Under Lockdown, Californians Consume More Alcohol and Drive Differently: Orange County Residents Most Likely to be Penalized for a DUI

Drivers in Orange County are most likely to be penalized for a DUI violation, but the consequences for reckless driving differ widely across county lines in California.

While many California residents shelter in place, state highways have seen dramatic shifts in driving behavior. Traffic on some California interstates has declined by as much as 65%. But while fewer cars populate the roads, more people than expected have been arrested for speeding and for driving under the influence during the day time. As a result, ValuePenguin analyzed DUI penalty trends across California counties.

Between March 19 and April 19 of 2020, the California Highway Patrol issued nearly 2,500 citations to drivers who were speeding at over 100 mph. That represents an 87% increase from the same period in 2019.

Why are those figures so significant? The volume of traffic has decreased during the last year, but the number of speeding incidents, traffic arrests and DUI's have not decreased at the same rates.

At the same time, some California residents are increasing their alcohol consumption. The San Francisco Chronicle reports that Bay Area residents are drinking 42% more than before. With a state-wide ease on the restriction of alcohol sales, customers can now pick up alcohol with a takeout order or get alcohol delivered to their homes. Despite restrictions on to-go containers, driving under the influence is a concern.

We define penalization as being found guilty of a violation. Nonpenalization includes having a case dismissed, being found not guilty or having the court withhold adjudication. Convictions are divided by the total number of arrests to calculate a penalization rate.

Plus, according to data from the California Department of Motor Vehicles (DMV), being arrested for a DUI can lead to very different penalties depending on where you live. ValuePenguin also found that the rate at which drivers are convicted for this violation varies greatly by county, ranging as high as 86% in Orange County and as low as 52% in Kings County.



Key findings:

1. Drivers in Orange County are most likely to be penalized for DUI-related traffic violations. Other counties where drivers were most likely to be penalized included Marin, Ventura, Sacramento and Placer counties.

2. Conversely, drivers in Kings, Alameda, Madera, San Bernardino and Merced counties have the lowest penalization rates for DUI-related offenses in the state.

3. Some counties — including Lake, Shasta and Sacramento — convicted drivers of a felony more often than as a misdemeanor for DUI, and drivers in Alameda, Colusa and Madera counties were most likely to be found guilty on charges of reckless driving.

4. Counties vary drastically in terms of how quickly they adjudicate. Madera County residents wait an average of 313 days between a violation and conviction, which is more than double the state average of 119 days.

What are the consequences of driving under the influence?

California drivers with a blood alcohol content (BAC) level of 0.08% or higher may face severe legal repercussions. Consequences may include substantial fines, license suspension or revocation, jail or prison time, probation, community service and more.

Additionally, motorists with a DUI conviction are likely to pay substantially higher car insurance costs in California due to the increased risk associated with their driving records.

These are the legal ramifications of a first, second, third and fourth offense for driving while intoxicated in California.

First offense

For the first DUI conviction, an offender may be required to

  • Fines up to $3,600, plus additional penalty fees in some cases
  • Up to six months in jail
  • Driver's license is surrendered for at least four months
  • Three months of DUI school
  • Three- to five-year DUI probation

Second offense

For the second DUI conviction, an offender may be required to

  • Up to one year in jail
  • 18 to 30 months of DUI school
  • Fines up to $4,000
  • Driver's license is surrendered for up to two years
  • Ignition interlock device must be installed on your car
  • Three- to five-year DUI probation

Third offense

For the third DUI conviction, an offender may be required to

  • Up to one year in jail or up to 16 months in prison
  • Fines up to $18,000
  • Driver's license is surrendered for up to three years
  • 30 months of DUI school
  • Ignition interlock device must be installed on your car
  • Three- to five-year DUI probation

Drivers with a DUI conviction may also be required to carry SR-22 insurance until the state restores driving privileges.

Methodology

DUI arrest and conviction data from 2006–2016 in California was collected from the California Department of Motor Vehicles (DMV). Counties were only included in the analysis for a given violation if they had at least 100 convictions in the most recent year for which data was available.

We apply the term "penalization" when the violation was categorized by the California DMV as a misdemeanor DUI, felony DUI or reckless-driving conviction. We define "no penalty" as an instance when there was no record of any conviction associated with the arrest.
