Samenvatting
The California implied consent (IC) law requires that a motorist who has been arrested for driving under the influence of alcohol or a drug submit to a chemical test to determine the alcohol or drug content of the blood. A test refused results in the automatic loss of all driving privileges for a period of sixth months to three years.This study describes the IC system and answered a number of questions related to the program's operational efficiency and effectiveness, the characteristics of the target population, and its impact on traffic safety.
