District of Columbia DUI Crash Statistics

IMPAIRED DUI DWI DRUNK DRIVING IN THE DISTRICT OF COLUMBIA

Incidence of Impaired Driving

For one of every 50 miles driven in the District of Columbia in 1999, a person with a blood alcohol concentration (BAC) >.08 sat behind the wheel. Police in the District of Columbia reported 3,500 crashes involving a driver or pedestrian with a BAC of .01 or more. Formulas developed by NHTSA were used to estimate the number of alcohol-related crashes where alcohol involvement was not reported by the police. An estimated total of 5,400 crashes in the District of Columbia involved alcohol which killed 38 and injured an estimated 1,800 people.

Impaired Driving by Blood Alcohol Concentration (BAC)

In 1999, the District of Columbia drivers with:

· BACs of .10 and above were involved in an estimated 5,100 crashes that killed 22 and injured 1,600

· BACs between .08-.09 were involved in an estimated 90 crashes that killed 5 and injured 100

· Positive BACs below .08 were involved in an estimated 200 crashes that killed 11 and injured 200

Costs

Alcohol is a factor in 54% of the District of Columbia's crash costs. Alcohol-related crashes in the District of Columbia cost the public an estimated $0.4 billion in 1999, including $0.2 billion in monetary costs and almost $0.2 billion in quality of life losses. (For definitions of the cost categories, see the definitions fact sheet.) Alcohol-related crashes are deadlier and more serious than other crashes. People other than the drinking driver paid $0.3 billion of the alcohol-related crash bill.

Costs per Alcohol-Related Injury

The average alcohol-related fatality in the District of Columbia costs $4.8 million:

· $1.6 million in monetary costs

· $3.2 million in quality of life losses

The estimated cost per injured survivor of an alcohol-related crash averaged $130,000:

· $64,000 in monetary costs

· $66,000 in quality of life losses

Costs per Mile Driven

Crash costs in the District of Columbia averaged:

· $21.20 per mile driven at BACs of .10 and above

· $9.20 per mile driven at BACs between .08-.09

· $0.40 per mile driven at BACs of .00

Costs per Drink

The societal costs of alcohol-related crashes in the District of Columbia averaged $0.90 per drink consumed. People other than the drinking driver paid $0.60 per drink.

Impact on Auto Insurance Rates

Alcohol-related crashes accounted for an estimated 22% of the District of Columbia's auto insurance payments. Reducing alcohol-related crashes by 10% would save $1 million in claims payments and loss adjustment expenses.

Prevention Savings of Impaired Driving Measures

The District of Columbia already has many important impaired driving law. They are saving money and lives. The estimates that follow describe the expected costs and savings, given the District of Columbia's prices and impaired driving rates. The estimates assume the District of Columbia's laws achieve average U.S. effectiveness levels.

Administrative License Revocation: Laws that allow police or driver licensing authorities to revoke a driver's license swiftly and automatically for refusing or failing a BAC test have reduced alcohol-related fatalities by 6.5% on average and saved an estimated $92,900 per driver sanctioned. The value of the driver's lost mobility is the large majority of the estimated $4,600 cost per driver sanctioned. Reinstatement fees assessed to offenders typically cover start-up and operating costs.

Zero Tolerance Law: Laws like the District of Columbia's that make it illegal for persons under 21 to drive with a positive BAC have reduced impaired-driving fatalities by 4% on average. Per licensed youth driver, these laws cost approximately $50 and yield net savings of $1,300. Medical care cost savings alone exceed the intervention cost. The primary cost is the value of mobility lost by youth who are forced to reduce their drinking or driving.

.08 BAC Law: A well-publicized law lowering driver BAC limits to .08 can potentially reduce alcohol-related fatalities by an average of 7%. On average, the District of Columbia's .08 law saves an estimated $71 per licensed driver. The value of mobility losses and alcohol sales reductions resulting from the law are the large majority of the estimated $5 cost per licensed driver.

Intensive Sobriety Checkpoint Program: Intensive enforcement of the District of Columbia BAC limits with highly visible sobriety checkpoints reduce alcohol-related fatalities by at least 15% and save approximately $107,400 per checkpoint. Including police resources, costs of travel delay and the value of mobility losses by impaired drivers apprehended and sanctioned, the costs of conducting a checkpoint average about $15,200.

Minimum Legal Drinking Age (MLDA): To reduce alcohol-related fatal crashes among youth, the District of Columbia has adopted a MLDA of 21. It saves an estimated $900 per youthful driver. The loss of liquor sales is the large majority of the $280 cost per youthful driver.

Graduated Licensing: Graduated licensing is a three-stage program that involves a learner's permit, intermediate (provisional) license, and full licensure. To advance between stages, young drivers are required to demonstrate responsible driving behavior. Graduated licensing with a midnight curfew could reduce youth fatalities by at least 5% and total alcohol-related fatalities by 2%. Savings amount to and an estimated $900 per youthful driver in the District of Columbia. The value of the mobility lost by youth is the large majority of the estimated $120 cost per youthful driver.

Potential Savings from Further Prevention Efforts

A number of additional strategies can mitigate the harm from impaired driving. The following paragraphs estimate the potential savings, in the District of Columbia's prices, if other proven impaired driving prevention measures were widely implemented in the District of Columbia.

Enforcing Serving Intoxicated Patrons Law: Using undercover police officers to enforce the District's law against serving alcohol to intoxicated bar and restaurant patrons would reduce alcohol-related crash fatalities by an estimated 11%. It would cost an estimated $0.50 per licensed driver and save about $40 per licensed driver.

Server Training: Server training programs provide education and training to servers of alcoholic beverages with the goal of altering their serving practices to prevent patron intoxication and alcohol-impaired driving. Generally, 40% to 60% of intoxicated patrons drive after consuming alcohol in bars, clubs or restaurants. A statewide, full-day, mandatory, face-to-face server training program with active management support has the potential to reduce nighttime DUI injury crashes by 17%. Implementing such a program costs an estimated $120 per licensed driver and saves about $400 in crash costs per licensed driver.

Interventions Targeting Repeat Offenders

Not many repeat offenders are deterred by broad impaired driving laws. Four alternative sanctioning approaches have proven especially effective at reducing repeat offenses.

Automobile Impoundment: Impounding vehicles after conviction for DUI or driving while suspended can decrease recidivism by an estimated 38% and DUI crashes by about 4%. Overall, per vehicle impounded, enforcement of this law would cost the District of Columbia approximately $1,400 and save on average $7,100.

Ignition Interlock: Breathtesting ignition interlocks are designed to prevent anyone with a positive BAC from starting or driving a car. Attaching an interlock to a car for a year after its operator is convicted of driving while intoxicated would reduce recidivism by an estimated 75% and alcohol-related fatalities by 7%. It would save almost $13,700 per vehicle equipped. Including equipment and case management costs, interlock costs would total approximately $1,650 per vehicle.

Electronically Monitored House Arrest: Electronic monitoring is an alternative to incarcerating repeat offenders. It provides assurance of an offender's presence within an assigned area. Monitoring programs attach a device to the wrist or ankle that relays a continuous signal to a computer and also may require offenders to relay a breath test when prompted by a random phone call. Implementation of this program could decrease recidivism by an estimated 31%, causing DUI crashes to decrease by about 3% in the District of Columbia. Per person arrested, the program would cost nearly $2,400 and could avoid an estimated $9,000 in crash costs and almost $3,070 in incarceration costs.

Intensive Probation Supervision with Treatment: Intensive probation supervision with treatment is an alternative to incarcerating repeat offenders. This early intervention program seeks to reduce alcohol-impaired driving by addressing repeat offenders' drinking habits and provides intensive individual counseling and monitoring. Implementation of this program in the District of Columbia could decrease recidivism by an estimated 48%, causing DUI crashes to decrease by 4%. Typically, per person arrested, this program costs approximately $2,100 and can avoid an estimated $10,000 in crash costs and $860 in incarceration costs.

Prevention Savings of Occupant Protection Measures

Along with impaired driving interventions, a number of important occupant protection strategies reduce impaired driving and other highway injuries.

Primary Safety Belt Law: The District of Columbia's primary safety belt law allows law enforcement to stop and ticket a driver for nonuse of a safety belt without requiring the driver to be cited for or have committed another offense. Unbelted occupants account for 85% of impaired driving fatalities in the District of Columbia. The law saves an estimated $7,960 per new belt user. If enforced with frequent belt use checkpoints, the value of temporary discomfort experienced by some new belt wearers and travel delay costs at checkpoints are the large majority of the law's estimated $483 cost per new belt user.

Child Safety Seat Law: Infants and children who are seated in places other than the back seat account for nearly 34% of child fatalities in the District of Columbia, and those seated in the back seat without proper restraints account for an additional 32% of child fatalities. Drinking drivers are more likely than other drivers to transport children improperly. Traveling in a child seat reduces the chance of a crash death by an estimated 71% for infants and 54% for children aged 1-4. Child safety seat laws like the District of Columbia's typically reduce occupant fatalities of children age 4 and under by approximately 15% and their alcohol-involved deaths by a similar amount. The average child seat costs approximately $45 but avoids nearly $2,800 in injury costs.

Motorcycle Helmet Use Law: Statewide, 10% of alcohol-related crash fatalities are motorcyclists; 68% of these motorcyclists were unhelmeted. The motorcycle helmet use law in the District of Columbia saves lives and prevents devastating and debilitating head injuries. Wearing a motorcycle helmet reduces a rider's risk of death by 29% and nonfatal injury risk by 15%. On average, helmets cost about $370 in the District of Columbia and prevent nearly $6,200 in injury costs.
