Sections 1(8) and 1(9) FSG-GV divide motor vehicles into two groups. Group 1 includes categories AM, A, A1, A2, B, BE and F. Group 2 includes categories C, C1, CE, C1E, D, D1, DE and D1E. The distinction matters because section 9 FSG-GV sets different hearing distances for the two groups.
The group follows the requested or existing driving categories, not the job title alone. Someone who wants to drive a passenger car is therefore not assessed by exactly the same standard as someone holding an entitlement for heavy vehicles or buses.
The guidance on medical fitness for professional drivers addresses the specific group 2 context. This article stays focused on hearing and balance.
