In areas where radar detectors are illegal, police commonly use radar detector detectors (RDD’s) to locate drivers who are running radar detectors. How do they work? How easily can they spot radar detector users? How effective are “undetectable” radar detectors at avoiding detection from a radar detector detector? Let’s take a look and cover everything you need to know about radar detector detectors.
A Quick Legal Note: I’m not a lawyer, and this is not legal advice. Laws change and I can’t guarantee this information is 100% accurate, current, or complete. If you’re facing a legal situation involving a laser jammer, consult an attorney in your state.

Quick Answer
Laser jammers are legal under federal law and legal in most US states. They are specifically banned in 11 states and Washington D.C.: California, Colorado, Illinois, Iowa, Minnesota, Oklahoma, South Carolina, Tennessee, Texas, Utah, and Virginia.
If you drive in or through any of those places, read this before running one.
Are radar detectors legal in your state? Laws vary depending on where you are and what type of vehicle you’re driving. Here’s a breakdown of radar detector laws in the US, how police find detector users, and where radar jammers stand legally.

Where Are Radar Detectors Illegal?
Virginia and Washington D.C.
All U.S. military installations: radar detectors are prohibited on every base. Note: there is no single federal statute covering this. The ban is enforced through individual installation regulations and base commanders’ orders. In practice it is universal, but you will not find one clean CFR citation the way you can for CMVs.
Commercial motor vehicles (CMVs) with a GVWR over 10,000 lbs operating commercially. Per 49 CFR 392.71, no driver may use or possess a radar detector in a CMV. A personal truck over 10,000 lbs GVWR does not qualify as a CMV.
Virginia note: If you are caught with a detector in Virginia, it is an equipment infraction under Code of Virginia § 46.2-1079. There is no confiscation, no points on your license, and the fine is typically around $40 plus court costs (total under $100).
Where Are Radar Detectors Legal?
In passenger vehicles, radar detectors are legal in all 49 other states. That means everywhere except Virginia, Washington D.C., and military bases.
Windshield Mounting Laws
Windshield mounting laws are separate from radar detector legality. Many states prohibit objects affixed to the windshield that obstruct the driver’s view.
California’s Vehicle Code § 26708 is a well-known example: it bans anything placed on the windshield with limited exceptions, including a 7-inch square in the lower corners. Minnesota has similar restrictions. These laws apply to any device, not just radar detectors.
Mounting options:
Suction cup on windshield: can be a violation in California, Minnesota, and several other states.
Blendmount (attaches to rearview mirror stem, not the glass): avoids the ‘affixed to windshield’ language in most states.
Police in areas where detectors are banned use radar detector detectors (RDDs) to find them.
The Spectre was the most widely used RDD. The company that made it has since gone out of business, so fewer of these will be on the road over time, but some remain in active use. Most consumer radar detectors can be detected by RDDs to varying degrees, with a handful of exceptions covered below.
Are Radar Jammers Legal?
No. Radar jamming has been illegal under federal law since 1996. The FCC enforces the Communications Act of 1934, which prohibits the operation, manufacture, importation, marketing, and sale of jamming equipment. Penalties start at $50,000 and can include prison time. No legitimate company sells radar jammers in the US.
Rocky Mountain Radar sells products they claim can scramble radar signals. They do not work. This has been tested repeatedly and the scrambling functionality is complete snake oil.
Undetectable Radar Detectors
When driving in prohibited areas like Virginia or D.C., many people want a detector that won’t be picked up by RDDs like the Spectre Elite. The following models are undetectable as of 2026:

Whistler is going to be introducing two new radar detectors that will be successors to their current top of the line radar detectors, the Whistler CR88 and Whistler CR93.
Blackvue has just announced an impressive new top of the line dashcam, the Blackvue DR900S. What’s special about the DR900S is that it now shoots in 4K (over the 1080p of the DR750S). Plus, to keep file sizes reasonably small, Blackvue is also introducing a new codec called H.265 that does an even better job of video compression than H.264 that was used before.
Update, Apr. ’18: You can now pre-order the DR900S!
Here at SEMA in Las Vegas, Radenso has brought their high end radar detectors out including the RC-M, Pro M (RPME), and XP. There are new updates available for the detectors so let’s go over the latest info regarding Radenso’s radar detectors.
There’s nothing new to report with the XP, but there’s new stuff regarding both the RC-M and Pro M, so let’s take a look at what’s new.
This week at SEMA, Escort has launched an update to the Max360 which they’re calling the Max 360c. It’s like a redesigned 360, with built-in WiFi, even more automation, and improvements to both performance and filtering! I will do a proper Escort Max 360c review once Escort sends me a detector after the show, but in the meantime I had a chance to talk to Escort (we actually spoke for a good two hours or so and it was an amazing experience) and they were excited to tell us all about their new top of the line radar detector. Watch the video below or keep reading to learn about what’s new with the Max 360c.
Differences Between the Max360 and Max 360c
I’m sure that by this point, almost all of you are familiar with the original Max360. If not, you can read my Max360 review here. I think the easiest way of telling you about the updated model is going over the changes and improvements between the Max360 and Max 360c, based on both what Escort has shared and my time taking a look at the detector. It has everything the Max360 has, plus more:
Wi-Fi built into the Max 360c (the ‘c’ stands for ‘connected’) which connects to your vehicle’s built-in WiFi
Automatically updates the detector to the latest firmware without having to connect to your computer
Automatically updates the detector to the latest redlight camera / speed camera database without having to connect the detector to your computer
Updated case and design
Physically smaller detector (thank goodness)
Arrows are now around the entire face of the detector, not around the rear horn
Case changes from all black to gray and black
Better button feel
Band Segmentation for both K & Ka band and the segments actually adjust what frequencies the detector sweeps for, and the segments adjust muting instead of performance or what frequencies are scanned, intended specifically for international usage
Improved performance Comparable performance compared to the Max360 (test results)
Improved blind spot filtering over the Max360 (Escort later changed their stance and said it’s the same as the original)
Improved arrow accuracy (will be verified once we have the detector on hand)
EZ Mag magnetic mount (my favorite radar detector mount)
Built-in integration with Escort’s soon-to-be-released (update: now available) ZW5 wireless laser jammers if you want an easy to install and feature-packed integrated radar / laser setup without drilling into your car or through your firewall
Price goes up from $649 to $699
My Initial Impressions of the Escort Max 360c
I haven’t had any seat time with the Max 360c yet of course, but I have had a chance to play around with the detector, turn it on, and buzz through the menu. Fortunately there’s some K band transmitters around so I had a chance to check out the detector’s arrows lighting up.
Design
I’m used to the arrows being around the rear horn on the original Max360 and it’s a little weird at first seeing the arrows wrap all around the display, but you get used to that quickly. I’ve also noticed that it looks better in person than it does in the stock photos for some reason.
Wi-Fi
The Wi-Fi integration is the main new thing. One of the big appeals of the Max360 was that it was a convenient and plug and play detector. Radar detector enthusiasts and tech savvy people in general don’t mind updating their detectors with their computer. However, simplifying the experience for people is a great thing. Being able to just leave your detector in your car and have it update both the firmware and the RLC/speedcam database automatically is a cool feature. You still get all the same Escort Live integration that you’d get with your phone and Bluetooth, but the automatic updating functionality is exclusive to Wi-Fi and fits the theme of a plug-and-play detector that does everything for you automatically, you know? I see it as more of a general consumer feature than a hardcore radar detector enthusiast feature.
Size
Escort has also slightly shrunken the detector as well. The Max360 was pretty massive, and as a Miata driver, I can appreciate a compact detector. 😉
Band Segmentation
Probably the biggest surprise to me is that there’s now band segmentation available that impacts performance. We’ve been told for years that BS/RDR isn’t needed for Escort’s digital detectors since it sweeps all of Ka band so quickly, but having an even faster scanning detector is a great feature. On the forums Escort is saying that the segmentation doesn’t impact performance, so we’re getting mixed messages, but that’s what we’re hearing.
Filtering
Escort is also making improvements to the BSM filter, always a welcome change. Apparently there’s also some improvements available for the Max 360c above and beyond what the Max360 will be capable of. According to Escort, this is more than just a slightly smaller Max360 with Wi-Fi.
Wireless Laser Jammer Integration
Finally, Escort is releasing a set of wireless laser jammers called the Escort ZW5 (wireless versions of the ZR5’s) that don’t need to have wires run through your vehicle’s firewall which means for a quicker and easier install that doesn’t affect your car as much. The Max 360c will interface with the ZW5’s to alert you when you’re shot with laser and you can press the mute button on your radar detector to kill your laser jammers. That’s a cool way to get a set of wireless jammers for your vehicle. Plus they don’t communicate via Bluetooth (which is a bit laggy and introduces a bit of a delay) so your RD will alert immediately when you get shot with laser.
Is It Worth It?
This detector is $700. It takes the most expensive radar detector on the market and raises the price. Is it worth it though?
I suppose if you were looking at the Max360 because you wanted that plug and play experience and you have Wi-Fi built into your vehicle then yeah, it would offer an even better experience.
The improvements to performance and BSM filtering I think remains to be seen. We’ve been told for so long that band segmentation won’t improve performance on a Max detector with DSP… but we were also told you can’t add BS/RDR to a Magnum because it didn’t have enough memory, but we eventually got BS/RDR on the Magnum so who knows? We’ll have to wait and see for independent testing to verify the improvements to performance and people driving with the detector to verify the improvements to BSM filtering to be sure, but nevertheless I do like seeing something new being brought out to the radar detector market.
The Max360 will still be available and is not being discontinued. Rather the Max 360c will be an additional detector for sale alongside the original.
If you have a Wi-Fi hotspot in your car already (many new cars are coming with it nowadays) and you’re really wanting a plug and play detector then yeah, the Max 360c will take things a step further.
Note: Escort doesn’t have a ton of these detectors initially. They’ve got a small number that will sell out quickly and then the main batch of detectors will arrive after the holiday season. Let me know if you order one and once you get it, let me know your real-world impressions and experiences with it so that we can compare notes and have more helpful information available about Escort’s latest radar detector.

The Escort iX is a convenient plug-and-play radar detector ideally suited to the everyday driver. It offers reasonable performance and false alert filtering, plus a number of unique and helpful features. In fact it’s a modernized update to Escort’s best selling detector of all time, the 9500ix. Let’s dive into this in depth Escort iX review.
Are you wondering what’s the best laser jammer? If you’re looking to protect yourself from costly speeding tickets, radar detectors are excellent against radar, but they’re almost useless against laser. In practice radar detectors are little more than ticket notifiers, only going off when the cop is already shooting you and has locked in your speed, and that’s if they even go off at all. Because laser is such a thin beam of light, aimed down at your license plate or headlights/taillights, often time your radar detector may not even alert in the first place.
To protect yourself against laser, you need a laser jammer, and a good laser jammer at that. Unlike a radar detector that has just a laser sensor inside it, a laser jammer will actively fire back at the police officer, preventing his laser gun from obtaining a speed reading whatsoever. Then your task, once the alarms start going off in your car, is to quickly slow down and disable your jammers, allowing him to get a speed reading on your car doing the speed limit, and you keep driving right along while the officer just shoots the next vehicle in line behind you.
Now when it comes to picking a laser jammer, what do you need to know? Are laser jammers legal where you drive? Which laser jammer should you get for your car? Let’s take a look.
