The risks depend on how the driver is having to be manipulated to clear obstructions etc. If the driver is getting out on their own the problem does not really exist. If you are saying that they are having to be extricated
from the car, then how they are handled will be part of the rescue crew's factors to consider.
In general terms, the HANS will have to be removed before an extrication device such as a KED is applied. Removal is not teribly complicated. Cut the straps, remove the helmet and then remove the HANS by lifting up and backwards during that part of the extrication process which allows the KED to be positioned.
Of course if you are faced with integral extrication devices as in F1 or Formula BMW the order may differ.
Again of course, if the driver is not breathing, restoration of an airway and breathing support become the critical factors.
