The Dangers of Drunk Driving | Boca Recovery Center

The dangers of drunk driving include loss of life, physical injuries, legal penalties, revocation of one’s driver’s license, and severe emotional and psychological consequences.

Struggling with Addiction? Get Help Now

Driving while intoxicated is a serious offense with grave repercussions. Thousands of people are killed or wounded in drunk driving collisions each year. In fact, 13,384 people lost their lives in a drunk driving accident in the U.S. in 2021, averaging out to about one person every 39 minutes.[1]

The statistics surrounding drunk driving are staggering, with numerous studies showing that driving under the influence dramatically increases the likelihood of being involved in a severe or fatal crash. While alcohol use disorder (AUD) is certainly a driving force behind the problem, binge drinking, and alcohol abuse also contribute to drunk and buzzed driving accidents. 

Drunk Driving Statistics

These statistics highlight the scope of drunk driving in the U.S.:

  • The cost of drunk driving deaths amounted to more than $123 billion in 2020. This included a cost estimate for the lives lost as well as medical expenses.[2]
  • In 2020, 229 children were killed in car crashes related to alcohol consumption.[3]
  • Every year, approximately 1 million people are arrested for drunk driving.[2]
  • About 31% of car crashes involve drivers with a BAC of at least 0.08%.[1] 

Understanding Blood Alcohol Content Levels & Driving

Different levels of blood alcohol content (BAC) have effects on your driving abilities. Even low levels of alcohol in the system can significantly alter cognitive processing and reaction times enough to render the driver incapable of driving safely. 

Here is what to expect from different BAC percentages:[1]

0.02%–0.03% BAC

At this level, the drinker may feel a gentle wave of relaxation, and their eyesight may blur or become slightly unfocused. Decision-making skills are usually still sharp, and most people can handle multiple tasks at the same time.

0.05%–0.06% BAC

With a higher BAC, drinkers are usually still relaxed, although their attention span decreases, and their reaction times slow. Coordination and tracking skills start to suffer. Handling the steering wheel and hitting the brakes will require a bit more effort.

0.08% BAC

This is the legal limit for driving in the U.S. for people 21 and up. If your BAC is at this level, you cannot drive.

At this level, reasoning, concentration, and reaction times are significantly impaired. Drivers may experience reduced judgment, decreased perception, and impaired control over their vehicle.

0.1%–.12% BAC

At this stage, substantial impairment of motor skills occurs. Coordination becomes difficult, and balance is affected, leading to more severe difficulties controlling the vehicle.

0.15% BAC & Higher

At these high levels, individuals may exhibit severe impairment. They will likely have blurred vision, slowed information processing, and weakened muscle control. Decision-making abilities and reaction times are significantly compromised, making driving extremely dangerous.

What Are the Dangers of Drunk Driving?

Everyone’s tolerance to alcohol is different, and even those who drink regularly can find that their tolerance and ability to function while drinking can shift significantly. It’s never safe to drive after drinking. Here are some of the associated dangers:[1-5]

Loss of Life

In 2021, more than 13,300 people died in accidents related to drunk driving. This includes drunk drivers, passengers, people in other vehicles on the road, and pedestrians. All of these deaths are wholly preventable.  


People involved in drunk driving accidents may survive, but they are often severely injured. Permanent and long-term injuries occur frequently, including paralysis and traumatic brain injury. Some people require lifetime care. 

Legal Penalties

Driving under the influence (DUI) comes with severe legal penalties, including high fines and jail time, depending on the severity of the charge. If you kill someone while driving drunk, you will likely be charged with gross vehicular manslaughter, which is a felony. A first-time DUI with no associated crash can cost drivers more than $10,000 in legal fees and fines.

Losing Driver’s License

A DUI may result in revocation of your driver’s license. The duration of this will depend on the severity of the charge and whether it is a repeat offense. Losing your driver’s license may make it difficult to get to work and maintain other areas of your life. A DUI will also cause your insurance rates to spike. 

Mandatory DUI Education Courses

If you are convicted of a DUI, you may need to complete a DUI education course that covers dangers of drunk driving and substance abuse. The standard length of the course will vary by state. For example, in California, a first-time DUI conviction will require a 30-hour alcohol and drug counseling program that takes place over three months. Courses for repeat offenders are usually much longer and more intensive.

Emotional & Psychological Consequences

Survivors of drunk driving accidents and their loved ones bear a heavy burden of trauma, grief, and a profound sense of loss. Post-traumatic stress, anxiety, and shattered trust often persist, making it difficult to find solace and move forward. The consequences of impaired driving extend far beyond the physical.

Repeated DUIs

People who drink and drive often find themselves caught in a cycle of repeat DUIs or DWIs (driving while under the influence or intoxicated). According to National Highway Traffic Safety Administration, almost a third of people arrested for DWI are repeat offenders.[6]

Some people underestimate their level of impairment and overestimate their ability to drive safely. Despite the known risks of drunk driving, they rationalize that they aren’t that drunk. These drivers often don’t think they are taking any risk.[7] 

People struggling with alcohol use disorder (AUD) are resistant to traditional deterrents to drunk driving, such as public health messages, police enforcement, sanctions, and educational programs aimed at deterring and addressing their behavior. They need comprehensive treatment for AUD to stop the cycle.

Is Drunk Driving a Sign of Addiction?

Drunk driving is often a sign of alcohol abuse or addiction, specifically AUD. When someone consistently gets behind the wheel while under the influence, it illustrates a troubled relationship with alcohol.  

Other signs of AUD, or alcohol addiction, include the following:[8-10]

  • Regular pattern of risk-taking behavior: Regularly taking the risk of driving under the influence reveals a lack of control and demonstrates that it’s not a one-off problem.
  • Increased tolerance: Needing to consume larger amounts of alcohol to achieve the desired intoxication level is a sign of developing tolerance, which can be an indicator of alcohol use disorder.
  • Failed attempts to quit or cut down: Persistent efforts to stop or reduce alcohol consumption but being unable to do so successfully is a warning sign of addiction and an indication that professional help is needed.
  • Obsession with alcohol: Obsessive thoughts about alcohol, making plans around whether or not alcohol will be involved, and an overwhelming desire to drink despite negative consequences are indications of potential addiction. 
  • Prioritizing alcohol above all else: Neglecting responsibilities in favor of alcohol use is a sign of addiction. This includes instances where individuals choose to drive under the influence despite knowing the potential risks and legal consequences.

What Is Alcohol Use Disorder?

AUD is a complex condition where alcohol use is compulsive.[8] Despite the consequences that alcohol use brings to health, relationships, and life in general, the urge to drink persists. Someone with AUD will continue to drink despite negative results piling up in their life. 

AUD is a chronic condition, and there is no cure, but the condition can be effectively treated and managed.

Signs and symptoms of AUD include the following:[8,11-12]

  • Cravings or a strong desire to consume alcohol
  • Difficulty controlling or limiting alcohol intake
  • Continued drinking despite negative consequences or harmful effects on personal, social, or professional life
  • Developing a tolerance to alcohol, requiring increasing amounts to achieve the desired effects
  • Experiencing withdrawal symptoms when attempting to cut down or quit drinking
  • Spending a significant amount of time obtaining, consuming, or recovering from alcohol use
  • Neglecting or reducing participation in important activities and interests due to alcohol
  • Persistent desire or unsuccessful attempts to quit or cut back on alcohol
  • Continued alcohol use even when it leads to physical or psychological problems
