I asked a mate who is highway patrol officer about the signage and his opinion was they couldn't book me for it but time will tell. I suppose it's a case of take it as it comes. There are a number of replica 05 and 25 race cars that sport the Marlboro signage that also have rego so we will wait and see. It's not something I'll be driving every day and I reckon the majority of the time it would be going to and from a rally where you could argue it has historical significance.
