What it costs in Harbeson
Interlock pricing is set at state level, so what applies in Harbeson applies across Delaware. Delaware caps these fees by regulation — a quote above them is not legal.
| Charge | Maximum allowed | What it covers |
|---|---|---|
| Installation | $100 | includes removal at the end of the program, and $30 of it is rebated back to you when the device comes out |
| Monthly | $75 | monitoring and calibration |
| Removal | No charge | covered by the installation fee |
State-capped maximum — a provider may not charge more · DE Admin. Code 2223 — Ignition Interlock Device Installation, Removal and Monthly Fees · effective 2022-03-11 · checked 2026-08-23
The fees nobody quotes you over the phone
These are charged on top of the three above, and they are where a cheap-looking Delaware quote turns expensive.

| Maximum initial payment (install + first month) | $175 |
What Delaware requires
Delaware runs two routes rather than one. At arraignment a driver with no prior DUI may elect the First Offender Program, which waives the right to a speedy trial and to an administrative hearing; those who took a chemical test may add the interlock election to it. There is also a separate voluntary program. Either way the interlock license waits until you meet the minimum qualifications.
- First offense: Set by the program you enter: Delaware runs a First Offense Election diversion with the device and a separate voluntary program, and the license is not issued until you meet the minimum qualifications
- Lockout threshold: Set by the device approved by the Director of the DMV; three program breaches add two months, five add four, eight add six
- Program run by: Delaware Division of Motor Vehicles, IID Unit
Why Delaware orders these devices
An interlock order is not a judgment about you personally — it is what the state does with every case of this kind, and the reason sits in the crash record.
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. The count covers fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. What the device changes is measurable too: a car fitted with one cannot be started over the limit, which is why the order attaches to driving privileges rather than to the sentence.

Interlock questions in Harbeson
Where can I get an ignition interlock device installed in Harbeson, DE?
We index 1 certified installation point in Harbeson, run by Smart Start. Addresses are listed above. Book with the provider your paperwork names, not the nearest one — a device approved in one state is not automatically approved in the next, and switching brands mid-term means a second installation fee.
How much does it cost to have an ignition interlock device installed in Delaware?
Delaware publishes its own figures rather than leaving it all to vendors: up to $100 to fit the device and up to $75 a month while it stays on the car, and the monthly figure is a ceiling an approved provider may not exceed. Removal is billed separately at the end of the term.
Can I drink one beer and still start the car in Delaware?
Almost certainly not. Delaware does not print one fixed number in the statute — the level is set by the certifying agency in the device standard, typically between 0.02% and 0.025% BAC, far below the 0.08% driving limit. The device is not testing whether you are impaired, it is testing whether you drank. One drink shortly before a test is enough on most programs, and the fail is recorded whether or not you try again.
What does an ignition interlock device do?
An ignition interlock is a breath-alcohol tester wired into your car ignition. You blow into it before starting the engine; if your breath alcohol is above the state threshold, the engine will not start.
While you are driving, the device asks for rolling retests at random intervals. Every sample, skipped test, and lockout is recorded and sent to the agency monitoring your case.
