Speed control is one of the most common sources of fines in Poland. Drivers often wonder whether the measurement was carried out correctly and whether its legality can be questioned. In practice, many cases arise due to procedural errors, incorrectly calibrated equipment, or the lack of mandatory documentation.
That is why the analysis of radar and photoradar measurements is of key importance. In the event of violations, it is possible to prepare a reasoned position to appeal a fine and verify whether the photo or measurement complies with legal requirements.
How do police radars work and when can the measurement be incorrect?
In Poland, various types of police radars are used, including hand-held devices, stationary photoradars, and systems installed in patrol vehicles. Each device must be used strictly in accordance with defined technical and procedural rules.
Speed measurement from a patrol car requires particular attention, as it is only valid under specific conditions. The patrol vehicle must maintain a constant speed, the distance must correspond to the device’s technical parameters, and the equipment must have a valid calibration. A violation of any of these elements may undermine the reliability of the measurement.
From what distance can the police measure speed?
One of the most common questions drivers ask is from what distance can a police officer measure speed. The answer depends on the type of radar, road conditions, and the technical specifications of the device used.
In practice, drivers also question:
- from what distance is speed measured in a specific situation;
- from what distance can the police measure speed during mobile enforcement;
- from how many meters can the police measure speed without a significant risk of error.
If a measurement is taken outside the permissible range or contrary to the manufacturer’s instructions, it may be challenged as unreliable evidence.
Why can radar speed measurements be inaccurate?
It is important to note that measuring the speed of a car with a police radar lasts very short. Because of this, the results may be affected by several external factors, including:
- other vehicles within the measurement zone;
- reflection of radar waves;
- road bends or lane changes;
- uneven road surfaces.
Even minor deviations from the prescribed procedure can result in inaccuracies that are difficult to detect without technical expertise.
Photo and speed measurement analysis – what should be checked?
A photo from a photoradar or a video recording constitutes only part of the evidence. A proper analysis should verify:
- whether the device had valid verification and legalization;
- whether the police officer followed the correct procedure;
- whether the distance from which the measurement was taken was properly determined;
- whether the calibration of the equipment was up to date;
- whether other vehicles could have influenced the measurement result.
In cases of mobile enforcement, it is also assessed whether road and traffic conditions allowed for proper speed measurement from a patrol car.
Why should you contact a lawyer?
Professional legal assistance helps determine whether there are grounds to challenge a fine and identify procedural or technical errors. A lawyer reviews documentation, requests technical specifications of the radar devices, checks compliance with legal standards, and prepares a structured legal position to protect the driver’s rights.
Illegal or inaccurate speed measurements occur more frequently than many drivers realize. Types of police radars, the distance of measurement, and strict compliance with procedures are critical to the legality of a fine. If there are doubts regarding from what distance can an officer measure speed or how the measurement was performed, the case should be carefully reviewed.
Consultant Legal Marketplace assists drivers in assessing the legality of photos and speed measurements, identifying potential violations, and developing an effective strategy to challenge unjustified fines. If you have doubts about a penalty, seeking professional advice can help protect your rights and avoid unnecessary sanctions.

Question
From what distance can police measure speed in Poland?
Answer
The distance depends on the type of radar and its technical specifications. Measurements outside the allowed range may be invalid.
