The capability to see all around a vehicle is a fundamental requirement for any driver. If the driver can't see other vehicles or obstacles--either by direct vision or through the use of supplemental vision devices, such as mirrors--he or she is more likely to be involved in a crash.
The Technology & Maintenance Council (TMC) has developed a recommnended practice, entitled RP 428, "Guidelines for Vision Device," to specify minimum driver vision requirements and suggest various means of achieving these requirements. A task force within TMC's Cab & Controls Study Group is in the process of updating this RP and needs your help.
TMC is requesting all drivers to participate in a survey that will help the task force: Document the present vision needs of drivers, Prioritize the improvement actions needed, and; Provide an opportunity for fleets to provide valuable input on vision-related issues.
The survey involves gathering information on the use of both direct vision and indirect vision devices. Direct vision is defined as unaided vision as viewed through the vehicle windshield or side windows. Indirect vision is defined as vision aided by vision devices--usually mirrors.
The survey is designed to be completed in 5-10 minutes, unless you choose to give a longer written explanation or clarification (optional).
