Toll Camera Avoidance: Illinois Criminalizes Covers That Block Toll Cameras
Concealing your plate rarely guarantees you will dodge a toll charge, and in many states it is illegal. Illinois, for example, criminalizes covers or coatings that block electronic image recording on toll highways. Agencies can also match your vehicle across gantries. If you get a notice you think is wrong, dispute it with the toll agency.
TL;DR:
- ALPR systems can exceed 95% accuracy in ideal conditions, but weather, viewing angle, or a dirty plate can justify disputing a mistaken charge.
- Illinois can confiscate obscuring devices, fine plate covers $750 and chemically altered plates $1,000, revoke registration, and pursue sellers through civil suits.
- Toll agencies may combine images from multiple gantries to link a vehicle, so blocking one camera capture does not reliably prevent billing.
- Submit a toll dispute before the stated deadline, because late penalties may accrue while it is pending; compare the notice with trip records and receipts.

What do people try to avoid toll cameras?
Search any forum and you will find the same handful of tricks. Many of the products behind them are sold openly online, even as state restrictions tighten.
- Plate covers: tinted, reflective or “anti-photo” shields meant to wash out the image.
- Sprays and coatings: glossy films that claim to bounce camera flash back at the lens.
- Mechanical flip or roll devices: a plate that tilts or rolls out of view on demand.
- Temporary occlusion: a hand, a bike rack, a towel or a tow hitch placed in the way.
- Removing a plate: pulling the front or rear plate before a toll point.
The reliability story is poor. Toll systems are built around lighting and camera placement that simple obfuscation struggles to beat, and you rarely learn whether a trick worked until a notice arrives. Several of these methods also fall squarely under the bans covered below.
Pro Tip: Before you buy anything that alters how your plate looks, check your state’s statute on obscuring devices. “Sold online” does not mean “legal to use.”
How do toll cameras and toll-by-plate billing work?
Toll-by-plate starts with a camera capturing your plate, software reading the characters, and an invoice going to the registered owner. On the Pennsylvania Turnpike, missing the payment deadline often leads to escalating administrative fees and late penalties.
Automatic license plate recognition (ALPR) takes images and runs optical character recognition on them. The hardware is deliberately engineered for difficult conditions. The Federal Highway Administration’s design guidance for violation enforcement systems covers camera mounting angles, trigger distances and lighting choices such as pulsed LEDs and infrared, all aimed at reliable plate capture. New York’s DMV notes that this kind of advanced lighting is meant to overcome visual interference, which is why drivers rarely know whether a cover blocked anything.
Accuracy cuts both ways. ALPR image capture can exceed 95% accuracy in ideal conditions, but weather, off-axis viewing and dirty plates cause misreads.
That second half matters for honest drivers. A misread is a legitimate reason to dispute a charge. It is not a design flaw you can count on exploiting, because the systems are built with engineered triggers and redundancy so a single trick seldom defeats them. As Callmc points out, real-world variables explain misreads, and those misreads are exactly what the dispute channel exists to correct.

What are the legal and enforcement consequences in the U.S.?
States increasingly ban the possession, sale and use of plate-obscuring devices. Illinois shows how specific the language gets: its toll statute authorizes citation and confiscation of the device, with fines of $750 for a plate cover and $1,000 for chemically altered plates. It also allows registration revocation and civil suits against sellers, and it exempts authorized transponders (605 ILCS 10/27.2).
Other states follow the same direction:
- Florida prohibits obstructing plate legibility, with consequences tied to registration and, in some cases, criminal charges.
- New York has new laws banning the sale of plate covers and raising penalties for obscuring plates.
- Massachusetts lawmakers have considered a bill targeting tinted covers, citing toll revenue recovered elsewhere after stricter enforcement.
- Enforcement drives such as the MTA crackdown on obscured plates show agencies actively chasing lost revenue.
Detection does not depend on one clean photo. Toll agencies often stitch together images from multiple gantries to build a vehicle profile, so blocking one capture rarely stops them from linking your car across locations. Regulators are also moving up the supply chain: new rules in places like New York and Massachusetts target sale, distribution and installation of products designed to bypass enforcement.
Laws differ by state and change often. Our state-by-state breakdown of plate cover laws is a good next read.
What should you do if you get a toll notice or citation?
If the notice looks wrong, act quickly and keep everything on the record. Disputing through official channels beats any workaround.
- Check the notice details. Compare plate, date, time and location against your own records.
- Verify the sender. Confirm the toll authority’s contact information on its official website, not from the notice itself, since plate cloning and fraudulent notices are possible.
- Gather evidence. Trip logs, receipts, photos and dashcam footage all help.
- Contact the toll authority’s customer service and follow its dispute process, submitting your documents within its stated window.
- Report suspected cloning or theft to your DMV and local law enforcement.
- Bring in a lawyer only if needed, for example if the matter escalates to a citation or court date.
Pro Tip: Respond before the payment deadline even if you are disputing the charge. Late penalties can pile up while a dispute is pending.

Why does toll avoidance rarely succeed over time?
Because the odds stack against any single trick. ALPR is accurate in good conditions, and the environmental factors that reduce accuracy only open a limited window for legitimate disputes. Agencies connect multiple images and vehicle characteristics, so a temporary tactic does not hold up against repeated trips.
Privacy advocates make a similar point from the other direction: avoiding ALPRs entirely in the U.S. is nearly impossible given how many cameras law enforcement, transit agencies and private entities run. Their realistic suggestions combine route awareness and civic action rather than technical evasion.
If cost is the real issue, the dependable options are plain ones. Navigation apps offer an “avoid tolls” setting that reroutes you around toll roads. Check with your toll authority to learn how using a transponder affects plate billing. Disputing real errors through official channels works better than hoping a camera misses you.
Our perspective on plate privacy and lawful use
We build electric and mechanical blackout covers because plenty of drivers want on-demand control over who sees their plate, and we understand why. That does not erase the legal complexity. Rules vary by state and by situation, so check your state and local laws and use any product lawfully. Our blog goes deeper on license plate privacy options and whether plate covers work.

FAQ
Can I set Google Maps to avoid toll roads?
Yes. Google Maps, Waze and Apple Maps all include an “avoid tolls” route option in their route or navigation settings, and it recalculates your trip to minimize toll roads. Expect a longer drive in some cases.
How do I get out of a toll violation?
If the charge is wrong, dispute it with the toll authority using your records, such as time, date and vehicle details. Check the toll authority’s official website for the applicable deadline. Misreads from weather or dirty plates are a recognized basis for disputes.
Do toll agencies track cars across multiple toll points?
Often, yes. Agencies commonly combine images from several gantries to build a vehicle profile, so blocking one capture rarely stops them from linking your vehicle.
Is it legal to use a plate cover on a toll road?
It depends on your state, and many states prohibit obscuring devices. Illinois, for example, fines plate covers on toll highways, so check your state’s statute first.
