Why States Require Front Plates & How ALPR Detects Them?
The presence or absence of front license plates has become a topic of debate among drivers, law enforcement, and technology developers. While some U.S. states mandate both front and rear plates, others require only a rear plate, leading to a patchwork of regulations across the country.
This divergence not only affects legal compliance but also has implications for technologies like Automated License Plate Recognition (ALPR) systems, which rely on clear visibility of license plates to function effectively.
The Front Plate Divide: Map of Laws Across the U.S.
As of 2025, the United States presents a varied landscape regarding front license plate requirements. Twenty-nine states, including California, Texas, and New York, require both front and rear plates on vehicles. In contrast, twenty-one states, such as Florida, Pennsylvania, and Ohio, mandate only a rear plate.
Recent legislative changes have further shifted this balance. Ohio eliminated its front plate requirement in July 2020, citing cost savings and aesthetic considerations. Similarly, Utah's Senate Bill 45, passed in 2024, removed the front plate mandate effective January 1, 2025, aiming to streamline vehicle registration processes and reduce expenses.
Did You Know?
New Hampshire, known for its "Live Free or Die" motto, requires both front and rear plates. However, the state allows certain vehicles, like antiques, to display only a rear plate, reflecting a balance between regulation and individual freedom.
Real-World Workarounds & Opinions
Despite legal requirements, many drivers, particularly owners of vehicles like Teslas, opt to forgo front plates due to following concerns about vehicle modifications:
Aesthetic Concerns: Many Tesla owners feel that front plates disrupt the sleek design of their vehicles.
Risk of Damage: Some drivers worry that mounting a front plate could damage sensors or paintwork.
Creative Solutions: To balance legality and aesthetics, some employ removable mounts, or even magnetic holders.
Why States Require Front Plates?
The rationale for mandating front license plates encompasses several practical considerations:
Law Enforcement: Front plates aid in identifying vehicles involved in crimes or traffic violations, especially when approached from the front.
Toll Collection: In regions with front-facing toll cameras, front plates ensure accurate billing.
Parking Enforcement: Front plates facilitate identification in angled or head-in parking scenarios.
Public Safety: They assist in AMBER alerts and tracking stolen vehicles.
Matter of Visibility, Not Vanity
While some view front plates as an aesthetic nuisance, their primary function is to enhance vehicle visibility for safety and enforcement purposes.
However, enforcement of front plate laws varies. In some states, it's considered a secondary offense, meaning drivers are only cited if stopped for another violation. This inconsistency contributes to the ongoing debate over their necessity.
ALPR Systems & Front Plate Detection
Automated License Plate Recognition systems are pivotal in modern traffic management and law enforcement. These systems capture and analyze license plate data to monitor traffic flow, identify stolen vehicles, and enforce laws.
The presence of front plates significantly enhances ALPR effectiveness:
Increased Detection Rates: Vehicles can be identified from both directions, reducing blind spots.
Improved Accuracy: Dual-plate recognition minimizes errors in plate reading.
Enhanced Data Collection: More comprehensive data aids in traffic analysis and planning.
However, in states without front plate requirements, ALPR systems face challenges in capturing complete data, especially in scenarios where rear plates are obscured or unreadable.
Worth mentioning Sighthound ALPR+, an advanced solution that transcends traditional plate recognition. Beyond reading license plates, it identifies vehicle make, model, color, and generation (MMCG), as well as class and orientation.
This multi-layered approach ensures accurate vehicle identification, even when a plate is missing or unreadable.
Privacy Assurance
Sighthound ALPR+ is designed with privacy in mind. It processes data locally without storing license plate information, allowing users to integrate insights into their systems without compromising personal data.
Policy, Privacy, and the Future of ALPR Compliance
Undoubtedly, the ALPR systems offer undeniable benefits in safety and efficiency, however, they also raise concerns about surveillance and data misuse.
Unlike traditional systems that rely solely on license plate data and cloud storage, ALPR+ processes vehicle insights entirely at the edge, without storing any PII or transmitting plate numbers by default. It doesn’t just "read plates", it recognizes MMCG, class, and orientation. That means even if a vehicle lacks a front plate, or the rear plate is obscured, the system can still provide actionable, multi-layered identification in real time.
As policymakers wrestle with how to balance surveillance with civil liberties, and as drivers continue to remove or obscure their front plates out of personal preference, a shift is occurring. The future of ALPR may not rest solely on plate visibility, but on a broader, AI-powered understanding of the vehicle itself.
Privacy-forward, enforcement-smart, and adaptable to every plate policy in the U.S., Sighthound ALPR+ represents a modern answer to an increasingly complex problem.

Front plate requirements vary by state due to differences in law enforcement priorities, infrastructure, and political culture. States that require both front and rear plates typically cite improved vehicle identification for tolling, red light cameras, and police visibility as key reasons. Rear-only states often emphasize aesthetics, cost savings, or minimal enforcement capacity. While there’s no federal standard, the trend is shifting in some areas, like Utah removing its front plate requirement starting 2025, showing that these rules are fluid and locally debated.
-
Yes, if a state mandates both plates, driving without the front plate is technically illegal, but enforcement varies widely. In many states, it’s considered a “fix-it” ticket or secondary offense, meaning police may only cite you for it if you’re stopped for another reason. Local enforcement culture matters as much as the law.
-
ALPR systems work best when they can read plates from multiple angles, especially during head-on encounters like intersections, parking lot exits, or toll booths. Without a front plate, vehicles may go undetected in these situations, especially at night or in high-speed motion. That’s why many law enforcement agencies advocate for front plates: they double the opportunity for detection and improve hit accuracy. However, advanced systems like Sighthound ALPR+ mitigate this by also analyzing the vehicle’s make, model, color, generation and other identifying attributes, providing multi-factor recognition even when a plate is missing or unreadable.
-
Yes, privacy concerns are common among drivers and digital rights advocates. Some worry that constant surveillance, especially if ALPR cameras track both front and rear plates, could lead to mass data collection or misuse. However, not all ALPR systems store plate data. For instance, Sighthound ALPR+ is designed with privacy in mind: it processes license plate and vehicle data locally and does not retain or transmit personal information. Responsibility for data retention lies with the organization using the software, whether that’s a city, agency, or private operator.

If your front plate goes missing in a state that requires it, you're typically expected to replace it through your local DMV. Most states offer a way to request a replacement plate or set, but driving without one can still result in a citation, even if it’s unintentional. It’s best to fix or replace your plate sooner than later to avoid enforcement issues.
