We have had a number of enquiries regarding the mandatory requirement for use of HANS devices. These rules also apply to testing at MSV circuits – they enforce the MSA yearbook see below for details- therefore there will be a lot of exemptions and drivers can be reassured that there will be consistency between racing and testing.
Q10.1 (e) An FIA approved FHR device, fitted in accordance with K.10.4, is Mandatory for drivers in Circuit Racing. With the exception of Period Defined Vehicles for which it is recommended.
There is a definition for Period Defined vehicles in Section B of the Yearbook.
