Buying a used car always comes with risks, and the most critical of them is purchasing a vehicle with an accident history. Hidden body defects, broken beam geometry, or improperly repaired electronics can cause a serious accident in the future. That is why checking road accidents by car number is a mandatory stage of pre-sale preparation, which cannot be ignored under any circumstances.
Modern digital services allow you to obtain detailed information about a car’s past without leaving your home. However, the abundance of data sources often confuses the buyer: some resources show a clean history, others show many records of damage. Only a systematic approach to data analysis will help you understand what information you can trust and how to correctly interpret dry numbers and damage codes.
Official traffic police database: capabilities and limitations
The main and most reliable source of information about road accidents is the official website of the traffic police. Data on all accidents recorded by police officers with the participation of inspectors is stored here. To obtain information you will need to enter state registration number, body or chassis number, as well as the number of the vehicle registration certificate (VRC). It is important to understand that access to the full report is possible only if you have STS data, which can be obtained from the seller or seen in photographs in the ad.
The site's interface is quite simple, but the results may not be obvious to an untrained user. The system will display a list of all registered road accidents, indicating the date, type of incident and a schematic location of the damage. However, there is an important nuance here: if the accident was registered according to the European protocol without calling the police, it may not be displayed in the traffic police database, or it may appear there with a significant delay.
In addition, on the site you can often find the status “Verification not found” or “Data not found,” which does not always mean a crystal clear history. Sometimes this indicates technical errors when entering data by the inspector or that the car was registered in another state until a certain point. Therefore rely solely on one source state traffic inspectors not worth it.
⚠️ Attention: The absence of records in the traffic police database does not guarantee that the car was not involved in an accident. Drivers file many minor accidents either through insurance companies without involving the police, and this data does not always quickly enter the general database.
Why may there be no data in the traffic police?
There may be no record of an accident for several reasons: the accident was registered according to the European protocol and the data has not yet been transferred, the car was involved in an accident before 2015 (digitalization period), or the car was stolen and found in another region with altered documents. It is also possible that the damage was recorded by the insurance agent, but a police report was not filed.
Commercial aggregators: is it worth paying for a report?
Unlike free government resources, commercial services collect information from many sources, including databases of insurance companies, maintenance services, banks and private advertisements. Checking a car by license plate number through platforms such as Autocode, ProAuto or Autotek, allows you to see a much more complete picture. The paid report often contains photographs from accident scenes, calculations of repair work, and even mileage recorded during the last maintenance.
The main advantage of such services is data aggregation. While you manually check the car against the databases of search, collateral and restrictions, the algorithms will collect everything into a single chronological list. This is especially useful for identifying misaligned mileage: if in 2018, when changing the oil, the mileage was 150,000 km, and in 2023 the seller claims 120,000 km, the system will automatically highlight this discrepancy.
However, here too there are pitfalls. Data arrives in commercial databases with a delay, and some small services may not transmit information to general registries. Additionally, the cost per report can be high if you plan to look at many options. It is often more profitable to buy a package of checks or use the free limits that some sites provide when posting an advertisement for sale.
Analysis of photographs and nature of damage
The most valuable part of any accident report is the photographs. It is a visual assessment that allows us to understand the real scale of the tragedy, which dry numbers “bumper repair” or “headlight replacement” cannot convey. When analyzing images, pay attention to the nature of deformation of adjacent elements. If the description indicates damage to the wing, and the photo shows that the door and body pillar are crushed, it means that the impact was much stronger than officially stated.
Particular attention should be paid to photographs taken immediately after evacuation or at the scene of the incident. They often show spilled technical fluids and the condition of the wheels and suspension. If the photo shows that the wheel is turned at an unnatural angle or damage to the elements is visible chassis, this is a direct signal of a serious blow to the suspension, which threatens costly repairs in the future.
It is also important to compare the date of the accident and the date of sale of the car. If the car was in an accident a month ago, and today it is already put up for sale, this is an alarming sign. High-quality body repairs take from two weeks to several months, depending on the complexity. A quick sale often means that the repair was done in a hurry using cheap materials, or the car has hidden electronic problems that will appear later.
Save screenshots of all found accident photos immediately. Services may delete archived photos after some time, and you will still have an evidence base for bargaining or refusing to purchase.
Interpretation of data on repairs and insurance claims
Data from insurance companies (RSA, Casco) often reveal the true cost of restoring a car. The amount of payment or the cost of standard hours in the defect report gives an understanding of the depth of the damage. For example, a payment of 10,000 rubles most likely means replacing a bumper or headlight, while a bill of 300,000 rubles or more indicates serious body repairs involving power elements.
Reports often contain damage codes or their text descriptions. It is important to distinguish between the concepts of “repair” and “replacement”. Replacing an element with a new one is good, since the factory geometry is preserved. Repairs (straightening, puttying, painting) always involve the risk of violating the anti-corrosion protection and geometry. If the history includes multiple replacements of doors, hood or trunk lid, it is worth checking the gaps and the paint layer thickness gauge.
Records about total damage (Total Loss) deserve special attention. If the car was considered total by the insurance company, this means that the cost of its restoration exceeded the market value at the time of the accident. Buying such a car is a lottery, where the winning can only be external presentability, but the reality is constant breakdowns and safety problems.
| Record type | Probable Cause | Risk for the buyer |
|---|---|---|
| Minor bumper repairs | Parking incident, scratch | Minimal, cosmetics |
| Replacing headlight/glass | Stone hit, light contact | Low, check for leaks |
| Body repair (slipway) | Serious accident with geometry violation | High, possible sideways movement |
| Airbag replacement | Heavy impact, SRS activation | Critical, risk of incorrect operation of systems |
The amount of insurance compensation is the best indicator of the severity of an accident. If the payment exceeds 10-15% of the market value of the car, it is better to refrain from purchasing.
Hidden accidents and legal nuances
Not all accidents are officially recorded. Drivers can negotiate on the spot and leave, especially if the damage seems minor. However, six months later, the new owner may have a claim from the previous owner’s insurance company by way of subrogation if it turns out that the culprit fled the scene of the accident. Checking by phone number or VIN code through special applications sometimes helps to find information about such “popular” investigations.
Legal clarity also depends on how the car was restored. If, after a serious accident, the car was not officially deregistered for disposal or did not undergo proper examination, problems may arise when registering with the traffic police. The inspector has the right to refuse registration if he finds signs of poor-quality repairs of load-bearing structures or the presence of uncertified structural changes.
You should also be wary of cars that were stolen and found disassembled and then reassembled from different parts. In the traffic police database they may be listed as “found”, but upon detailed inspection and verification of unit numbers, inconsistencies may be revealed. Always check the VIN code on the body, engine and documents, paying attention to signs of tampering with the markings.
⚠️ Attention: If during inspection you find traces of welding on the side members or overcooked body numbers, stop the transaction immediately. Operating such a vehicle is life-threatening, and its registration is impossible.
Algorithm of actions before purchasing
To minimize risks, it is necessary to develop a clear sequence of actions. You should start checking with free sources, gradually moving on to more detailed and paid tools. Do not hesitate to ask the seller for documents and explanations regarding the history entries found. An honest seller will always meet you halfway and provide access to information; there is nothing to hide.
The first step should always be a visual verification of documents and appearance. Then - an online check using open databases. And only after making sure that there are no obvious “red flags” does it make sense to order a paid report and go for an in-person examination with a thickness gauge and a diagnostic scanner. This approach will save you money on paid reports for clearly problematic vehicles.

Frequently asked questions (FAQ)
Is it possible to check a car for an accident only by license plate without STS?
Officially, on the traffic police website, an STS number is required to obtain detailed information. However, many commercial services and third-party bots in instant messengers allow you to obtain basic information (year of manufacture, model, restrictions) only by license plate number, since they use their own databases parsed from various sources, including sales advertisements.
How often is the accident database updated?
The traffic police database is updated in real time after the inspector enters the data, but the delay can range from several hours to several days. Insurance company databases are updated less frequently, sometimes once a quarter, so new accidents may not be immediately displayed in aggregator reports.
What to do if there is an accident in the database, but the seller claims that the car was not damaged?
Most likely, the seller is disingenuous or has himself become a victim of fraud (for example, theft followed by theft). A detailed report with photographs must be requested. If the damage was serious, and the seller insists on cleanliness, this is a reason to refuse the deal. Minor scratches, registered through the insurance company, could simply be forgotten by the owner.
Does the collision inspection show damage sustained in a parking lot?
Only if the owner called the police or contacted the insurance company to receive payment. If you painted over a scratch in a parking lot yourself or at a garage service without paperwork, this information will not be in the databases. Only a thorough inspection of the body with a thickness gauge will help here.
Can you trust mileage data in accident reports?
Mileage data recorded when registering an accident or undergoing maintenance at official dealers can be trusted to a greater extent than the words of the seller. However, here too, operator errors are possible when entering data. It’s best to watch the dynamics: if the mileage increases logically, this is a good sign. Sharp jumps down or back are a sign of fraud.
