Are Radar Detectors Legal in Virginia? No: The Ban, Fines and Out-of-State Drivers

Last reviewed: October 18, 2026. This article is general information, not legal advice. Virginia laws change, so check the current Code of Virginia or ask a Virginia attorney if you are charged.

Virginia is the one state where the answer to "can I use a radar detector?" is simply no. If you live there, or you're driving through on I-95 or I-81 with a detector bought in another state, it's worth knowing exactly what the law bans, what it costs you, and the one narrow way to carry a detector legally. For the rest of the country, see our guide to where radar detectors are legal.

Short answer: no, radar detectors are not legal in Virginia. Virginia Code § 46.2-1079 makes it unlawful to drive on Virginia highways in a vehicle equipped with a detector, to use one, or to sell one in the state. The ban applies to everyone, including out-of-state drivers. A violation is a traffic infraction with a fine of up to $250 and no demerit points. The only safe way to carry one is with no power source and out of reach, such as boxed in the trunk.

What Virginia's ban covers

Section 46.2-1079 is broader than many drivers realize. It makes three separate things unlawful:

• Driving a vehicle "equipped with" a detector on Virginia highways.
• Using a detector on a vehicle on the highways.
• Selling a detector anywhere in Virginia.

It also covers more than radar. The wording reaches any device, "passive or active," that detects or interferes with "any radar, laser, or other device" used by police to measure speed. Laser detectors, combined radar/laser units and jammers all fall inside it.

Two rules make the ban easy to enforce:

• Presence is prima facie evidence. Except where the subsection B exception applies, the presence of a prohibited device in or on a vehicle on Virginia highways is prima facie evidence of a violation.
• It doesn't have to work. The statute says the Commonwealth "need not prove that the device or mechanism in question was in an operative condition or being operated." Unplugging it on the dash is not a defense.

There is one carve-out for receivers: the section doesn't apply to "any receiver of radio waves utilized for lawful purposes to receive any signal from a frequency lawfully licensed by any state or federal agency." That protects ordinary radios and licensed equipment, not devices built to detect police speed radar. Vehicles owned by the Commonwealth or a locality and used by law enforcement, and sales to law-enforcement agencies, are also exempt (subsection C).

Penalties: fine, no points, and the device

The fine. Section 46.2-1079 doesn't name its own penalty, so the default in § 46.2-113 applies: unless otherwise stated, violations of Title 46.2 are "traffic infractions punishable by a fine of not more than that provided for a Class 4 misdemeanor." Under § 18.2-11(d), a Class 4 misdemeanor carries "a fine of not more than $250." The actual amount is up to the court, and court costs are added.

No points. Subsection D says "No demerit points shall be awarded by the Commissioner for violations of this section." Points awarded before July 1, 1992 were rescinded.

The device. The statute doesn't allow forfeiture to the Commonwealth. The officer may take the device if needed as evidence, and it must be returned when no longer needed, or mailed to you at your request and expense. Unclaimed devices may be destroyed by court order six months after the final date for filing an appeal.

Out-of-state drivers: the ban applies to you

The statute applies to "any person" operating a motor vehicle on Virginia highways. There's no exception for visitors, for vehicles registered elsewhere, or for detectors bought legally in another state. If you're driving from North Carolina, Maryland or Florida, the detector has to be out of action before you cross the line.

To use the subsection B exception, both conditions must be true at the time you're stopped:

1. No power source. Unplug it, and ideally take the cord out of the socket and pack it separately.
2. Not readily accessible to the driver or any passenger. The trunk or a closed cargo area is the realistic choice. A glovebox, door pocket or center console is within reach, so it probably doesn't qualify.

Keep in mind that Washington, D.C. is stricter still: its rules ban possessing a detector in a car at all, so the trunk doesn't help there. If you're heading on to D.C., leave the detector at home.

Commercial vehicles: two bans at once

Virginia's statute already bans detectors in every motor vehicle, but commercial drivers face a second, federal ban. Under 49 CFR § 392.71(a): "No driver shall use a radar detector in a commercial motor vehicle, or operate a commercial motor vehicle that is equipped with or contains any radar detector." Motor carriers may not "require or permit" a violation (§ 392.71(b)).

The federal rule has no "no power source" exception like Virginia's. Under the federal definition in 49 CFR § 390.5, a device is excluded only if it is carried outside the driver's compartment and is "completely inaccessible to, inoperable by, and imperceptible to the driver" while driving. A commercial motor vehicle generally means one rated at 10,001 pounds or more, one carrying more than 8 passengers (including the driver) for pay or more than 15 not for pay, or one hauling placarded hazmat.

Jammers: also banned

Because the statute covers devices that "purposefully interfere with or diminish the measurement capabilities" of police radar and laser, both radar jammers and laser jammers are illegal to have equipped in a vehicle or sell in Virginia. Radar jammers are also illegal everywhere under federal law, which bans willful interference with licensed or government radio communications (47 U.S.C. § 333).

The FCC rule behind detectors

Radar detectors are regulated by the FCC under Part 15 of its rules. Since 2002, 47 CFR § 15.109(h) has required that "Radar detectors shall comply with the emission limits in paragraph (a) of this section over the frequency range of 11.7-12.2 GHz." The FCC adopted the limit after detectors were found leaking strong signals into the band used by small satellite (VSAT) terminals, and its 2002 order noted that manufacturers had moved to higher oscillator frequencies partly to make detectors harder for police to detect. An FCC-compliant detector is still illegal to use in Virginia; the federal equipment rule doesn't override the state ban.

Windshield mounts and dash cams

If you're a Virginia resident, the detector itself is the problem, not where it's mounted. But Virginia's view-obstruction statute matters for other devices. Va. Code § 46.2-1054 bans driving with objects suspended in a manner that would "substantially obstruct the driver's clear view of the highway through the windshield", and it expressly allows a dashboard camera and its wires if they are "wholly or mostly concealed behind the rear view mirror without any additional obstruction to the driver's view." The same section says officers may not stop a vehicle for a violation of it alone.

Military bases and Washington, D.C.

• Military bases. Virginia has many large installations. Federal rules for Army installations (32 CFR § 634.25) note that Defense Department policy delegates authority to installation commanders to set additional traffic rules, and detectors are widely reported to be banned on bases. Since state law already bans them in Virginia, the practical answer is the same.
• Washington, D.C. The District bans selling detectors and using or possessing one in a car (18 DCMR § 736).

Practical tips for Virginia

• Don't mount or plug in a detector anywhere in Virginia, even "just for the drive home".
• Do pack it unplugged in the trunk if you have to carry it through the state.
• Don't buy one in Virginia; selling them there is unlawful.
• Do contest a citation if your device truly had no power and was out of reach; that's the statutory defense.
