Avoid Speeding Tickets: Experts Pick the Top Radar Detectors of 2024 (2024)

A massive upgrade from the first-gen V1, the Gen2 features a magnesium case and brand-new guts adapted from military chirp radars. It's a far cry from the Gen1.

Both K- and Ka-band ranges have been improved, and the V1 Gen2 features what Valentine calls "K-verifier technology" for better resistance, to more accurately filter signals from blind-spot-detection systems on other cars and automatic doors on storefronts. Built-in Bluetooth 5.0 enables a wireless connection to both Apple and Android smartphones and tablets, and the app is intuitive.

The Gear Team tested several of the radar detectors on this list extensively and found the 2.1-mile rear-detection range on the V1 Gen2 far and away the best of the bunch. It was also the "chattiest" device we tested, pinging its alerts loudly and often.

Escort's complete driver-alert system does far more than alert you to the presence of speed enforcement—this bundle offers the Redline 360C with a dash cam. In addition to 360-degree radar detection, the M2 dash cam ($200 purchased separately) continuously records video footage of your driving, serving as evidence in case of accidents or other incidents on the road.

In testing, the Gear Team found that the Escort's performance was competitive with other top-of-the-line radar detectors. It stood out for its Waze-like navigation function, and we found the Escort community of users (via the amenable Drive Smarter app) to be surprisingly vast and engaged. People who use the 360C love it.

We particularly like that Escort offers trade-in value on old devices, price matching, and free shipping, plus it guarantees its products by paying for any traffic tickets you may receive while using its radar detectors.

While this two-in-one bundle is surely a breakthrough in both radar detectors and dash cams, many of us already have one or both of these devices in our cars. Still, with this package you can reduce windshield clutter and simplify your driving experience.

The R8 is Uniden's top-of-the-line radar detector. It can identify threats coming from all four directions thanks to its dual 360-degree antenna, and you get notified via voice alerts. Even the band, direction, and signal intensity for each are audibly announced. If voice alerts annoy you, it also features a large multicolor OLED display.

It's preloaded with Red Light and Speed Camera locations, and firmware and data upgrades are free, so you always have the latest information at your device. Best of all, it's Spectra Elite undetectable, so police who scan traffic for cars with radar detectors won't locate it.

We were impressed with the R8's performance. It's pricey but offers a massive two-mile detection range, which was second only to the Valentine in our testing.

The Escort Max 360c MKII comes loaded with the latest tech. It has two antennas for maximum range, directional arrows that help you quickly identify risk, and an auto-learn feature that remembers false alerts on your commonly used routes. The MKII improves upon the performance of the Redline 360C with 50 percent improved range, faster performance, and fewer audible false alarms.

It also features Escort's intuitive app that makes it easy to adjust settings, and you can opt into Escort's Defender subscription plan, which allows you to use built-in Wi-Fi to download traffic-detection database updates automatically.

We haven't had the opportunity to use the MKII in real-world testing yet, but we look forward to what one of the leaders in radar-detection devices has to offer with its latest product.

Most radar detectors require you to reach the device mounted on your windshield to access features or adjust the volume. This Platinum 100 bundle from K40 solves that issue with a remote control. We're a bit dubious; fishing around for a remote that's buried in your glovebox or center console might lead to some distracted driving. (You can purchase just the Platinum100 without the remote for far less.) Still, the LNA technology provides maximum range and sensitivity and enhanced filtering options.

K40 also offers a user-friendly 12-month "ticket-free guarantee" that will cover your court costs if you get a radar or laser speeding ticket within the first year of your purchase. There are some exceptions—it's not valid in school or construction zones, or in conjunction with a DWI, for example. But we love this feature for the confidence K40 has in its products.

The bestselling radar detector on Amazon comes from one of the most renowned names in radar detection. With two times the detection range of its predecessor for advanced warnings, plus next-gen IVT filtering to eliminate unwanted alerts, the RAD 480i is a great radar detector for the price.

Bluetooth connectivity allows you to access the Cobra community and receive real-time driver-speed and red-light-camera alerts from the Cobra driving community via Cobra's iRadar app, including red-light, speed-cam, and law-enforcement detection notifications.

In our testing, the DS1 performed admirably in range, sensitivity, and ease of use. It didn't necessarily stand out in any particular way, but it easily kept up with much higher-priced radar detectors in most facets of performance.

It also offers many of the high-end features those pricier options boast, like GPS, Bluetooth, fast USB-C charging, a color OLED display, and a magnetic mount, as well as "stealth to radar detector" detectors sometimes used by law enforcement. It even has a magnetic suction-cup mount that allows you to stow it when not in use or swap it between vehicles. If you're looking for a high-quality radar detector but don't want to pay upward of a thousand bucks for it, try the DS1.

Radar detectors detect the various radar bands emitted by police radar guns. The most common bands are X, K, and Ka. X-band is older and is mostly obsolete. K-band is more prevalent in suburban areas. Ka-band is the most widely used radar band these days. Most highway-patrol departments use Ka-band.

Understanding these bands helps in selecting a radar detector that effectively alerts you to potential speed traps and enhances your driving awareness.

X

X-band alerts indicate the detection of radio waves in the 8.0-GHz to 12.0-GHz range. It is the oldest radar frequency, and many radar-detector users disable X-band alerts on their radar detectors. You may want to think twice before ignoring it altogether, though, as some local police or highway patrol may still use older radar guns.

K

Operating between 18.0 GHz and 27.0 GHz, K-band radar isn't as prevalent as it once was, but that doesn't mean it's obsolete. False alerts on car radar detectors are fairly common, as signals from modern driver-assistance tech like lane-departure, adaptive cruise control, and blind-spot monitoring operate on K-band frequencies. Even motion-detecting automatic doors on storefronts use K-band, so just driving by your local market can result in a false alarm.

Ka

Typically operating at 33.8, 34.7, and 35.5 GHz, Ka-band radar has become a favorite of law enforcement as it is much more difficult to detect. Since false alerts on the Ka-band are rare, a Ka alert from your detector is likely a genuine indication of police presence, so stay alert.

What's the best radar detector?

While there's no simple answer to which is the "best," the most reliable radar detectors are those with a range of at least 1.5 miles and that can ignore false alarms while sounding an early warning for genuine speed traps. Because they can block out obtrusive signals from radar-controlled door openers, those with GPS offer a significant advantage. As with most tech and gadgets, you usually get what you pay for.

Can a patrol car clock my speed while it's moving?

Yes, and moving radar is more effective than static radar, meaning a moving patrol car using radar gets even more accurate readings than a parked one. The majority of these radars provide front-rear coverage, so vehicles traveling in the same direction either in front of or behind a rolling cruiser can be tracked.

The fastest car in a group can also be targeted. Meeting an approaching cruiser is the most common situation where moving radar is used.

Are radar detectors legal?

Radar detectors are permitted everywhere in the United States besides Virginia, Washington, D.C., and military sites. These rules only apply to passenger cars. Radar detectors are prohibited in all areas of the country for commercial trucks over 10,000 pounds and all vehicles over 18,000 pounds.

Radar jammers, however, are illegal in every state. Ten U.S. states, namely California, Colorado, Illinois, Minnesota, Oklahoma, South Carolina, Tennessee, Texas, Utah, and Virginia, as well as Washington, D.C., have laws prohibiting the use of laser jammers.

Why is my radar detector alerting even when there are no cops around?

Your radar detector may be activated by a variety of radar sources. Only one such source is police radar. Other sources that may create a false alert include speed signs on the side of the road, automatic door openers in front of stores that use radar to detect when someone is approaching, and even some late-model vehicles with radar-based blind-spot-monitoring and collision-avoidance systems.
