An empirical study of the effect of different statistical rules. English summary of Brå report 1998:7

The National Council for Crime Prevention (Brå) was requested by the government to evaluate the 1994 legislative changes concerning various aspects of the offence of gross drunken driving. The evaluation was required to take account of the costs and consequences of the changes, to give special attention to whether traffic safety had been improved, to ascertain whether the courts' choice of sanction had been influenced by the changed legislation and whether the rate of relapse into drunken driving had changed.
