Are there laws in the ACT that prevent a P-plater driving anything more than a 6 cylinder vehicle? Last Saturday night I was passed on Hindmarsh Drive by a silver Holden Commodore SS (ACT registration YGY-06P) travelling at what I estimated to be around 170-180km/h in an 80km/h zone. There were 4 youths in the car and it was displaying red P-plates.#30
