The Train Driver
ATAVT Test
A complex traffic scene flashes for one second. You identify what you saw. Here is exactly what is being tested, what assessors look for, and how to get faster before your OPC.
What is the ATAVT test?
The ATAVT (Apparatus Test for Attentive and Vigilant Traffic perception) is a standardised psychometric test used in transport industry selection across Europe. In UK train driver OPC assessments, it forms a key part of the cognitive battery alongside the Vigilance Test, Group Bourdon, and TRP1. It measures perceptual speed and visual scene processing — how quickly and completely your brain can extract information from a complex visual environment in a very short exposure.
The test works as follows: a photograph of a real road traffic scene is displayed on screen for approximately one second, then removed. You are then shown a checklist of possible elements and asked to identify which ones were present in the scene — traffic lights and their state (red, amber, green), cars and larger vehicles such as lorries or buses, pedestrians, road signs, bicycles, and motorcycles. You work through 20 scenes in a session.
The challenge lies in the combination of a short exposure time, a complex image, and multiple independent elements to identify. There is no second chance to view the scene. Candidates who do well are those who have trained themselves to distribute their attention broadly across the full image rather than fixating on any single element.
For train drivers, this maps directly to the demands of the job. A driver approaching a busy level crossing, a platform with people near the edge, or a complex signals gantry must process a large amount of visual information very quickly and accurately. The ATAVT tests exactly this capacity in a standardised, measurable way.
How to prepare
Step by step
Learn the six element categories before your first practice run
Before you sit your first session, memorise the categories you will be asked about: traffic lights and their state, cars and larger vehicles, pedestrians, signs, bicycles, motorcycles. Knowing what to look for lets you use the one-second flash productively.
Use broad attention rather than focusing on one part of the scene
The most common mistake is fixating on the centre of the image. Train yourself to take in the whole scene with a soft, wide gaze — the same peripheral awareness that lets a driver spot a pedestrian stepping off a kerb at the edge of their vision.
Do not second-guess what you saw
Answer based on your first clear impression. Spending too long deliberating leads to lower overall accuracy because you are burning response time on one element at the expense of others.
Build a mental checklist to run during the flash
With practice, you can develop a rapid internal scan order — for example: lights → vehicles → people → signs — that ensures you sweep the whole scene in the available time rather than landing randomly.
Complete at least five full 20-scene sessions before your assessment
Perceptual speed improves with repetition. Five sessions exposes you to 100 scenes and gives your visual processing system the repeated exposure it needs to get faster and more accurate.
Review your accuracy by element after each session
If you consistently miss one category — say, motorcycles or background signs — focus your attention there in subsequent sessions. Per-element scoring lets you identify and fix specific weak points.
What you're identifying

Pedestrians
People on foot, crossing or at the roadside
Road signs
Warning, regulatory, or informational signs
Bicycles
Cyclists on road or pavement
Motorcycles
Motorbikes and scooters — easy to miss
FAQ
Common questions about the ATAVT
What does ATAVT stand for?
ATAVT stands for Apparatus Test for Attentive and Vigilant Traffic perception. It was developed in Germany and is used across European transport industries, including UK train driver selection, to measure how quickly and accurately candidates can process a complex visual scene.
How long does each scene flash on screen?
Each traffic scene is displayed for approximately one second before disappearing. You then have a short window to record which elements you observed. The brevity is intentional — the test measures perceptual speed, not memory recall over a long viewing period.
What elements do I need to identify in each scene?
You are typically asked about six categories: traffic lights (and their state — red, amber, or green), cars and larger vehicles, pedestrians, road signs, bicycles, and motorcycles. Each category is scored independently, so missing one element does not affect your score on the others.
Can I improve my ATAVT score through practice?
Yes — significantly. The main skill being tested is the ability to rapidly distribute attention across a complex scene without fixating on one part of it. This can be trained. Regular practice with realistic traffic scenes measurably improves how much you catch in a short flash.
Is the ATAVT used at all UK train operators?
The ATAVT is part of the standard OPC battery recommended by RSSB standard RIS-3751-TOM, which most UK train operating companies follow. The exact combination of tests may vary slightly by operator, but the ATAVT appears in the majority of OPC assessments.
What score do I need to pass the ATAVT?
Operators do not typically publish minimum pass scores publicly. The assessment is used as part of a holistic profile alongside other OPC tests and an interview. Performing consistently across all elements — rather than excelling on some and failing on others — is the most reliable approach.
