masculine noun looks like nominative
• so the adjective is регистрационный

In the same sentence, правонарушение stands by itself without an adjective, so there is no matching adjective to notice there.

If you added one, it would have to agree with the neuter noun:

• серьёзное правонарушение = a serious offense

Yes, Russian word order is flexible.

This sentence uses a straightforward neutral order:

• subject → verb → objects

So:

• Фотофиксация = subject
• показала = verb
• регистрационный знак и правонарушение = objects

You could change the order for emphasis, for example:

• Регистрационный знак и правонарушение показала фотофиксация.

That still means roughly the same thing, but it sounds more marked and puts more focus on what was shown.

For a learner, the original order is the easiest and most neutral to understand.

Показала is the past tense of the perfective verb показать.

Perfective usually presents an action as a completed whole:

• показала = showed, revealed, demonstrated

If you used the imperfective показывала, it would suggest something more ongoing, repeated, or descriptive:

• показывала = was showing, used to show

In this sentence, the idea is that the photographic record successfully captured and showed the plate and the offense as a completed fact, so показала is the natural choice.

Yes.

The conjunction и means and, and here it connects two things that the photographic record showed:

• регистрационный знак
• правонарушение

Both are objects of показала, so both are understood in the accusative.

Russian often does this just like English:

• показала знак и правонарушение = showed the plate and the violation

It sounds fairly official, bureaucratic, or legal.

The words фотофиксация, регистрационный знак, and правонарушение are all somewhat formal. This kind of sentence fits well in:

• police reports
• legal documents
• traffic camera notices
• administrative writing

In everyday speech, people might use simpler wording, such as talking about a camera, a photo, a plate number, or a traffic violation in less formal terms. But for official Russian, this sentence sounds natural.
