Hawaii has a large and growing problem with drunken driving. In 2012, authorities in Hawaii made 7,346 arrests for driving under the influence of alcohol, up 17% from 2006. Nearly 3% of Hawaiian adults surveyed said they had driven after drinking too much in the past 30 days, well above the national average of 1.9%, according to the Centers for Disease Control and Prevention. And for drivers who get a DUI in Hawaii, the ticket itself ins’t the only financial penalty.

Drivers in Hawaii caught driving under the influence face other steep financial consequences, including criminal charges, attorney fees, a likely fine and driver’s license suspension. But one of the biggest financial impacts of a DUI is the sharp increase in the cost of Hawaii car insurance, which can last for years.

On average, first-time offenders convicted of DUI in Hawaii can expect to see their car insurance premiums rise 76.6% to $1,765.80 a year, up from the statewide average of $999.85, according to a NerdWallet study.

Typically, the higher premium will be in place three years, although the period can range from 35 months to five years. In addition, first-time offenders caught with a blood alcohol content (BAC) of 0.08% or more can expect to pay a fine of $150 to $1,000, depending on location of the citation.

Key findings

Insurance costs go up. The average Hawaii driver will pay $765.95 more annually for car insurance after a DUI conviction. Over three years, this adds up to $2,297.85 in additional car insurance costs.

Least expensive island: Maui. The true cost of a DUI in Maui, the least expensive place, ranges from $2,961.25 to $4,131.25 on average, including fines and increased auto insurance premiums.

Most expensive island: Oahu. The true cost of a DUI in Oahu, the most expensive place, ranges from $3,408.79 to $4,578.79.

Search for insurance. Finding a carrier that has the shortest period of increases could lower total insurance costs. A DUI-related insurance increase can vary from 35 months to five years, depending on the carrier.

What are the costs associated with a DUI in Hawaii?

To calculate the “true cost” of a DUI conviction in Hawaii we looked at three costs:

The fine. For first time offenders with blood alcohol content (BAC) at 0.08% and higher, the fine can range from $150 to $1,000.

Ignition interlock device fees. Drivers convicted of DUI are required to have an ignition interlock device for the duration of their license revocation period, which is one year for first-time offenders. An ignition interlock device is a built-in Breathalyzer that prevents the driver from starting the car if it detects a BAC at 0.02% or higher. The device costs about $70 to $150 to install and $60 to $80 a month to monitor and calibrate. Over a year, the total costs can range from $790 to $1,110.

Insurance premium increases. Annual insurance premiums can increase dramatically after a DUI citation. The actual amount depends on location and driver, but on average, drivers can expect to pay $765.95 more on car insurance each year.

Our study doesn’t take into account other costs associated with a DUI arrest, including legal fees and time lost from work.

How can you minimize insurance costs after getting a DUI?

After getting a DUI, insurance carriers may raise car insurance rates or drop your coverage. If you’re not dropped, it may be a good time to shop for a new carrier. Insurance companies give different weighting to infractions like DUIs, so your current carrier may not be the cheapest.

Consider getting quotes from other insurance providers. Hawaii requires drivers convicted of DUIs to file SR-22 paperwork certifying that they have liability coverage, typically for three years after the conviction. In addition, convicted drivers should be sure to ask about discounts — including those for vehicle safety features and bundling policies — which may be available.

To calculate the true cost of a first-time DUI conviction, we accounted for the minimum and maximum fines mandated by Hawaii’s courts, ignition interlock fees and three years of insurance premium increases.

Actual DUI-related costs will vary from driver to driver.

To determine the average insurance premium increases, we calculated the average annual car insurance premium for drivers with clean records, then calculated the average car insurance premium for drivers who were convicted of a DUI with a BAC of 0.08%.

Estimated insurance costs are for illustrative purposes only. The actual insurance increases you face will vary depending on your insurance carrier, your location and other factors.
