There is a developing belief that privately-administered, mandatory, truck driver training will create reductions in the frequency and consequences of truck collisions. These reductions must out weigh the generated costs that are monetary but will also include a reduction in the numbers of available truck drivers and a reduction in the numbers of smaller, independent trucking firms. This belief cannot be based on a naive belief that the data collected on truck collisions can be relied upon to accurately identify the true cause of truck crashes. These are some of the issues that need consideration.
