Road rules and penalties

Take the road rules quizThere are many laws governing drivers, riders and pedestrians. If you breach the road rules or your licence conditions, you could incur demerit points, have to pay a fine or face more serious consequences like losing your licence.

Most driving offences are covered by the Road Traffic Act 1961 (RTA) and in Regulations made under this Act such as the Australian Road Rules (ARR) and the Road Traffic (Road Rules – Ancillary and Miscellaneous Provisions) Regulations 2014 (RT RR Regs).

In addition, the Motor Vehicles Act 1959 (MVA) regulates (amongst other things) the issuing of driver's licences, the registration of motor vehicles and compulsory third party insurance.

Hoon driving provisions are covered by the Criminal Law (Clamping, Impounding and Forfeiture of Vehicles) Act 2007 and the Criminal Law (Clamping, Impounding and Forfeiture of Vehicles) Regulations 2007, although the range of offences for which a car may be clamped or impounded are much broader.

Serious offences (otherwise known as indictable offences) such as causing death or injury by reckless or dangerous driving are contained in the Criminal Law Consolidation Act 1935.
