Statistically, we would be much better off, and probably have a far greater impact on both officer injuries and litigation, if we focused our training in two areas: defensive and evasive driving on the driving range, and a classroom session on EVO statutes and departmental policies. That way, we give officers the chance to practice the skills they need for avoiding a crash (some of which will obviously trickle down--or maybe, up--to pursuit situations), while reinforcing their understanding of their legal obligations and administrative responsibilities.
Any program that is likely to be successful in reducing traffic crash-related officer injuries, and the attendant litigation, must be multifaceted. It should include the training already mentioned, but should also include a careful policy review, as well as supervisory training. Along the same vein, departments should carefully examine the way their vehicles are equipped, realizing that a distracted driver is an accident waiting to happen--and everyone knows how distracting a modern, rolling "office" can be, especially when you're working alone.
Even if your department has very limited training resources (and who doesn't?), just conducting these reviews, and delivering the classroom training, can have a dramatic impact. And, the safer your officers are, the less likely they are to be injured, or to injure someone else. That means fewer lawsuits, and that's healthy for everyone.
