Interlock Device Bypass under NY VTL § 1198(7)(b) makes it a crime to knowingly rent, lease, or lend a motor vehicle to a driver whose driving privilege is restricted to vehicles equipped with an ignition interlock device (IID), unless that vehicle has an IID installed. This New York law targets third parties, including family members, friends, employers, and rental agencies, who provide a non-equipped vehicle to a restricted driver. The New York Criminal Jury Instructions classify this offense as a misdemeanor, which can carry jail time, fines, and a permanent criminal record.

Mr. Jason Bassett treated my son’s case with respect, he showed empathy and was very patient with the many concerns I had during my son’s court dates. Very professional and if I have to use him again there would be no question that I would. I would most definitely recommend him.
New York Vehicle and Traffic Law § 1198(7)(b) states the following prohibition:
“No person shall knowingly rent, lease, or lend a motor vehicle to a person known to have had his or her driving privilege restricted to vehicles equipped with an ignition interlock device unless the vehicle is so equipped. Any person whose driving privilege is so restricted shall notify any other person who rents, leases, or loans a motor vehicle to him or her of such driving restriction.”
In simple terms, this law prohibits anyone from knowingly lending, renting, or leasing a vehicle to a driver who is required to use an ignition interlock, unless that vehicle has the interlock device installed. New York Vehicle and Traffic Law § 1198(7)(b) is often referred to as an “interlock device bypass” because it involves bypassing the safety requirement meant to prevent drunk driving. The statute also places a duty on the restricted driver to notify anyone who might provide them with a vehicle about the restriction.
While the statute itself doesn’t use the word “bypass,” this offense is commonly described as bypassing the interlock requirement because it involves helping a driver get around the IID restriction. The law uses the term “circumvent” for related offenses (for example, VTL § 1198(9)(c) prohibits tampering to “circumvent” an IID).
The word “knowingly” in the statute means this is not a strict liability offense. Under New York Penal Law § 15.05(2), a person acts “knowingly” with respect to conduct or a circumstance when that person is aware that the conduct is of that nature or that the circumstance exists. Applied to VTL § 1198(7)(b), this means the person renting or lending the vehicle must be aware that the other driver is restricted to vehicles equipped with an ignition interlock device and must knowingly provide a vehicle that is not so equipped.
A person who lends a vehicle without knowing about the ignition interlock restriction has a stronger argument that the statute was not violated. In practice, a charge under VTL § 1198(7)(b) will generally depend on proof that the person providing the vehicle knew about the driver’s IID-related restriction when providing access to the vehicle.
VTL § 1198(7)(b) applies to anyone who rents, leases, or lends a motor vehicle, not just family members and friends. This could include commercial rental agencies, fleet operators, and dealerships that provide loaner vehicles. If an agent processes a rental agreement knowing the customer has an IID restriction, the agency and the individual who processed the rental could face charges.
In practice, most commercial rental agencies rely on standard license checks during the rental process. A customer’s driver’s license may carry a notation or restriction code indicating IID requirements, which rental staff are expected to verify. However, if a rental agent genuinely did not know about the restriction and the customer presented a seemingly valid license, the knowledge element would be harder for prosecutors to prove.
Key Takeaway: VTL § 1198(7)(b) makes it a misdemeanor to knowingly rent, lease, or lend a vehicle without an ignition interlock device to someone whose driving privilege requires one. The law applies to anyone who provides a vehicle, including businesses and rental agencies, but requires proof that the provider knew about the restriction.
New York has several related offenses to ensure drivers do not circumvent ignition interlock device (IID) requirements. These laws, all found in Vehicle and Traffic Law (VTL) § 1198, were enacted as part of the provisions under Leandra’s Law, mandating IID installation for most DWI offenders. Key related offenses include:
| Offense | Statute | Alleged Conduct | Offense Level |
|---|---|---|---|
| Operating Without an Interlock | VTL § 1198(7)(a) | Operating a vehicle without a required IID | Misdemeanor |
| Lending a Non-IID Vehicle | VTL § 1198(7)(b) | Knowingly lending or renting a non-equipped vehicle to a restricted driver | Unclassified misdemeanor |
| Soliciting Another to Blow Into IID | VTL § 1198(9)(a) | Asking another person to start the vehicle or blow into the IID | Class A misdemeanor |
| Assisting an IID-Restricted Driver | VTL § 1198(9)(b) | Helping a restricted driver obtain an operable vehicle | Class A misdemeanor |
| Tampering With an IID | VTL § 1198(9)(c) | Circumventing or tampering with the device | Class A misdemeanor |
| Operating Without Required IID | VTL § 1198(9)(d) | A restricted driver operating a vehicle without an IID | Class A misdemeanor |
All of the above are misdemeanor offenses under VTL § 1198. The law also requires an IID-restricted driver to notify a person who rents, leases, or loans a motor vehicle to that driver of the restriction. This places the obligation on both the driver and others who may provide access to a vehicle.
The offenses under VTL § 1198(9) address conduct by the restricted driver or by a person who directly interacts with the ignition interlock device or vehicle to help the restricted driver obtain an operable vehicle. The statute expressly classifies violations of VTL § 1198(9)(a), (b), (c), and (d) as Class A misdemeanors.
VTL § 1198(7)(b), by contrast, applies to the third party who knowingly rents, leases, or lends a vehicle to a person known to be restricted to IID-equipped vehicles unless that vehicle is so equipped. VTL § 1198(7)(c) states that a violation of § 1198(7)(a) or (b) is a misdemeanor.
In some cases, both parties may face separate charges. A restricted driver who operates a non-equipped vehicle may be charged under § 1198(9)(d), while the person who knowingly provided that vehicle may be charged under § 1198(7)(b)
Key Takeaway: VTL § 1198(7)(b) focuses on providing a non-equipped vehicle to a restricted driver, while VTL § 1198(9) focuses on operating without the device, tampering with it, or helping a restricted driver obtain use of a vehicle through direct interaction with the IID or vehicle.

Jason Basset was the greatest I must say! All of my concerns were dealt with and most of all he did his best to make sure I was happy with the decision. The respect and hard work he did for me will never go unnoticed.
To obtain a conviction under VTL § 1198(7)(b), prosecutors must prove each element of the offense beyond a reasonable doubt. Based on the statute, the core elements are:
If any one of these three elements is missing, the prosecution cannot obtain a conviction under this statute. Each element must be proven beyond a reasonable doubt, and a skilled defense attorney will examine all three for weaknesses in the evidence.
The knowledge element is often the most contested part of a § 1198(7)(b) case. Prosecutors can establish knowledge through direct or circumstantial evidence, such as:
Consider this example: Jane was convicted of DWI, and her driving privilege is now restricted to vehicles equipped with an ignition interlock device. Her brother Mike lets her borrow his car, which does not have an ignition interlock device installed. Mike was present in court when the IID requirement was imposed. Jane is later pulled over for a broken taillight, and the officer learns that she is restricted to operating IID-equipped vehicles even though the car she is driving is not so equipped. In that situation, Mike could face a charge under VTL § 1198(7)(b) based on evidence that he knew about Jane’s restriction, and Jane could face a charge under VTL § 1198(9)(d) for operating a vehicle without the required device.
A violation of VTL § 1198(7)(b) is an unclassified misdemeanor in New York. Although it is not considered a felony offense, a conviction can still carry serious criminal penalties.
Potential consequences may include:
In some cases, a conviction may also lead to collateral consequences affecting employment opportunities, professional licensing, and insurance rates. The penalties imposed will depend on the facts of the case, the defendant’s criminal history, and whether other alcohol-related offenses are involved.

Being charged with interlock device bypassing under VTL § 1198(7)(b) does not guarantee a conviction. There are several defenses you can raise, both procedural and substantive.
The most common defense is a lack of knowledge. If you did not know the driver was restricted to operating only IID-equipped vehicles, the prosecution may not be able to prove the mental-state element required by the statute. VTL § 1198(7)(b) also requires the restricted driver to notify a person who rents, leases, or loans a vehicle to them of the restriction.
For example, if Jane never told Mike about her IID restriction, Mike could argue he did not knowingly lend a vehicle to a restricted driver. The prosecution must prove Mike knew about the restriction; it is not enough to show only that Jane was subject to it. Knowledge, however, may be inferred from the surrounding facts, such as prior discussions, court attendance, or other evidence showing awareness of the restriction.
Another defense is that you did not actually rent, lease, or lend the vehicle. If the restricted driver took the vehicle without your permission, that may negate the lending requirement under the statute.
A mistake of fact may be a defense if it undermines the prosecution’s claim that you acted knowingly under VTL § 1198(7)(b). For example, if you reasonably believed the vehicle was equipped with a functioning ignition interlock device when you lent it, that mistake may support the argument that you did not knowingly provide a non-equipped vehicle.
This defense is fact-specific and has limits. The defendant would need to show that the belief was genuinely held and reasonable under the circumstances.
In rare cases, a defendant may try to raise a justification or emergency-based defense. New York recognizes justification defenses generally under Penal Law Article 35, but whether such a defense applies would depend heavily on the specific facts and would likely be limited to unusual circumstances.
If you are charged under VTL § 1198(7)(b) in Suffolk County, the case may be handled in Suffolk County District Court or in a local town or village justice court, depending on where the charge is filed. Suffolk County District Court has criminal jurisdiction over misdemeanors, and arraignment is the stage at which the defendant is told the charges, advised of the right to counsel, and asked to enter a plea.
Because ignition interlock requirements are part of New York’s broader Leandra’s Law framework, these cases are typically handled as part of the state’s enforcement of court-ordered IID restrictions.
If you have been charged under VTL § 1198(7)(b), do not discuss the facts of the case with police beyond providing basic identifying information. Preserve any text messages, emails, or other communications that may bear on whether you knew about the driver’s IID restriction, and make sure you attend all court dates. Failing to appear can result in a warrant or other consequences in the case.
A DWI defense attorney can evaluate whether the prosecution can actually prove the knowledge element required by the statute and whether some records or communications support your defense. VTL § 1198(7)(b) specifically requires proof that the vehicle was knowingly rented, leased, or lent to a person known to be restricted to IID-equipped vehicles.
Key Takeaway: Suffolk County courts handle VTL § 1198(7)(b) cases as part of their broader DWI enforcement. Family members, friends, employers, and rental agents are the most commonly charged parties. If you are charged, do not discuss the case with the police, preserve evidence, and contact a defense attorney immediately.
