What Are DUI Laws for Underage Drivers?

3.7% of licensed drivers in the United States are teenagers, but they have accident rates that are nearly three times higher than drivers aged 21 years and older. Drivers under the age of 21 are responsible for a substantial number of alcohol-related accidents.

DUI laws for underage individuals are much tougher than they are for those who are of legal age. A BAC of 0.08% is the accepted legal limit for legal drinkers. Many states take a lower BAC standard for drunk-related offenses happening among underage people.

DUI charges and heavy fines are meted out to minors who have been found to contain a trace of alcohol in their systems. Regulatory sanctions include license suspensions, fines, or the necessity of attending alcohol educational classes.

DUI laws differ across states. Under CT DUI laws, a teenage driver caught driving with a BAC at or above a certain level can have their license suspended immediately, get fined, be made to undergo mandatory alcohol education, and face criminal charges.

Let’s discuss the various applicable DUI laws for underage drivers.

Zero-Tolerance BAC Limits

Most states legislate that the minimum blood-alcohol content for drivers is 0.08 percent. This percentage requirement has been lowered by the state of Utah in Utah Code Section 41-6a-502 to 0.05 percent. The National Highway Systems Designation Act of 1995 introduced a zero-tolerance law for all individuals under 21 and made it enforceable if the limit is reached.

According to NHTSA, federal law requires states to enact a law establishing a blood alcohol concentration (BAC) of 0.02 percent for underage drivers in exchange for federal highway funds. All states eventually complied.

Every state has established its specific BAC limit. Many states set the limit at 0.02 percent. Other states establish a rule that bans any detectable alcohol presence. Arizona requires drivers under 21 to treat any alcohol presence as a legal violation based on Arizona Revised Statutes Section 4-244(34): The general population reaches a 0.02 percent BAC after consuming less than one complete alcoholic drink. The consumption of even tiny amounts of alcohol leads to potential criminal charges.

In most states an underage driver faces full DUI penalties when their BAC meets or exceeds the standard adult threshold, rather than receiving an underage zero-tolerance violation.

According to underage DUI lawyer Joshua S. Davidson, the penalties associated with this offense are severe and include mandatory jail time/community services, thousands of dollars in fines and court fees, driver’s license suspension, vehicle impoundment, and other expenses. A conviction also comes with significant lasting impacts on the convicted person’s life.

Implied Consent and Chemical Testing

According to FindLaw’s DUI legal guide, every state has implemented implied consent laws stating that drivers on public roads automatically consent to chemical testing if police have probable cause to believe they are intoxicated. 

Underage drivers must fulfill this requirement when police stop them on the road. California Highway Patrol officers must conduct preliminary alcohol screenings for drivers under 21 who are stopped according to California Vehicle Code Section 23136 while adult drivers have the choice to refuse the test.

Police officers can make arrests and bring additional charges against individuals who refuse to take chemical tests. Typically, refusal carries an additional and separate administrative penalty that can automatically suspend the driver’s license. Some states automatically suspend for a longer period for refusals to submit to a chemical test than for failure to pass the test, with the actual penalties depending on the state’s jurisdiction.

The Texas Transportation Code Section 724.035 establishes that first-time offenders who refuse testing will face a 180-day license suspension while second-time offenders will receive a two-year license suspension.

Refusing to take the test does not let a driver avoid a DUI. Refusal loads further fines and penalties on top of the DUI itself.

Administrative License Suspension

Most states separate the license suspension process from the criminal prosecution through administrative per se laws. A suspension begins automatically upon a failed chemical test or refusal. The license suspension is independent of any court proceeding. This procedure is handled through the state’s DMV rather than the criminal courts.

Most states give drivers only a short deadline, sometimes just days, to request an administrative hearing to contest the suspension. The suspension will become effective if the driver does not ask for a hearing to challenge it. Court proceedings in any administrative process and criminal case run separately. An outcome of one set of proceedings only has implications for the other.

First-offense zero-tolerance violations result in suspensions for underage drivers, which last between 30 days and even a year.

In some states, the driver will face extended suspension time or license revocation until they reach 21 years of age if their BAC result exceeds the adult threshold.

Criminal Penalties

States determine how to treat a zero-tolerance violation, which occurs at low BAC levels through criminal, civil, or administrative procedures. A minimal BAC underage violation operates in some states through the DMV suspension process, which does not create a conventional criminal conviction. 

The law in some jurisdictions classifies any underage drinking violation as a misdemeanor when the violator has a BAC level below the legal limit. Offenders face common penalties which include fines and required attendance at alcohol education classes and community service and probation.

The legal system punishes drivers with adult BAC levels through DUI penalties, which include mandatory jail time and extended driving suspensions and ignition interlock device installation and increased monetary penalties. 

The state law enforcement agencies impose harsher punishment for repeat offenders who face potential felony charges as a result of existing regulations and the particular facts of each case.

Long-Term Consequences

Underage DUI offenses lead to legal penalties that extend their effects beyond the immediate punishment. A conviction leads to permanent record existence, which shows up on background checks conducted by employers and landlords and professional licensing boards. 

College applications that require criminal conviction disclosure will show a DUI, which will impact school admissions, scholarship eligibility, and access to campus housing. Insurance companies use DUI offenses to increase rates, which usually leads to sharp premium increases. 

Military service eligibility and professional licensing may also be affected depending on the circumstances and the licensing board involved.

Record Sealing and Expungement

DUI offenders who are minors cannot have their records expunged until they have served and paid every related fine.

A motion for dismissal can only occur five years after the crime and under Section 1203.4 of the Penal Code against a first offender. The process does not provide true expungement since the record remains accessible in specific situations, which include future DUI sentencing.

In Texas, those charged under the Alcoholic Beverage Code may be eligible for expungement in limited circumstances depending on the case outcome, under Texas Code of Criminal Procedure Article 55.01. 

Any record relief granted still counts as a prior offense for sentencing purposes in any future DUI case.
