Yes they get into a panic very quickly here....4x4 quite able to cross BHP Rd with difficult parts near Cope Hut and the highest point out near Mt.Cope.Rd good for 4x4 drift surfing sometimes.....then sometimes Alpine Ash trees toppling over road as one goes lower...... Yet it's done for safety....we just except their judgement.....once they locked gate and I was stuck on FallsCk side after a day trip to Ropers Hut with gates closed....with big frontal system comming over night.A phone call to Cops and half an hour later they sent somebody to unlock gate!! The folk from Nth Hemisphere are somewhat more skilled to drive these roads...it's fun out there but obviously you don't want to get caught in a drift overnight.. I just accept their decision as to when they lock BHP Rd.In past years they did not padlock gates at first snow but closed them and wrapped chains around them....you knew that you accepted the risks in unlocking them and proceeding past!!
