Driving Under the Influence vs. Drowsy Driving

California roads are constantly active, with drivers navigating them at all hours. Often, these drivers may be experiencing fatigue or may have consumed alcohol or drugs. While both driving under the influence (DUI) under California Vehicle Code Section 23152 and driving while drowsy can lead to dangerous driving and potential legal consequences, California law distinguishes between these situations significantly. For anyone seeking to understand their rights and responsibilities while driving, it is crucial to seek legal advice from a skilled DUI defense lawyer to grasp the differences between DUI and drowsy driving.

What Constitutes Drowsy Driving?

Drowsy driving occurs when someone operates a vehicle while feeling excessively tired or sleepy. Unlike DUI, there isn't a specific statute in the California Vehicle Code that explicitly defines or prohibits driving while drowsy. However, legal concern arises when this fatigue results in unsafe driving behaviors. These behaviors can include drifting between lanes, ignoring traffic signals, veering off the road, or any other actions that indicate a lack of control over the vehicle. Law enforcement officers may stop a driver if they suspect the driver is not operating the vehicle safely. It's important to note that the symptoms of drowsy driving can sometimes be mistaken for those of alcohol or drugs, such as red eyes, slow reactions, and impaired coordination.

Legal Status of Drowsy Driving in California

Even though California law doesn't have a specific "drowsy driving" offense, a driver who causes an accident or drives unsafely due to fatigue can still face legal repercussions. The law typically addresses such situations under broader statutes.

• Reckless Driving. California Vehicle Code Section 23103 VC defines reckless driving as operating a vehicle with a "willful or wanton disregard for the safety of persons or property." A driver who is severely fatigued and exhibits dangerous driving patterns like swerving, speeding, or other unsafe actions could be charged with reckless driving under this section. While the law doesn't explicitly mention drowsiness, the dangerous driving that can result from fatigue can lead to these charges.
• Vehicular Manslaughter. In more severe cases where a drowsy driver causes a fatal accident, prosecutors will thoroughly investigate the driver's actions. Although there isn't a charge specifically labeled "drowsy driving manslaughter," a driver's fatigue is often a significant factor when considering charges like vehicular manslaughter under California Penal Code Section 192(c) PC. This statute applies when a driver's negligence leads to the death of another person. A drowsy driver who fails to drive with reasonable caution could be deemed negligent or grossly negligent, depending on the severity of their actions, and could face charges for causing a fatal collision.
• Civil Liability. Drowsy drivers can also be held civilly liable if their fatigue results in a traffic accident. Under California's negligence laws, any driver whose negligent behavior causes injury or property damage to another person can be held financially responsible for medical bills, property repair costs, lost income, and other related expenses. This applies even if no criminal charges are filed. Victims or their insurance companies can pursue civil lawsuits to seek compensation.

Driving Under the Influence and Its Legal Consequences

Driving under the influence (DUI) is a clearly defined criminal offense in California. California Vehicle Code Section 23152 VC states that it is illegal for anyone to drive a vehicle while under the influence of alcohol, drugs, or a combination of both. This includes prescription and over-the-counter medications, as well as illegal substances, if they impair the driver's mental or physical abilities.

The law also establishes specific blood alcohol concentration (BAC) limits. For non-commercial drivers, it is generally illegal to drive with a BAC of 0.08% or higher. Commercial drivers face a stricter limit of 0.04%, and drivers under 21 can be penalized for a BAC of 0.01% or higher due to California's Zero Tolerance Law.

A person arrested for DUI under Section 23152 faces both criminal charges in court and administrative actions by the California Department of Motor Vehicles (DMV), which can independently suspend or revoke their driver's license.

In more serious DUI cases, particularly those involving injury or death, certain Penal Code sections become relevant. For example, if an impaired driver causes injury, they could be charged under Penal Code Section 191.5(a) PC (gross vehicular manslaughter while intoxicated) or Penal Code Section 192(c) PC (vehicular manslaughter), depending on the specifics of the case. Prosecutors typically consider factors like prior DUI convictions, the driver's BAC level, their driving behavior, and the severity of any injuries or fatalities when deciding whether to file misdemeanor or felony DUI charges. Felony DUI convictions can result in significant prison sentences, sometimes three years or more for each person injured if great bodily injury enhancements apply.

• California Vehicle Code Section 23152 VC: This section explicitly prohibits driving under the influence of alcohol or drugs or with a BAC of 0.08% or higher (or other specified limits).
• California Penal Code Section 191.5(a) PC (Gross Vehicular Manslaughter While Intoxicated): This felony offense applies when a person driving under the influence commits an act, other than the driving itself, which is a misdemeanor or infraction, or is lawful but done with gross negligence, and as a result, another person is killed.
• California Penal Code Section 192(c) PC (Vehicular Manslaughter): As mentioned earlier, this section covers the killing of a human being without malice aforethought in the driving of a vehicle. It can be charged as either a misdemeanor or a felony, and intoxication can be a factor in determining negligence.

Standard Jury Instructions for DUI Cases

California's jury instructions for DUI cases, known as CALCRIM instructions, outline the elements the prosecution must prove beyond a reasonable doubt to secure a conviction. Specifically, CALCRIM 2110 provides instructions on the elements of driving under the influence:

CALCRIM 2110: Driving Under the Influence (Veh. Code, § 23152(a), (f), (g)): This instruction states that the prosecution must prove:

• The defendant drove a vehicle.
• When the defendant drove, they were under the influence of an alcoholic beverage, a drug, or both, OR their blood alcohol content was 0.08 percent or more at the time of the test.
• The instruction also defines "under the influence" as having impaired mental or physical abilities to the extent that the person can no longer drive with the caution of a sober person using ordinary care under similar circumstances. The jury is instructed that the manner of driving alone is not sufficient to determine impairment, but it is a factor to consider along with all other circumstances.

CALCRIM 2100: Driving a Vehicle or Operating a Vessel Under the Influence Causing Injury (Veh. Code, § 23153(a), (f), (g)): This instruction applies when someone is injured as a result of DUI. It requires proof that the defendant drove under the influence and committed an illegal act or was negligent while doing so, causing the injury.

CALCRIM 2111: Driving With a Blood Alcohol Level of 0.08 Percent or More (Veh. Code, § 23152(b)): This instruction focuses specifically on the offense of driving with a BAC at or above the legal limit.

Sentencing Components for a DUI Offense in Los Angeles

The sentencing for a DUI conviction in California can vary significantly based on the circumstances, including whether it's a first, second, third, or subsequent offense and whether there were any aggravating factors like injuries or fatalities.

First-Time DUI: Typically charged as a misdemeanor, a first DUI offense can include:

• Up to six months in county jail (though often less, with possibilities for work release or house arrest).
• Fines and penalty assessments totaling $1,500 to $2,000 or more.
• Completion of a DUI education program lasting three to nine months, depending on the BAC level.
• A probation period of three to five years, with conditions to avoid new violations and comply with court orders.
• A driver's license suspension by the DMV for four months, which may run concurrently with any court-ordered suspension.

Second DUI Offense: Penalties escalate for a second DUI within ten years:

• Jail time ranges from 96 hours to one year.
• Higher fines.
• A longer DUI education program, up to 18 months.
• Extended license suspension or revocation.
• Mandatory installation of an ignition interlock device (IID).

Third DUI Offense: A third DUI within ten years carries even more severe consequences:

• Increased jail time.
• Higher fines.
• A DUI education program extending up to 30 months.
• Longer license suspension or revocation.
• Mandatory IID installation for a longer period.

Fourth or Subsequent DUI Offense: A fourth DUI within ten years can be charged as a felony, with potential penalties including:

• Up to three years in state prison.
• Significant fines.
• Lengthy driver's license revocation, potentially permanent.
• Other long-term consequences associated with a felony conviction.

DUI with Injury or Fatality: If a DUI results in injury or death, the penalties are substantially more severe, potentially including felony charges, lengthy state prison sentences, and significant fines. For instance, gross vehicular manslaughter while intoxicated under Penal Code Section 191.5(a) can carry a state prison sentence of up to ten years, and even more if there are multiple victims or other aggravating factors.

Comparing Drowsy Driving and Impaired Driving

While the outward signs of a fatigued driver and an impaired driver can sometimes appear similar, such as lane drifting, failure to notice signals, droopy eyes, slow reactions, and impaired coordination, the legal ramifications are vastly different. Law enforcement officers might initially mistake a tired driver for one under the influence due to these overlapping symptoms.

When an officer suspects impairment due to alcohol or drugs, they will typically conduct field sobriety tests (FSTs) and potentially a preliminary alcohol screening (PAS) test. Even if a driver claims to be merely fatigued, the officer may proceed with a DUI arrest based on poor driving or performance on FSTs. However, if subsequent breath or blood tests reveal a legal BAC or no drugs, the driver might avoid a DUI conviction but could still face charges for reckless driving if the officer believes their fatigue created dangerous driving conditions.

Defending Against DUI Allegations When Fatigue Is a Factor

If a driver is charged with DUI but believes fatigue or drowsy driving was the primary factor leading to the stop, a skilled defense attorney can challenge the prosecution's case. They might highlight the lack of chemical evidence of alcohol or drugs or question the reliability of the field sobriety tests, as fatigue can mimic signs of intoxication like red eyes, slowed reactions, and poor balance. An attorney can emphasize that factors such as lack of sleep, long work hours, or underlying medical conditions could explain the driver's appearance and behavior without indicating alcohol or drug use. Furthermore, if breath or blood tests show a legal BAC or no drugs, the defense can argue that the officer's initial suspicion of impairment was unfounded or that the reason for the traffic stop (like weaving) had a non-alcohol-related cause.

Why a Skilled Defense Lawyer Is Important

Whether facing a DUI charge or allegations of reckless driving due to drowsiness, it is crucial to consult with an experienced criminal defense attorney. DUI convictions carry severe penalties, including potential jail time, substantial fines, mandatory educational programs, and driver's license suspensions. Even a misdemeanor reckless driving conviction can have lasting consequences on a criminal record and lead to increased insurance rates.

At Kraut Law Group Criminal & DUI Lawyers, we can thoroughly review police reports, body camera footage, breathalyzer maintenance records, and any blood test data to identify potential errors in police procedures. Procedural mistakes, such as an unlawful traffic stop or flawed testing protocols, can provide grounds to challenge the evidence against you. When drowsiness, rather than alcohol or drugs, is the true explanation for driving behavior, a strong defense strategy can potentially lead to reduced charges or even a dismissal of the case.

Speak With a Los Angeles DUI Attorney

Every driver must recognize the serious risks associated with operating a vehicle while not fully alert and sober.
