This research brief describes work documented in The Effect of No-Fault Automobile Insurance on Driver Behavior and Automobile Accidents in the United States (MR-1384-ICJ).

Excerpt: A new RAND study refutes a common criticism of no-fault auto insurance — that it may increase the accident rate by reducing drivers' incentives to drive carefully. An analysis of accident trends in the United States between 1967 and 1989 found no statistically significant relationship between states' adoption of a no-fault system and the fatal accident rate, overall accident rates, and other measures of driver care.
