Virginia ISA (Speed-Limiter) Law and Reckless Driving

Start with the effective date and your offense date

Virginia DMV identifies July 1, 2026 as the Intelligent Speed Assistance Program’s effective date. That program date alone does not establish how the sentencing or pretrial provisions apply to earlier driving. The explanation below describes the rules for cases to which those provisions apply; it does not resolve transition questions.

Give your attorney the alleged offense date and ask which version of the law governs your case. Do not assume that a court date after July 1, 2026 answers that question.

When can a court require an ISA device?

Section 46.2-393(C) applies after conviction under either of these statutes:

• § 46.2-861: Driving too fast for highway and traffic conditions.
• § 46.2-862: Reckless driving by exceeding the speed limit.

For those convictions, a court may order enrollment in the Intelligent Speed Assistance Program as an alternative to court-ordered license suspension. That decision is discretionary and requires good cause shown. The enrollment period is at least 60 days and no more than six months. Participation still involves a restricted license, as explained below.

A charge alone does not trigger this conviction-based enrollment rule. The provision also expressly operates in addition to other penalties provided by law. ISA is not a substitute for the entire sentence.

Why the statute on your summons matters

Section 46.2-862 covers driving a motor vehicle on Virginia highways at least 20 mph above the applicable maximum speed limit or over 85 mph regardless of that limit. By contrast, § 46.2-861 addresses exceeding a reasonable speed under the circumstances and traffic conditions, regardless of the posted limit.

That means discretionary ISA enrollment is not limited to extremely high-speed cases. But you should not assume that every offense labeled “reckless driving” falls within this particular ISA provision. Start with the statutory citation, not the informal description of your ticket. The alleged speed alone does not tell you which offense your paperwork actually charges.

The special rule is over 100 mph—not exactly 100

The mandatory language in § 46.2-393(C) applies when you are convicted under § 46.2-862 and found to have driven on Virginia highways in excess of 100 miles per hour. The court must order enrollment for at least 60 days and no more than six months unless it has ordered license suspension under subsection A.

• Exactly 100 mph: This does not meet the special “in excess of 100” threshold. Discretionary enrollment may still be available for a qualifying conviction.
• More than 100 mph: With the required conviction and speed finding, enrollment is mandatory unless the court orders suspension under subsection A.

The speed on your summons is an allegation, not an already-established court finding. Ask your attorney to review the evidence supporting that allegation and explain what the court has actually found or ordered. The statute does not promise that you can simply choose a device instead of suspension.

What an ISA system does—and what happens to your license

Virginia Code § 46.2-507(A) defines an intelligent speed assistance system as one that limits a vehicle’s speed based on the applicable speed limit where it is being driven. The Virginia DMV’s program explanation describes GPS-based technology that determines the posted limit and automatically prevents the vehicle from exceeding it.

Participation does not mean keeping an unrestricted license. Although the sentencing statute describes ISA as an alternative to suspension, § 46.2-507(C) directs DMV, upon receiving the court’s notice requiring enrollment, to suspend the license and issue a restricted license indicating program participation.

Enrollment is a condition of obtaining and maintaining that restricted license. DMV cannot issue another license until you successfully complete the required enrollment period. Do not treat completion alone as confirmation that your unrestricted driving privileges have been restored; confirm your licensing status with DMV.

DMV identifies the Virginia Alcohol Safety Action Program (VASAP) as the program administrator. It explains that enrollment is managed through VASAP’s main office, with enrollment and participation activities completed online. Use the linked DMV page for current enrollment instructions.

For court-ordered participation, DMV directs you to enroll and then visit a DMV Customer Service Center to obtain the restricted license. Review your court order and DMV instructions together before assuming you are authorized to drive. Enrollment alone should not be treated as driving authorization.

Which vehicles need a device?

Under § 46.2-507(F), an enrolled participant must install a certified ISA system on each motor vehicle owned by or registered to that person. The participant also may not operate any motor vehicle without a functioning, certified system.

Those are separate obligations. Installing a device in your usual commuting car does not make it lawful to drive a borrowed car without one. Before discussing participation, list vehicles you own or co-own, vehicles registered to you, and vehicles you use for work or family transportation. A car you co-own deserves attention even if someone else usually drives it.

Commercial driving needs separate review: § 46.2-393(C) states that neither a restricted license nor enrollment required under that section permits operation of a commercial motor vehicle.

Costs and tampering

Section 46.2-507(G) requires participants to pay enrollment and participation costs unless the court or Commission finds them indigent. Here, “Commission” means the Commission on VASAP. Ask about actual costs and any indigency determination early; the statute does not set a single price.

Subsection M prohibits tampering or attempting to circumvent, bypass, or tamper with a system installed under that section. A violation is punishable as a Class 1 misdemeanor. If equipment malfunctions, seek program guidance rather than attempting to disable it.

Can you participate before trial?

Section 46.2-507(O) allows someone entering the program before trial to pre-qualify for installation on a vehicle owned or operated by that person. The court may consider that pre-qualification and installation.

This is not a requirement that every charged driver install a device before trial, nor a promise of sentencing credit. Discuss the applicable law and program requirements with your attorney before arranging installation.

Preparing for an ISA discussion about your Fairfax or Prince William case

The rules above are Virginia statutory rules, not a separate county ISA law. For a useful case review, gather:

• Your summons: The court name, statutory citation, alleged speed, applicable limit, and offense date.
• Any court or DMV paperwork: Keep the actual documents, rather than relying on a summary of what someone told you.
• Your vehicle list: Include shared ownership, registrations, borrowed vehicles, and employer vehicles.
• Your transportation needs: Explain your commute, family transportation, and any commercial driving responsibilities.

If you regularly drive between Fairfax and Prince William, keep your daily transportation needs separate from the court named on your summons. The practical question is not simply whether a device fits your own car, but whether the program’s vehicle requirements fit the driving you actually need to do.

Before arranging participation, ask VASAP or DMV where to find current certified-system information, what costs apply, whom to contact about equipment problems, and what steps are required when the ordered period ends. This guide does not provide vendor recommendations or a complete license-restoration checklist.

To find out whether ISA could apply in your case, ask a Virginia traffic attorney to review your summons, offense date, and any court or DMV paperwork. General website contact details are available on our contact page.
