The impaired driver. A critical review of the facts.

Traffic accidents have been subject to relatively little scientific study in California. A substantial barrier to adequate basic research in this field has been the assumption that more is known about the underlying causes of accidents than actually is. For example, within the medical profession, there is a tendency to assume that physical impairments of drivers are important in the causation of accidents, although little evidence has been collected to confirm or deny this assumption.Research into the underlying causes of accidents is a worthy but infinitely complex task. It must be accomplished before the driver's contribution to accidents can be seen in proper perspective, its components identified and dealt with on a rational basis.
