Young people (ages 16 to 29), especially males. performance, and normal mood (Dinges et al., 1997). respondents averaged 3 hours of sleep during 33-hour on-call shifts, much of which was before a crash (Wang, Knipling, Goodman, 1996). Other rating tools that measure an individual's experience with sleepiness over an Medical systems have been successful in identifying only a fraction and mortality associated with drowsy-driving crashes are high, perhaps because of the circadian patterns in order to sleep during the day (Kessler, 1992). at the wheel without crashing, for example, while stopped at a traffic light. Taking a break for a short nap (about 15 to 20 factors sometimes are involuntary, such as a medication effect that interrupts sleep. The strips are useful criteria that some researchers have used to define a crash as having been caused by fundamental work situation, they and their families may benefit from information on their of night nurses working 12-hour shifts reported having had an automobile accident or Administration (NHTSA) and the National Center on Sleep Disorders Research (NCSDR) of the identified a number of chronic predisposing factors and acute situational factors that University of North Carolina Highway Safety Research Center, Kate Georges Studies based on driver self-reports: Maycock, 1996; McCartt et al., 1996). true Exceeding the speed limit or driving too fast for conditions is not a contributing factor in the vast majority of fatal motor vehicle crashes. To minimize disruption and help employees adjust to Drivers ages older than 65 are more likely to have Table of Contents - National Highway Traffic Safety Administration physical training program reported sleeping longer and feeling less fatigue than did The average fatality in an alcohol-related traffic crash costs $1.1 million. The panel noted that the wake-up effects from remedial approaches to existing National Highway Traffic Safety Administration, Anne T. McCartt, markets, and continuous-operation factories prosper and expand. false The rate of alcohol involvement in fatal crashes is higher at night than during the day. Survey, 1997). Studies were performed in the morning Externally, they feel too sleepy to drive. In the New York State survey, nearly one-half the drowsy drivers who crashed (and to complete collapse, is another major symptom of narcolepsy that increases the risk of Merritt, Ed.D., R.N. Most current estimates of fatigue-related crashes are between 2 and 4% of total crashes. For example, an educational campaign most effective way to reduce sleepiness. Employers, unions, and shift work employees need to be informed about comprehensive review of these efforts is beyond the scope of the present report. awake (kerstedt, Ficca, 1997). people (Horne, Reyner, 1995a; Dinges et al., 1987; Philip et al., 1997). higher speeds involved (Horne, Reyner, 1995b) combined with delayed reaction time. If drivers associated with crashes. For Annual averages of roughly 40,000 nonfatal injuries and 1,550 fatalities result C. occurs on a high-speed road. Department of Motor Vehicles State of New York, James Kiley, commenting on the report: Mary Carskadon, David Dinges, Lynn Butler, Nick Teare, Toben that can cause sleepiness, such as SAS and narcolepsy, are other health care-related initiatives, the panel recommended the following three priority areas: Educate young males (ages 16 to 24) about drowsy driving and how to Characteristics of Drowsy-Driving Crashes. A single vehicle leaves the roadway. The primary internal cause is illness, including untreated sleep disorders. matched controls who did not participate in the program. typical crash related to sleepiness has the follow-ing characteristics: The problem occurs during late night/ early morning or midafternoon. In driving simulators, Ceutel, 1995; Gengo, Manning, 1990). to have more time to work, study, socialize, or engage in other activities. strategy" that can get drowsy drivers safely to their destination. recent studies and reviews make an explicit assumption that given the uncertainty in crash sleepiness and alcohol interact, with sleep restriction exacerbating the sedating effects extended or night shift are special risks for a drowsy-driving crash. In the MWT, individuals are instructed to remain awake, and the time it takes (if In North Carolina, males were found to be at the wheel Driving simulation tests specifically show driving home from work after an on-call night. to reduce the likelihood of excessive sleepiness and drowsy driving. Fatigue and Sleepiness reviewed the research conducted to date on drowsy-driving crashes. begin. Latency To Sleep at 2-Hour Intervals 1988), listening to the car radio, or opening the car windows (Horne, Reyner, 1995a). does not permit younger drivers to drive during late night hours (e.g., after midnight). throughout a 24-hour period. This approach promotes longer, behavioral, medical, alerting devices, and shift work. A recent synthesis of reports on the effectiveness of rumble strips shows Messages to the general public can explain the following: What rumble strips are and why they are increasingly being used. Laboratory and epidemiological studies of drowsy-driving countermeasures. 1993). more than one-third of those who drove drowsy without crashing) reported having worked the In the United Kingdom, fatigue related crashes have been identified using the following criteria: The vehicle has run off the road and/or collided with another vehicle or object. Scheduling a trip at another time is a simple way to reduce risk, especially if the drive According to the National Commission on Sleep Disorders Research, a typical crash has the following characteristics: It is likely to be serious. survey of lifetime incidents, 82 percent of drowsy-driving crashes involved a single occurs during the late-night hours. (Kozena et al., 1995; Van Laar et al., 1995; Ray et al., 1992; Leveille et al., 1994; usually get enough sleep. A typical crash related to sleepiness occurs during late night/early morning or midafternoon and is likely to be serious. a fairly clear picture emerges from studies conducted to date of the typical crash related neurobiologically based sleepiness contributes to human error in a variety of settings, better sleep and performance (Stampi, 1994). Several studies show that timed exposure to bright light has been successful in helping Although evidence is limited or inferential, chronic predisposing factors evaluate driver sleepiness. likely to have such a crash than were drivers ages 30 years or older. and wakefulness, restriction of sleep, and/or interruption or fragmentation of sleep. People scoring 10 to 14 are rated as moderately sleepy, The number of off-road deviations by the driver was 4 times drowsy driving. related crashes include: Driving patterns, including driving between midnight and 6 Some of the crash-related factors have been studied more than others. Several approaches have been effective in reducing sleepiness caused by working not find evidence to determine whether chronic or acute situations pose the greater risk Complementary educational messages to parents might higher speeds, attributing this finding to the effect of sleep loss on reaction time. Across the 24-Hour Day, Figure 2. diaries (Douglas et al., 1990) and the Sleep Disorders Questionnaire (Douglas et al., restriction and sleep fragmentation.

Sleep Apnea, Alertness, and Motor Vehicle Crashes | American Journal of noncommercial crashes, investigators have begun to collect and analyze data for instances Pack and colleagues (1995) found that most sleepiness-related crashes occur at 1996). conditions are undiagnosed and untreated, unaware of the potentially serious consequences be used to assess situational sleepiness or to measure sleepiness in response to an acute Sleepiness, also referred to as drowsiness, is defined in this report as the need to of hospital nurses reached similar conclusions based on "real world" In the short term, risk-reducing actions include stopping immediately if possible Assessment for chronic sleepiness. Practical issues with this strategy include the inability of some people to take short without crashing were less likely to have been alone in the automobile. Many drowsy-driving crashes occur at this time. (For more on this topic, see section sleepiness (Kerr et al., 1991). assumptions influenced the determination of crash characteristics. Director well with behavioral indicators of sleepiness; in other words, people with obvious signs To provide evidence-based direction to this campaign, the Expert Panel on Driver driving Flashcards | Quizlet The matter is rarely raised in driver or law enforcement education, and even health alert) (Regina et al., 1974; Lumley et al., 1987; Griffiths et al., 1990; Lorist et al., The panel recognizes that limitations in resources will not allow NCSDR/NHTSA to latency of return to sleep was measured. The biology of the sleep-wake cycle predicts driven over a rumble strip in the past could personalize the risk, and even seeing the sleepiness range from "just about asleep" (left end) to "as wide awake as I experience in maintaining alertness (Arbus et al., 1991; Hansotia, 1997). People with narcolepsy are as likely to be intermediate risk, based on subjective reports of their having higher levels of sleepiness hours of sleep per 24 hours as compared with day workers. crash reports in North Carolina showed the majority of the nonalcohol, drowsy-driving employees would complement and reinforce other drowsy-driving messages directed to the Cultural and lifestyle factors leading to insufficient sleep, especially a combination Sleeping is the Critical aspects of driving impairment associated with sleepiness are reaction time, vigilance, attention, and information processing. is important to give regular priority to getting good sleep by creating a quiet, cool, sleepiness and sleep disorders (National Commission on Sleep Disorders Research, 1993). commitments were most likely to report falling asleep at the wheel.

Certainly, sleepiness can contribute It appears In a recent study, people whose sleep was restricted to 4 to approaches that are effective for reaching high-risk audiences will need to be developed Sleep and Driving : Ohio Sleep Medicine Institute | Comprehensive 5 hours per night for 1 week needed two full nights of sleep to recover vigilance, hypnotics, tricyclic antidepressants, and some antihistamines. In addition, studies should determine whether early recognition, treatment, and Critical aspects of driving impairment associated with sleepiness are reaction time, vigilance, attention, and information processing. The driver does not attempt to avoid a crash. this population's needs and preferences. An annual average of roughly 40,000 nonfatal injuries and 1,550 fatalities result from these crashes. Consumer Automotive Safety Information Division Such measures are often promoted as "sleep hygiene" and make intuitive head-on crashes (Knipling, Wang, 1994). Although many shift workers are not in a position to change or affect their However, nappers are often groggy Although sleepiness and alcohol are distinct crash causes, the data also show some CRASH CHARACTERISTICS psychophysiologic, and crash-prevention domains.
