The parking garage next to the Mount Vernon courthouse has been closed to the public since March 2024, after inspectors found buckling floors and separating ramparts. GPS still routes people straight to it. Defendants show up for a court date, find the garage barricaded, and end up circling downtown Mount Vernon for street parking with a two-hour limit that may not cover the length of a docket call, which is exactly how someone ends up with a failure-to-appear warrant on top of an OVI charge.
Getting the car back only happens on weekdays
The Mount Vernon Police Department runs its impound lot at 500 North Elm Street on a strict release schedule: 8 a.m. to 4 p.m., Monday through Friday, no exceptions for holidays and no weekend hours at all. Get arrested Friday evening and the vehicle is effectively locked up until Monday morning, guaranteeing at least three days of storage fees (Friday, Saturday, Sunday) no matter how quickly you're able to pay. If you left medication, keys, or a phone inside, MVPD will sometimes send an officer to the lot outside business hours for essential-item retrieval, but it's entirely discretionary and depends on whether patrol has anyone free that night.
Which statute governs the tow matters for how the release notice works. A stop on a public road falls under state law requiring the agency to search ownership records within five business days and mail a notice to the last known address; the vehicle gets classified as a nuisance and processed for disposal if unclaimed within ten days, which is a real risk for anyone held in custody or inpatient treatment longer than that. A vehicle towed off private property, like a bar parking lot, follows a different statute and can be released with just a "drop fee" if the owner shows up before the tow actually starts. Private towing contractors are required by law to accept both cash and major credit cards and to hand over a receipt showing what was charged and what was paid; keep that receipt, since it matters if a restitution question ever comes up in court.
Bond is easier now than it used to be
Knox County installed a bond kiosk at the jail in 2024, and it changed the math meaningfully: family or a bail agent can post bond directly at the jail 24 hours a day, without waiting on the Clerk of Courts to open. Before the kiosk, a Friday-evening bond meant sitting in custody until Monday regardless of ability to pay; now the kiosk processes it on the spot, for a transaction fee around $3.45 in cash, more by card. The Mount Vernon Municipal Court maintains a standing bond schedule for standard misdemeanor OVI charges, letting the jail release someone without a judge's hearing at all, though a felony OVI or a case involving an accident still requires an arraignment first.
Once booked, a $20 inmate processing fee gets pulled straight from whatever a family member deposits into the commissary account, so a $50 deposit effectively becomes $30 the moment it lands. A basic mat rental runs another $10. Non-emergency medical care carries its own co-pays: $10 for a sick call, $10 for the dental clinic, $5 for a medical assessment, plus a $5 handling fee and 10 cents per pill for over-the-counter medication. For someone who knows they're about to turn themselves in, handling anything non-urgent beforehand avoids feeding money into that system.
Visitation is almost entirely digital now, run through video terminals in the jail lobby (free, but scheduled in advance) or from a personal device at home for a fee around $5.99 per half hour. It runs seven days a week, generally 9 a.m. to 10 p.m., with occasional blackouts for headcount or meals.
Court, and the two paths a plea takes you down
Mount Vernon Municipal Court sits at 5 North Gay Street, third floor, open weekdays 8 a.m. to 4 p.m., under Judge John C. Thatcher. Security includes a metal detector at the entrance, and phones have to be off or silenced; a device going off or being used during a hearing can be confiscated on the spot. A not-guilty plea moves the case into a pretrial phase for discovery and negotiation. Recent sentencing patterns show a typical structure of 180 days of jail time with the bulk of it, often around 177 days, suspended contingent on completing probation, with fines commonly running $500 to $1,000 for a first or second offense before court costs. For defendants dealing with an underlying mental health or substance use issue, the court also runs a Mental Health Court and a MERIT drug court docket, both requiring a program coordinator's screening and the judge's sign-off to enter.
License reinstatement means a trip to Columbus
The suspension takes effect immediately on a refused or failed test, and it's a separate track from the criminal case, typically appealed at the initial arraignment. Full reinstatement requires serving out the suspension period (anywhere from 6 months to 3 years), completing an 8-hour remedial driving course, and filing an SR-22 high-risk insurance bond that has to stay active for 3 to 5 years, since a lapse triggers an automatic re-suspension.
There's no full-service BMV reinstatement center in Knox County. The nearest one sits in Columbus, about 59 miles and an hour's drive away, which creates the obvious problem of needing to drive somewhere to restore the right to drive. Reinstatement fees run $475 or more depending on prior offenses. Drivers who can show enrollment in SNAP, Medicaid, or SSDI, or whose offense predates September 15, 2020, may qualify for the state's amnesty program, which can reduce or waive those fees entirely through Form BMV 2829.
Ignition interlock: one local option
Intoxalock runs a service location right in Mount Vernon, at 18201 Coshocton Road, which matters because monthly calibration visits are mandatory and driving out of county to reach one could itself violate a limited-privileges license. Installation runs roughly $30 to $115 depending on the setup, with a monthly lease between about $55 and $116, plus a calibration fee near $20 every 30 to 90 days. Over a full year, that adds up to somewhere between $1,000 and $1,500, on top of everything else the case already costs.
