Averting Alcohol-Impaired Driving Deaths: Strategies For Safer Roads

Alcohol-impaired driving is a leading cause of traffic-related deaths in the United States, with 13,524 people killed in 2022. Despite progress in reducing alcohol-related crashes, stagnating fatality rates indicate that new approaches are needed to accelerate progress and save lives. Interventions typically focus on deterring driving after drinking, rather than reducing drinking itself. Strategies to decrease alcohol-impaired driving deaths include increasing alcohol taxes, regulating alcohol outlet density, implementing sobriety checkpoints, ignition interlocks, and addressing alcohol use disorders. High-visibility enforcement and minimum drinking age laws have also contributed to reduced alcohol-related deaths.

Implement policies that make alcohol less accessible, available, and affordable

Implementing policies that make alcohol less accessible, available, and affordable is a crucial strategy in reducing alcohol-impaired driving deaths. Here are several approaches that can be taken to achieve this:

Increase Alcohol Taxes:

One effective way to reduce alcohol consumption and related harms is to increase taxes on alcohol. Research has shown that higher prices lead to decreased consumption, particularly among vulnerable and high-risk groups. For example, a 2017 study found that an increase in alcohol sales tax in Maryland led to a significant reduction in alcohol-positive drivers aged 15-20 and 21-34. Similarly, Utah's reduction of the legal BAC limit to 0.05, along with stricter enforcement, resulted in fewer impaired drivers and a decrease in crash and fatality rates.

Regulate Alcohol Outlet Density:

Limiting the number of retailers that can sell alcohol in a particular location can help reduce alcohol accessibility. This strategy has been effective in various locations, including New Mexico, where a ban on drive-through alcohol sales led to a decreasing trend in alcohol-related crashes.

Enhance Treatment Accessibility:

Improving access to treatment services for alcohol use disorders is essential. This includes making services more affordable, especially for groups with low socioeconomic status. By addressing the root causes of harmful alcohol consumption, we can reduce the likelihood of alcohol-impaired driving.

Public Awareness and Education:

Implementing comprehensive public awareness and education campaigns can play a vital role in reducing alcohol-impaired driving. These campaigns can target specific audiences, such as young people, and be conducted during relevant times, like holiday seasons. Additionally, providing accurate information about the full range of alcohol-related harms and effective preventive measures can empower individuals to make informed choices and reduce alcohol consumption.

Address Youth-Targeted Products:

Special attention should be given to products that are designed to appeal to youth, such as powdered alcohol. Policies banning the sale of these products or expanding the definition of alcohol in existing laws to include them can help reduce youth access to alcohol and, consequently, decrease the risk of alcohol-impaired driving among younger individuals.

Increase taxes on alcohol

Alcohol-impaired driving is a leading cause of traffic-related deaths in the United States. To reduce the number of alcohol-impaired driving fatalities, one effective strategy is to increase taxes on alcohol. This approach is based on the fundamental economic principle that the quantity demanded of a product is inversely related to its price.

Raising alcohol taxes can lead to a decrease in alcohol consumption, as higher prices act as a deterrent for consumers. This relationship between price and consumption is supported by studies that found a 10% increase in alcohol prices resulted in a 3% to 10% decrease in alcohol consumption. Specifically, research in Maryland showed that increasing the sales tax on alcohol from 6% to 9% led to a significant 12% reduction in alcohol-positive drivers aged 15-20 and 21-34. However, it is important to note that the rate of alcohol-positive drivers aged 55 and above increased, possibly due to their higher disposable income and decreased price sensitivity.

The effectiveness of increasing alcohol taxes in reducing impaired driving is also evident in the studies that examined the relationship between alcohol prices, taxes, and motor vehicle crashes. These studies consistently found a significant association between higher alcohol prices and taxes and a decrease in injuries and deaths due to alcohol-related crashes. Additionally, the impact of increased alcohol taxes extends beyond road safety. Research suggests that higher alcohol taxes can reduce excessive alcohol consumption, leading to a decrease in various alcohol-related harms, including unintentional injuries, violence, and liver cirrhosis.

While raising alcohol taxes can be an effective strategy, it is important to recognize that taxes represent a relatively small proportion of the total purchase price of alcoholic beverages. Therefore, a substantial increase in taxes may be necessary to achieve a noticeable reduction in alcohol consumption and impaired driving. Nonetheless, the additional costs of collecting these taxes are relatively small, as the infrastructure for tax collection is already in place.

In summary, increasing taxes on alcohol is a viable strategy to reduce alcohol-impaired driving deaths. By making alcohol less affordable, consumption decreases, and consequently, the likelihood of impaired driving and related crashes is reduced. However, it is important to carefully consider the magnitude of tax increases and complement this strategy with other effective interventions to maximize the impact on road safety and public health.

Impose ignition interlocks for all people convicted of alcohol-impaired driving

Alcohol-impaired driving is a leading cause of traffic-related deaths in the United States, with about 30% of all traffic crash fatalities involving drunk drivers. In 2023, there were 12,429 people killed in these preventable crashes. Among children (aged 14 and younger) killed in motor vehicle crashes, a quarter were killed in drunk-driving crashes. Clearly, this is a pressing issue that needs to be addressed.

One effective strategy to reduce alcohol-impaired driving deaths is to impose ignition interlocks for all people convicted of alcohol-impaired driving, including first-time offenders. An alcohol ignition interlock is a breath-test device connected to a vehicle's ignition system. It measures the alcohol content in the breath of the driver and prevents the vehicle from starting if the motorist's blood alcohol concentration (BAC) is above a pre-set limit, typically 0.02 g/dL.

Ignition interlocks are highly effective in preventing repeat offences while installed, reducing them by about 70%. Laws requiring ignition interlocks for all offenders were associated with a 26% reduction in alcohol-impaired drivers (with BACs of 0.08 g/dL) in fatal crashes from 2001 to 2019, compared to periods with no interlock law. For repeat and high-BAC offenders, interlock laws led to a 20% decrease in alcohol-impaired drivers in fatal crashes over the same period.

To strengthen state alcohol ignition interlock programs, several key features can be implemented. These include regular training for interlock program managers, law enforcement, vendors, DMV, and court staff; maintaining excellent data records on offenders; and combining annual data from all agencies to effectively monitor, report, and evaluate program effectiveness.

In addition to preventing repeat offences, ignition interlocks can be used as an opportunity to address underlying alcohol use disorders. Incorporating assessment and treatment for alcohol use disorder into interlock programs has shown promise in reducing repeat offences even after the interlocks are removed. This suggests that, in the long term, ignition interlocks may not only deter repeat offences but also help address the root cause of alcohol-impaired driving.

Increase the number of sobriety checkpoints

Sobriety checkpoints are stops conducted by police officers at specific, highly visible locations to check drivers for impairment. When implemented fully, these checkpoints are well-publicized, highly visible, and conducted regularly. The goal of sobriety checkpoints is to increase the perceived likelihood of being caught driving while impaired, thereby reducing the incidence of impaired driving.

Research has shown that sobriety checkpoints are effective in reducing crashes and crash fatalities involving alcohol-impaired drivers. One study found that rates of impaired driving were significantly lower in states that conducted sobriety checkpoints. This relationship remained consistent even after controlling for binge drinking. Furthermore, the size and duration of the checkpoints do not seem to affect their effectiveness. Smaller checkpoints staffed by fewer officers for shorter periods can have a similar impact as larger checkpoints with more officers for longer durations. This is because the presence of a checkpoint, regardless of its scale, affects the perceived risks of detection and punishment for motorists.

To optimize the effectiveness of sobriety checkpoints, high enforcement and publicity are crucial. Combining checkpoints with mass media campaigns can increase awareness about the dangers of drinking and driving. Motorists who are made aware of checkpoints through various channels are less likely to drive while impaired in the future. Conducting a larger number of checkpoints at different locations and times can also help maximize the impact of such programs.

Sobriety checkpoints have been in use since the 1930s, with some countries allowing all drivers who are stopped to be given a breath test. In the United States, the constitutionality of sobriety checkpoints has been questioned due to potential violations of Fourth Amendment protections. However, the benefits of sobriety checkpoints in reducing alcohol-impaired driving and saving lives cannot be overlooked.

In conclusion, increasing the number of sobriety checkpoints, along with effective publicity and enforcement, can be a powerful strategy to decrease the amount of alcohol-impaired driving deaths.

Focus on reducing drinking to the point of impairment

While interventions to reduce alcohol-impaired driving have largely focused on deterring drunk driving, less attention has been paid to reducing drinking to the point of impairment. This is an important and underutilized strategy to reduce alcohol-impaired driving fatalities. Here are some ways to focus on reducing drinking to the point of impairment:

Implement effective drinking-oriented policies

Despite the increase in driving-oriented policies, the implementation of effective drinking-oriented policies has remained relatively unchanged over the past two decades. Drinking-oriented interventions refer to policies, programs, systems, and strategies that aim to reduce drinking to the point of impairment. These interventions have been shown to independently reduce impaired driving and alcohol-impaired driving crashes. Examples of such interventions include responsible beverage service (RBS) and social host liability laws. RBS has been studied as a potential intervention to reduce excessive drinking and subsequent impaired driving. Social host liability laws have been associated with significant reductions in alcohol-related traffic fatalities and drinking after drinking.

Reduce alcohol accessibility, availability, and affordability

Making alcohol less accessible, available, and affordable can effectively reduce drinking to impairment and prevent alcohol-impaired driving. This can be achieved by increasing taxes on alcohol and regulating the number of retailers that can sell alcohol in a particular location. For example, an increase in alcohol sales tax in Maryland led to a significant reduction in alcohol-positive drivers aged 15-20 and 21-34 years. Similarly, a ban on drive-through alcohol sales in New Mexico resulted in a decreasing trend of alcohol-related crashes.

Public awareness campaigns

Public awareness campaigns can play a crucial role in educating people about the dangers of drinking and driving, as well as promoting responsible drinking. NHTSA, for instance, is committed to eliminating drunk driving through research and public awareness campaigns. Similarly, publicizing sobriety checkpoints and high-visibility saturation patrols can deter people from driving while impaired.

Address alcohol use disorder

Alcohol use disorder (AUD) is a serious issue that requires long-term, tailored, and specialized treatment programs. By incorporating AUD assessment and treatment into interlock programs, the rate of repeat offenses can be reduced even after interlocks are removed. Additionally, individuals with AUD should ideally receive treatment before committing an alcohol-impaired driving offense.

Reduce alcohol marketing exposure

Alcohol marketing has been identified as an important point of intervention, especially for underage persons. There is a positive relationship between alcohol advertising and motor vehicle crash fatalities, and young people are particularly vulnerable to the influence of alcohol marketing. By reducing exposure to alcohol marketing, alcohol consumption and, subsequently, alcohol-impaired driving can be decreased.
