PennDOT Form DL-21SCR: Ignition Interlock Removal Guide – If you are required to use an ignition interlock system in Pennsylvania and need to remove the device from a vehicle you will not operate during your required interlock period, you must complete PennDOT Form DL-21SCR. This official self-certification form allows approved vendors to legally remove the ignition interlock system from vehicles that are not part of the ones you have chosen to drive.
What Is PennDOT Form DL-21SCR?
Form DL-21SCR is the official Pennsylvania Department of Transportation (PennDOT) document titled “Self-Certification of Vehicle(s) to Be Operated Requesting Removal of Ignition Interlock System(s) from Vehicle(s) Not Operated.”
It is used when an individual under an ignition interlock restriction wants the interlock device removed from one or more vehicles that they do not intend to operate during the mandatory one-year interlock period. The form certifies which vehicles the driver will operate (those that must remain equipped with the interlock) and authorizes removal from the others.
The form (revision 8-17) must be completed accurately. Misstatement of facts is a misdemeanor of the third degree under 18 Pa. C.S. Section 4904(b), punishable by a fine of up to $2,500 and/or imprisonment of up to one year.

Who Needs to File Form DL-21SCR?
You need this form if:
- You are subject to Pennsylvania’s ignition interlock requirement (typically for DUI-related suspensions or chemical test refusals).
- An ignition interlock system has already been installed on more than one vehicle.
- You have designated specific vehicle(s) that you will operate during the required interlock period.
- You want the interlock device removed from other vehicle(s) that you will not operate.
Pennsylvania law generally requires an ignition interlock on every vehicle you own, operate, or lease during the restriction period. However, once you certify the specific vehicles you will drive, the device may be removed from others using this form.
This form is different from Form DL-21SC (Self-Certification of Vehicle(s) to Be Operated or Inoperable), which is used at the beginning of the interlock process.
How to Complete PennDOT Form DL-21SCR?
Print or type all information in blue or black ink. The form has four main sections:
Section A – Driver Information
Provide your full name, complete residential address (a P.O. Box may be added but cannot be the only address), and Pennsylvania driver’s license number. Your driver number appears on your suspension/revocation notice or restoration requirements letter. You can also obtain it by calling PennDOT Customer Care at 717-412-5300 or visiting the official website.
Section B – Vehicle Information
List all vehicles you will operate during the interlock period. Include:
- Plate (tag) number
- Title number
- Vehicle Identification Number (VIN)
- Year and make
This information is found on your vehicle registration card. You must be prepared to show valid registration and proof of motor vehicle insurance. For additional vehicles, attach a separate listing.
Section C – Statement of Vehicle(s) to Be Operated
Print your full name and sign the statement confirming that you will only operate the vehicle(s) listed in Section B. Date the form. This is your formal self-certification.
Section D – Statement of the Vendor
Do not complete this section yourself. After the interlock system is removed from the non-operated vehicle(s), the approved ignition interlock vendor completes Section D. The vendor lists the installation date of the interlock system on the vehicles in Section B, prints their name, signs, and dates the form. Only authorized vendor employees may complete this section.
How to Submit Form DL-21SCR?
Follow these steps:
- Complete Sections A, B, and C accurately.
- Present the completed form to an approved Pennsylvania ignition interlock vendor when requesting removal of the device from the non-operated vehicle(s).
- After removal, the vendor completes Section D.
- The vendor emails the fully completed form to PennDOT at [email protected].
The form is submitted electronically by the vendor. Keep a copy for your records.
