How Much Does a First-Offense OUI Cost in Maine?

The True Cost Is Far More Than the Fine

When people think about the cost of a first-offense OUI in Maine, they usually think of the court fine. The mandatory minimum fine is $500, and while that is not trivial, it represents only a fraction of the total financial impact. The real cost — including administrative fees, mandatory programs, insurance increases, and potential interlock expenses — typically runs between $3,400 and $6,500.

Here is a complete breakdown of where the money goes.

Immediate Post-Arrest Costs

The expenses start the night of the arrest:

• Towing and impoundment: $150–$300, depending on how far the tow truck travels and how long the vehicle stays in the lot
• Bail commissioner fee: $60

These costs are often paid before you even understand the full scope of what you are facing.

Court Fines and Surcharges

The criminal court imposes several charges upon conviction:

• Mandatory minimum fine: $500 ($600 if you refused the chemical test)
• State surcharge: 20% of the fine — $100 on a $500 fine
• Court fee: $65

Subtotal: $665 for test-takers, $785 for refusals

Judges have discretion to impose fines up to the Class D maximum of $2,000, but for a clean first offense with no aggravating factors, the mandatory minimum is typical.

DEEP Program Costs

The Driver Education and Evaluation Programs course is mandatory for reinstatement:

• Adult Risk Reduction course (21+): $300
• Under-21 program: $225
• Credit card processing fee: $10

If your screening during the course results in a referral for a clinical substance use evaluation, that evaluation is billed separately by the private provider — typically $150–$300. If the evaluation leads to mandated treatment, those sessions add additional costs that vary by provider and duration.

Subtotal: $310–$610+

BMV Administrative Fees

• Reinstatement fee: $50
• Driving record copy (for hearing preparation): $5–$10

Subtotal: $55–$60

Ignition Interlock Costs (If You Choose This Pathway)

The IID is optional for first offenses, but it is the most flexible path back to full driving. If you choose it:

• BMV petition fee: $50
• Device installation: $75–$150
• Monthly lease and monitoring: $60–$90 per month for approximately 4 months ($240–$360)
• Removal fee: $50–$100

Subtotal: $415–$660

Drivers who demonstrate financial hardship (household income below federal poverty guidelines) qualify for a 50% reduction on all vendor costs under state law.

Insurance Premium Increases

This is where the long-term cost really accumulates. A first-offense OUI conviction will increase your auto insurance premiums significantly. While Maine does not require SR-22 filing for a standard first offense, insurers will reclassify you as a high-risk driver.

• Average annual premium increase: $1,266–$3,900 depending on your insurer and driving history
• Duration of elevated rates: Typically 3–5 years

That insurance line is already one of the largest pieces of the $3,400–$6,500 total impact. Elevated rates can persist for several years after the conviction, so the longer-run cost can exceed the first-year increase.

Total Financial Impact

Adding it all together for a standard first offense where you chose the interlock pathway:

A typical first-offense OUI in Maine lands in the $3,400 to $6,500 range once you include the insurance impact and the mix of fees in a given case. The direct costs — fines, fees, DEEP, interlock — run $1,655 to $2,355 without counting legal representation.

Legal Representation Costs

If you hire a private defense attorney, expect a flat fee starting around $2,000 for standard first-offense representation. Attorneys who specialize in OUI defense or handle cases with aggravating factors may charge more.

Indigent defendants may qualify for court-appointed counsel through the Maine Commission on Public Defense Services. Eligibility is based on strict financial guidelines assessed by the court.

Where the Money Goes Matters

The cost breakdown above is not just an accounting exercise — it informs the decisions you need to make at each step of the process. Understanding whether to pursue the interlock or work-restricted pathway, when to enroll in DEEP, and how to prepare for the BMV hearing are all decisions with financial consequences.
