The Land Transport Amendment Act (no 2) 2014 to lower the drink-driving limits for adult drivers aged 20 years and over passed into law on 8 August 2014.
The lower limits came into force on 1 December 2014.
The Act lowered the breath alcohol limit for adult drivers from 400 micrograms (mcg) of alcohol per litre of breath, to 250mcg. The blood alcohol limit has reduced from 80mg of alcohol per 100ml of blood, to 50mg.
Drivers who commit an offence between 251-400mcg of breath face an infringement fee of $200 and receive 50 demerit points. Drivers who accumulate 100 or more demerit points from driving offences within two years receive a three month driver licence suspension.
The zero alcohol limit for drivers under the age of 20 years remains the same.
The Transport and Industrial Relations Committee reported (external link) back to the House on 19 June 2014. The Committee considered 106 written and 21 oral public submissions on the Bill.
