Esta estación de ITV realiza inspecciones técnicas de vehículos.

Because estación is a feminine noun in Spanish, even though it ends in -ón.

So the demonstrative has to agree with it:

• esta estación = this station
• esa estación = that station

A lot of nouns ending in -ción or -sión are feminine:

• la estación
• la inspección
• la revisión

In Spain, ITV stands for Inspección Técnica de Vehículos.

It is the official vehicle inspection, similar to an MOT in the UK. In everyday Spanish, people often just say:

• pasar la ITV = to pass / go through the vehicle inspection
• la estación de ITV = the vehicle inspection station

Even though the full expression is longer, the acronym ITV is extremely common and widely understood in Spain.

Here de means something like for or of, depending on how you want to think about it.

• estación de ITV = ITV station / vehicle inspection station

Spanish often uses de where English uses a noun before another noun:

• centro de salud = health centre
• tarjeta de crédito = credit card
• estación de tren = train station

So de ITV tells you what kind of station it is.

Realizar is a more formal and administrative-sounding verb here. It means to carry out or to perform.

So:

• realiza inspecciones = carries out inspections

You could understand it as more official than hacer. In this kind of context, Spanish often prefers:

• realizar un trámite
• realizar una prueba
• realizar una inspección

It sounds natural in notices, websites, and formal descriptions of services.

Because the subject is esta estación de ITV, which is singular.

The main noun is estación, so the verb must match that singular noun:

• Esta estación ... realiza ...

Even though inspecciones and vehículos are plural, they are not the subject. They are what the station performs.

Because the sentence is describing what the station does in general.

• realiza inspecciones técnicas de vehículos = it carries out vehicle technical inspections

The plural gives a general meaning: this station performs these inspections as a service, for many vehicles, not just one specific inspection.

If it were singular, realiza una inspección técnica de vehículos, it would sound more like talking about one inspection in particular.

Because técnicas is an adjective describing inspecciones, and adjectives in Spanish must agree with the noun in gender and number.

Here:

• inspecciones is feminine plural
• so the adjective must also be feminine plural
• therefore: técnicas

Compare:

• inspección técnica = singular
• inspecciones técnicas = plural

It tells you what the inspections are inspections of.

So:

• inspecciones técnicas de vehículos = technical inspections of vehicles

This is a very common Spanish structure:

• análisis de sangre = blood test
• reparación de coches = repair of cars
• control de calidad = quality control

In English, we often turn this into a noun modifier:

• vehicle inspections rather than
• inspections of vehicles

But in Spanish, de is the normal way to express that relationship.

Because in this structure, Spanish often leaves out the article after de when the second noun works like a category or label.

So:

• estación de ITV sounds natural
• it means an ITV station or a vehicle inspection station

Spanish frequently does this with types of places or services:

• clase de inglés
• carné de conducir
• centro de salud

You may sometimes hear articles with acronyms in other contexts, but here the article is normally omitted.

Because de vehículos is being used in a general, classifying way.

It means the inspections are for vehicles in general, not for some specific vehicles already known in the conversation.

Compare:

• inspecciones técnicas de vehículos = vehicle technical inspections / inspections of vehicles in general
• inspecciones técnicas de los vehículos = inspections of the vehicles, meaning some specific vehicles

So the absence of los makes the phrase more general and standard.

In Spain, estación de ITV is the normal fixed expression. It refers to the place where the inspection is carried out.

You might also see words like centro or instalación in some contexts, but estación de ITV is very common and idiomatic.

So for this specific Spanish service, estación de ITV is the natural phrase to learn.

In Spain, it is usually pronounced letter by letter:

• i te uve

That is how acronyms are often read when they are not pronounced as a single word.

So if you hear someone say la ITV, they are typically saying the names of the letters, not trying to pronounce it as one word.

Grammatically, yes, but it sounds less formal and less natural for this kind of official description.

• realiza inspecciones = more formal, institutional, professional
• hace inspecciones = understandable, but less polished in this context

For a company website, sign, or official description, realiza is the better choice.
