License Plate Reader Technology

Since their inception in 1976 at the Police Scientific Development Branch in the United Kingdom, License Plate Readers have evolved significantly. These sophisticated systems are now utilized by law enforcement agencies worldwide to automatically record and assess license plate numbers, supporting traffic monitoring and management, including detecting traffic offenses. LPR technology has proven to be a valuable asset in bolstering public safety, enhancing security, and optimizing traffic management for those holding a Pennsylvania driver’s license.
Using cameras and algorithms, LPR technology captures and analyzes images of license plates to extract their numbers. This enables the identification and recording of vehicles in real-time, as well as the tracking of their past locations, which can be helpful in detecting serious traffic offenses. In Pennsylvania, the point system ranges from 2 to 5, depending on the gravity of the infraction, and LPRs can help identify violations that contribute to points on a driver’s record.
How License Plate Readers Work
Using cameras and software, License Plate Readers capture and analyze license plate numbers, offering real-time data to law enforcement agencies for detecting traffic violations like Not having Insurance or driving on a suspended license. These systems typically utilize:
Infrared and visible-light cameras to scan the surrounding area for license plates
Some systems able to capture and process one car per second
Optical character recognition (OCR) technology to extract the license plate numbers
Comparison against a database of wanted vehicles or vehicles associated with suspects
This allows law enforcement, such as a police officer, to monitor the vehicle’s owners license status, and take the necessary action, and once the car is on the side of the road, the vehicle can be ticketed for any other infraction the officer observes.
The software used for data analysis in License Plate Readers may vary, with examples including advanced data analysis software, ALPR analytics software, and Vigilant VehicleManager license plate analytics software. License Plate Readers can help law enforcement identify traffic violations, which may impact car insurance rates for drivers. With their impressive processing speed and accuracy, LPRs are highly effective in the context of traffic monitoring and management, including in Pennsylvania.
Applications in Law Enforcement
License Plate Readers serve various purposes in law enforcement, including locating stolen vehicles, tracking suspects, and enforcing traffic laws. By capturing images of license plates and automatically recognizing and recording the information, LPR systems provide valuable data that can be used as evidence in traffic court proceedings.
In Pennsylvania, the point system for evaluating penalties on a Pennsylvania driver’s license, known as Pennsylvania’s point system, ranges from 2 to 5, depending on the gravity of the infraction. Accumulating six or more points on a driver’s license can lead to potential suspension, regardless of the individual infractions’ severity. Identifying violations contributing to points on a driver’s license and upholding traffic laws are crucial roles played by LPR technology.
In addition to detecting traffic violations, LPRs can be used to track suspects by comparing the captured license plate numbers against a database of wanted vehicles or vehicles associated with suspects. If a match is found, law enforcement can monitor the vehicle’s movements and take the necessary action. With their ability to quickly process thousands of license plates per minute, License Plate Readers have become an essential tool in law enforcement operations, enhancing public safety and security.

Potential Drawbacks and Controversies of License Plate Readers

Despite proving to be a valuable tool for law enforcement and traffic management, License Plate Readers are not without their potential drawbacks and controversies. Some concerns include:
The possibility of false positives, which can lead to unwarranted traffic citations or other legal issues.
The potential for racial profiling, as LPR technology may be used to target certain communities disproportionately, leading to biased law enforcement practices.
The cost and resource allocation for LPR technology may be a point of contention, as some argue that funds could be better spent elsewhere.
Despite these concerns, License Plate Readers continue to play a crucial role in traffic enforcement and monitoring. By understanding the potential drawbacks and controversies surrounding LPR technology, we can work to address these issues and ensure that this technology is used responsibly and effectively to promote public safety and traffic management.
False Positives and Errors
False positives and errors from License Plate Reader technology could result in unjust traffic citations or other legal complications. Common causes of false positives include:
Misinterpretation of characters
Similarity between license plates
Environmental factors
Database errors
While the frequency of false positives can vary, estimates suggest that one out of every ten license plates may be misread, resulting in a lower accuracy rate.
When challenging a License Plate Reader-issued ticket, it is essential to consider the possibility of false positives or errors in the LPR system. By questioning the accuracy of the technology and the legality of its use in specific circumstances, individuals can contest unwarranted traffic citations and protect their driving record.
Increase in the overall amount of motor vehicle stops
The deployment of License Plate Readers has led to an upsurge in motor vehicle stops, which is a cause for concern. This increase in stops has not only led to an escalation in traffic disruptions, but also raised questions about possible misuse of technology and the potential for unwarranted stops. There have been instances where drivers have been pulled over based on data from license plate readers, leading to unnecessary confrontations and potential misuse of police power. Despite the measures implemented to prevent such instances, the potential for excessive and unwarranted stops remains a significant concern in the use of LPR technology.
Over the past few years, Pennsylvania has seen a notable increase in the number of traffic stops. According to the Pennsylvania Uniform Crime Reporting System, there were approximately 1.5 million traffic stops in 2015. By 2019, this figure had risen to over 1.8 million, marking a 20% increase. This trend has continued, with preliminary data for 2020 showing an estimated 1.9 million traffic stops. This surge in motor vehicle stops largely attributes to the deployment of License Plate Readers across the state.
If you believe that you have been unfairly targeted in connection with an LPR-issued traffic citation, The Shelton Firm can provide the legal expertise and support necessary to challenge the violation and protect your rights.
License Plate Readers and Traffic Tickets

License Plate Readers significantly contribute to traffic ticket issuance, automated traffic enforcement, and detection of common traffic violations. In Pennsylvania, traffic violations detected by LPR can result in fines, points on your driving record, and even suspension of driving privileges. If you find yourself facing a traffic ticket issued by an LPR, it is crucial to understand the technology and the legal strategies available to challenge the violation.
In the following sections, we will discuss:
How automated traffic enforcement systems like LPRs issue traffic tickets

How individuals can challenge a License Plate Reader-issued ticket
Automated Traffic Enforcement
Automated traffic enforcement systems like License Plate Readers can issue traffic tickets without the need for direct human intervention. These systems utilize cameras to collect images of drivers violating traffic regulations, for example, speeding or running red lights. The cameras record pertinent data concerning the violations and capture pictures of the violator vehicles. Subsequently, citations are issued based on the obtained evidence.
License Plate Readers:

Do not directly detect speeding, as they are primarily used to capture and record license plate information
The actual detection of speeding is usually done using other methods, such as radar or laser speed guns.
Common Traffic Violations Detected
License Plate Readers commonly detect traffic violations such as speeding, running red lights, and expired registration. LPRs utilize Automatic License Plate Recognition (ALPR) technology to identify expired registrations. While they do not directly detect speeding, LPRs can be used by law enforcement agencies to identify vehicles that may have been involved in speeding by capturing and recording license plate information along with the date, time, and location of the vehicle.
If you have been issued a traffic ticket based on a violation detected by a License Plate Reader, it is essential to understand the specific circumstances of the violation and the potential legal strategies available to challenge the citation.
Challenging a License Plate Reader-Issued Ticket

If you’re challenging a ticket issued by a License Plate Reader, you may need to question the technology’s accuracy or its legality in your specific situation. To contest a traffic violation in Pennsylvania, you can either request a contested hearing at the relevant county court by signing the “not guilty” line of the citation and mailing it to the court, or you can call The Shelton Firm for a free consultation and discuss your options.
Factors such as the traffic patterns at the time of the measurement, improper calibration of the radar device, and human error by the device operator may contribute to a successful challenge for exceeding special speed limit violations based on radar devices.
