A zero tolerance law for alcohol is a law that completely prohibits the consumption or possession of alcohol in various settings. Common applications include DUI laws, school policies, and workplace policies.

What Does the Zero Tolerance Law State?

Federal Laws and Policies

Zero tolerance laws were introduced to the federal sentencing structure in the 1980s as a direct result of the War on Drugs. These laws were created in an attempt to deter drug use and ease the caseload on federal courts.

The use of zero tolerance laws spread following the Columbine shooting in 1999 when two students at Columbine High School brought firearms to school with the intent to kill, resulting in the death of 12 students, one teacher, and themselves. Public outcry brought attention to the lack of national anti-violence policies in federal courts.

Although zero tolerance policies had been considered and enacted outside of the purpose of violence and drug use prevention, these two events are the foundation of zero tolerance laws and led to their widespread use today.

Federally, zero tolerance laws are particularly strict with respect to firearms. Possession, sale, transport, and theft of firearms are all heavily regulated.

Federal law disallows the possession of firearms by an individual if any one of the following criteria are met:

  • The individual has been convicted in any US court for any crime with a sentence exceeding one year
  • The individual is an active fugitive from justice
  • The individual is verifiably addicted to any controlled substance
  • The individual has been convicted of an offense against a family member, intimate partner, or household member within the past 5 years
  • The individual is subject to a court order that:
    1. Is currently active
    2. Has not been acknowledged
    3. Restrains the individual from harassing, stalking, assaulting, or otherwise threatening the petitioner of the court order or some other named individual
    4. Specifically requires the individual to relinquish possession of any firearms

The above also applies to anyone who wishes to sell or transport firearms. Additionally, those who plan to sell or transport firearms must be properly licensed to do so. The transportation or sale of stolen firearms or firearm ammunition is punishable by a fine, at minimum, and up to 10 years in prison, provided the individual is aware the firearm is stolen. Other prohibitors of firearm use include:

Zero tolerance policies are increasingly common in schools as well. Stemming from policies intended to deter weapons in schools, zero tolerance policies in the education system have extended to all facets of discipline, including student interpersonal conflict, vandalism, and drugs.

The Gun-Free Schools Act, a federal law applying to any state that receives federal funding, requires local educational boards to enforce a mandatory minimum punishment of one-year expulsion for the possession of a firearm on school property. This act follows the logic of "broken windows" theory, which argues that controlling smaller, highly visible crimes will prevent larger and more damaging crimes; for example, arresting the perpetrators who broke a window may help prevent other crimes such as robberies in the area.

Applying zero tolerance policies elsewhere is up to the discretion of each state and school system, but many have chosen to apply minimum punishments of suspension and expulsion to offenses such as:

Policies that are applied broadly rarely escape criticism, and zero tolerance policies are no exception. Common criticisms of these policies include:

  • Lack of scientific evidence of effectiveness
  • Disproportionate punishment
  • Supporting the school-to-prison pipeline
  • Favoring speed of resolution and punishment over rehabilitation
  • Painting broad strokes over issues that should be judged on a case-by-case basis

Criticisms of the use of zero tolerance policies in schools are the most prolific due to their direct impact on the criminal justice system. Criticisms include:

Zero tolerance is a structure used in policies and laws that requires specific, predetermined outcomes for wrongdoings. Within the criminal justice system, zero tolerance is often applied to drug, gun, and immigration offenses. Zero tolerance policies are present within the education system and the workplace as well, usually applying to both illegal and non-lawbreaking offenses. Criticisms aimed at zero tolerance policies usually point to the lack of evidence to support their efficacy, an increase in negative outcomes, and lack of consideration for each individual case.

Additional Info

Zero Tolerance

You've probably heard about 'zero tolerance' before. You may even know someone who was suspended or expelled from school as a result of these policies. Maybe it was fair that they received the punishment. Then again, maybe not.

Zero tolerance is rooted in a strong stance based on public opinion towards a specific type of crime or infraction, and it mandates a specified course of action for those infractions. It may take the form of state or federal laws with pre-defined penalties, known as mandatory minimum sentences, or policies in the workplace or school system with strict, outlined consequences for violations.

Zero Tolerance Laws: State and Federal

The vast majority of criminal laws that use the framework of zero tolerance are written regarding driving a vehicle under the influence of alcohol and/or drugs. In some states, these laws have been applied or written to include non-motorized vehicles, such as golf carts and bicycles.

Other terms that may be used and that vary by state for these crimes are:

  • DUI: Driving Under the Influence
  • DWI: Driving While Intoxicated
  • OWI: Operating (a motor vehicle) While Intoxicated
  • OUI: Operating (a motor vehicle) Under the Influence

In contrast, most federal zero tolerance laws are in relation to the possession, sale, transport, or theft of guns and rifles. If a convicted felon is found to have a firearm, it is considered a serious crime, particularly if the crimes the individual was convicted of are violent crimes. These crimes generally warrant a minimum sentence of ten years imprisonment or more in some cases.

Zero Tolerance Policies in the Workplace

Employers who utilize zero tolerance policies have deemed specific violations so serious that they are not forgivable, and generally warrant immediate dismissal of the employee. These policies may include termination for:

  • Arriving to work drunk or high
  • Operating a vehicle on behalf of the company while drunk or high
  • Doing drugs or drinking alcohol on company premises
  • Awarding raises or promotions based on bribes or sexual favors
  • Sexual assault of a coworker
  • Theft
  • Disclosure, theft, sale, or other improper handling of protected or confidential information of clients and/or employees

If it is found that an employee did break these rules, there is often some form of investigation conducted within the company first, followed by the termination of the employee.

Zero Tolerance Policies in Education

Many public and private schools have zero tolerance policies. These policies are generally regarding the behavior and actions of students while on school grounds. Fighting on school grounds in many districts may be cause for suspension and/or expulsion, based on these policies. Threatening the lives of students, teachers, and/or school administrators may also be cause for expulsion based on zero tolerance. Bringing or making drugs, drug paraphernalia, weapons, weapon accessories, explosive devices or other specified items onto school grounds may also warrant enforcement of the policies. Private schools may enforce even more rules with zero tolerance for infractions as a result of their exclusive enrollment policies.

Criticisms of Zero Tolerance

With any policy there are criticisms of its application, especially when the policy is applied to situations that it was clearly not designed to handle. A few examples of this would be:

  • A student being expelled for bringing Tylenol to school in Maine;
  • A man arrested for driving a golf cart while intoxicated in California;
  • A South Carolina student suspended for using the term gun on social media in reference to a fictional story about a dinosaur.
