Most drivers who have reported recent use of a potentially problematic drug have said the drug has been prescribed for their use, providing ample opportunity for warnings from healthcare providers and drug labels. Reasons for further discovery and recall of warnings written in our study, as well as differences in drug categories, warrant further testing. All of these drugs should carry warning labels, but do not seem to be known and / or remembered by most drivers.
