Delaware imposes separate suspensions for chemical test refusal and DUI conviction — each with different waiting periods before you can apply for a Conditional License. Most drivers don't realize both suspensions run concurrently, and the longer wait period controls your eligibility date.
Delaware Runs Two Separate Suspensions for Refusal Cases
When you refuse a chemical test in Delaware, the Division of Motor Vehicles issues an administrative suspension under 21 Del. C. § 2742 immediately — separate from any criminal DUI charge. This administrative suspension begins the day DMV receives notice of your refusal, not your conviction date.
If you are later convicted of DUI, the court imposes a second suspension. Both suspensions run concurrently, but they carry different lengths and different waiting periods before Conditional License eligibility. The administrative refusal suspension is typically longer than the conviction-based suspension for a first offense, which means the refusal suspension controls your reinstatement timeline.
You cannot apply for a Conditional License until you satisfy the hard suspension period of whichever suspension is longer. For first-offense refusal combined with first-offense DUI, the refusal suspension determines when you become eligible.
Administrative Refusal Suspension Length and Hard Wait Period
Delaware's administrative suspension for chemical test refusal lasts 12 months for a first refusal. During the first 90 days of this suspension, you are not eligible to apply for any form of restricted driving privilege — this is the hard suspension period.
After 90 days, you may apply for a Conditional License through the Delaware DMV. The Conditional License is not automatic. You must submit proof of enrollment in an approved DUI education program, an SR-22 insurance certificate, and documentation of your essential driving need — typically employment, medical appointments, or court-ordered obligations.
If you refuse a second time within 10 years, the administrative suspension extends to 24 months with no Conditional License eligibility at any point during that period. Delaware does not offer hardship relief for second-refusal cases.

Criminal DUI Suspension Runs Concurrently but May Be Shorter
A first-offense DUI conviction in Delaware triggers a separate 12-month license revocation under the same statute. However, the court-ordered suspension typically allows Conditional License eligibility after a shorter hard period — often as early as 30 to 60 days, depending on your BAC level and whether you completed the DUI program.
Because both suspensions run at the same time, you serve whichever waiting period is longer. In refusal cases, the administrative suspension's 90-day hard period usually controls. You cannot shortcut the administrative hard period by satisfying the criminal suspension's requirements — DMV treats them as independent tracks with independent eligibility clocks.
Once you pass the 90-day administrative hard period and satisfy the criminal court's requirements, you can apply for the Conditional License. The license remains valid through the remainder of both suspensions as long as you comply with all restrictions.
Ignition Interlock Device Is Required for All DUI Conditional Licenses
Delaware requires an ignition interlock device (IID) on any vehicle you drive under a Conditional License issued for a DUI-related suspension. The IID requirement begins the day your Conditional License is issued and continues for the full duration of the suspension — typically 12 months for first-offense DUI.
You must install the device with a state-approved vendor before DMV will issue the Conditional License. Installation costs range from $70 to $150, with monthly monitoring fees of $60 to $90. You are responsible for all costs.
If you violate the IID requirement by driving a non-equipped vehicle, attempting to bypass the device, or failing monthly calibration appointments, DMV will revoke your Conditional License immediately and restart your hard suspension period from zero.
SR-22 Filing Is Required for the Full Suspension Period
Delaware requires an SR-22 certificate of financial responsibility for all DUI-related suspensions, including refusal cases. The SR-22 filing must remain active for the full suspension period — 12 months for first-offense DUI, 24 months for second-offense DUI.
Your insurance carrier files the SR-22 directly with DMV on your behalf. If your carrier does not offer SR-22 filing, you will need to switch to a carrier that does. Most standard carriers in Delaware file SR-22 at no additional cost beyond the premium increase your DUI conviction triggers. That increase is typically $800 to $1,400 per year for first-offense DUI drivers.
If you do not currently own a vehicle, you can satisfy the SR-22 requirement with a non-owner SR-22 policy. This policy provides liability coverage when you drive a vehicle you do not own and satisfies Delaware's financial responsibility filing requirement. Premiums for non-owner SR-22 policies typically range from $40 to $80 per month.
Total Cost to Obtain and Maintain a Conditional License
The total cost to obtain a Conditional License in Delaware after a DUI refusal includes the application fee, IID installation and monitoring, SR-22 insurance, and program enrollment. The DMV Conditional License application fee is $143.75, which includes the reinstatement fee.
IID costs add $70 to $150 for installation and $60 to $90 per month for monitoring — approximately $720 to $1,080 over 12 months. SR-22 insurance premium increases add $800 to $1,400 annually. DUI education program enrollment costs $200 to $400 depending on the provider.
Total first-year cost: $1,933 to $3,023. If your suspension extends beyond 12 months or you face a second offense, IID monitoring and SR-22 filing continue and increase total cost proportionally.
