While individual studies from several South American countries have shown  driving while intoxicated to be a problem, there are no objective systematically  collected alcohol-associated driving data obtained in most South American  countries. This limits their ability to implement and enforce targeted  prevention strategies, evaluate whether proven prevention efforts from North  America (particularly the United States and Canada) can be transferred to the  South, and to sustain momentum for the improvement of road safety by  demonstrating that previously implemented legal and policy changes are  effective.
The aim of this paper is to discuss the abysmal differences that  exist between northern and southern American countries regarding the current  status of driving while intoxicated prevention strategies—their implementation,  impacts and effects—using Brazil as a case example.
We propose a three-pronged  approach to close this northern–southern American gap in driving while  intoxicated prevention and intervention: (a) systematic collection on road  traffic crash/injury/death as well as risk factor data, (b) passage of laws  without loopholes requiring compliance with blood alcohol concentration testing  and (c) provision of appropriate training and equipment to the police in  concomitance with vigilant enforcement.
Resources and energies must be put towards data collection, implementation of prevention strategies and enforcement in order to decrease the unacceptably high rates of these preventable driving while intoxicated deaths.
