Just after advise on WA DRIVING

I have to re-sit my driving test, and because of my licence conditions I need an alcohol interlock fitted. The problem is my only vehicle is a modified 80 Series LandCruiser, and I’m worried it won’t be the most suitable car for the driving assessor.

Has anyone here done their driving test without the interlock fitted and had no issues, or is it not worth the risk? Should I just do the test in my 80 Series with the interlock installed?

Or does anyone know if the accessors would know about my interlock condition
