IMPAIRED DUI DWI DRUNK DRIVING IN NEW YORK
Incidence of Impaired Driving
For one of every 110 miles driven in New York in 2000, a person with a blood alcohol concentration (BAC) >.10 sat behind the wheel. Police in New York reported 10,182 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 66,290 crashes in New York involved alcohol which killed 419 and injured an estimated 23,100 people.
Impaired Driving by Blood Alcohol Concentration (BAC)
In 2000, New York drivers with:
· BACs of .10 and above were involved in an estimated 63,100 crashes that killed 293 and injured 20,200
· BACs between .08-.09 were involved in an estimated 1,090 crashes that killed 37 and injured 900
· Positive BACs below .08 were involved in an estimated 2,100 crashes that killed 89 and injured 2,000
Alcohol is a factor in 11% of New York's crash costs. Alcohol-related crashes in New York cost the public an estimated $5.1 billion in 2000, including $2.2 billion in monetary costs and almost $2.9 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 $3.1 billion of the alcohol-related crash bill.
Costs per Alcohol-Related Injury
The average alcohol-related fatality in New York costs $5.5 million:
· $1.5 million in monetary costs
· $4.0 million in quality of life losses
The estimated cost per injured survivor of an alcohol-related crash averaged $156,000:
· $70,000 in monetary costs
· $86,000 in quality of life losses
Costs per Mile Driven
Crash costs in New York averaged:
· $7.90 per mile driven at BACs of .10 and above
· $3.40 per mile driven at BACs between .08-.09
· $0.20 per mile driven at BACs of .00
Costs per Drink
The societal costs of alcohol-related crashes in New York averaged $0.70 per drink consumed. People other than the drinking driver paid $0.40 per drink.
Impact on Auto Insurance Rates
Alcohol-related crashes accounted for an estimated 21% of New York's auto insurance payments. Reducing alcohol-related crashes by 10% would save $90 million in claims payments and loss adjustment expenses.
Prevention Savings of Impaired Driving Measures
New York already has many important impaired driving laws. They are saving money and lives. The estimates that follow describe the expected costs and savings, given New York's prices and impaired driving rates. The estimates assume New York's laws achieve average U.S. effectiveness levels.
Zero Tolerance Law: Laws like New York'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, this law costs approximately $90 and yields net savings of $2,000. 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.
Minimum Legal Drinking Age (MLDA): To reduce alcohol-related fatal crashes among youth, New York has adopted a MLDA of 21. It saves an estimated $1,500 per youthful driver. The loss of liquor sales is the large majority of the $450 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 New York's prices, if other proven impaired driving prevention measures were widely implemented in New York.
Sobriety Checkpoint Program: Intensive enforcement of New York State BAC limits with highly visible sobriety checkpoints typically would reduce alcohol-related fatalities by at least 15% and save approximately $171,600 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 $24,300.
Administrative License Revocation: A law that allows police or driver licensing authorities in New York to revoke a driver's license swiftly and automatically for refusing or failing a BAC test can reduce alcohol-related fatalities by 6.5% on average and save an estimated $148,400 per driver sanctioned. The value of the driver's lost mobility would be a large portion of the estimated $7,400 cost per driver sanctioned. Reinstatement fees assessed to offenders typically cover start-up and operating costs.
.08 BAC Law: A well-publicized State law lowering driver BAC limits to .08 can potentially reduce alcohol-related fatalities by an average of 7%. On average, a .08 law in New York would save an estimated $113 per licensed driver. The value of mobility losses and alcohol sales reductions resulting from the law are the large majority of the estimated $8 cost per licensed 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%. If implemented, savings could amount to an estimated $1,400 per youthful driver in New York. The value of the mobility lost by youth would be a large portion of the estimated $190 cost per youthful driver.
Enforcing Serving Intoxicated Patrons Law: Using undercover police officers to enforce the State 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 $0.80 per licensed driver and save about $60 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 $190 per licensed driver and saves about $600 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 New York approximately $2,200 and save on average $11,300.
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 $21,900 per vehicle equipped. Including equipment and case management costs, interlock costs would total approximately $2,630 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 New York. Per person arrested, the program would cost nearly $3,900 and could avoid an estimated $14,300 in crash costs and almost $4,940 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 New York could decrease recidivism by an estimated 48%, causing DUI crashes to decrease by 4%. Typically, per person arrested, this program costs approximately $3,300 and can avoid an estimated $16,000 in crash costs and $1,390 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: New York'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 73% of impaired driving fatalities in New York. The law saves an estimated $12,700 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 $770 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 23% of child fatalities in New York, and those seated in the back seat without proper restraints account for an additional 43% of child fatalities. Drinking drivers are more likely than other drivers to transport children improperly. Traveling in a child safety seat reduces the chance of a crash death by an estimated 71% for infants and 54% for children age 1-4. Child safety seat laws like New York'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 $4,500 in injury costs.
Motorcycle Helmet Use Law: Statewide, 8% of alcohol-related crash fatalities are motorcyclists; 35% of these motorcyclists were unhelmeted. The motorcycle helmet use law in New York 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 $590 in New York and prevent nearly $10,000 in injury costs.
