The relationship between blood alcohol concentration (BAC), age, and crash risk

Drinking and Parenting Practices as Predictors of Impaired Driving Behaviors Among U.S. Adolescents

“…Fosco et al (2012, pp. 210-211) hypothesized that the distinct outcomes for fathers and mothers in terms of teen problem behaviors may be attributable to "mothers' and fathers' parenting roles differ [ing] in terms of susceptibility to change in response to family stressors (Cummings et al, 2004) or family dynamics between mothers and fathers shap [ing] father involvement (Peck et al, 2008)." We speculate that fathers may be particularly credible referents regarding teenage drinking and driving.…”

“…For example, drivers younger than 21 with a positive blood alcohol concentration experienced twice the crash risk of those ages 25 and older (Peck et al, 2008). Novice teen drivers have especially high crash rates because of inexperience, contributing to the disproportionate effect on this population of driving while impaired by alcohol and/or other drugs (DWI; Peck et al, 2008;Voas et al, 2012).…”

The National Roadside Survey conducted for the National Highway Traffi c Safety Administration in 2007 found that, among drivers ages 16-20 tested at night, 16.1% tested positive for drugs other than alcohol (based on oral fl uids) and 7.2% tested positive for alcohol (based on breath alcohol measurements) (Lacey et al, 2009a(Lacey et al, , 2009b.…”

Effects of alcohol on automated and controlled driving performances

“…It is also important to note that our findings are based on a group of young but relatively experienced subjects (more than two years with a driving license) and cannot be generalized to other populations. Our next objective is thus to replicate the alcohol experiment with larger groups of very young, novice drivers who seem more often involved in road crashes with low alcohol level than experienced drivers (Zador et al 2000;Keall et al 2004;Peck et al 2008). As road crashes are generally due to a combination of several factors, it is possible that a lack of experience combined with alcohol, even at a low level, could have a cumulative effect on performances (Lenné et al 2010).…”

The Limits of Tolerance: Convicted Alcohol-Impaired Drivers Share Experiences Driving Under the Influence

“…Younger drivers with BACs in the 0.05% to 0.09% range have higher relative risks than older drivers because of immaturity, lack of tolerance to alcohol's effects, driver inexperience, and risk-taking propensity. 20 O's friends from the gathering were dumbfounded. "He was fine," his friend said, "He hugged my children, myself, and he was fine."…”
