What is the legal basis of speed signs in Victoria, Australia?
<p>When I went for my driver's licence test, they told me to follow the speed signs on the side of the road.</p>

<p>What law requires me to obey these signs, and what law authorises whoever puts the signs there to do so?</p>

<p>Road Rules in Australia in each state and territory are based on the <a href="http://www.ntc.gov.au/Media/Reports/(F1D63B25-98A0-8E5A-EBD4-BA6FC69ABF7D).pdf" rel="nofollow">Model Road Rules 2012</a>.</p>

<p>Each state and territory has enacted these rules (with some modifications; mainly relating to administrative matters) through their respective parliaments. The laws specifically for Victoria are the <a href="http://www.austlii.edu.au/au/legis/vic/consol_reg/rsrr2009208/" rel="nofollow">Road Safety Road Rules 2009</a> (Part 3 of which includes the obligation to obey speed limit signs) and the <a href="http://www.austlii.edu.au/au/legis/vic/consol_reg/rsmr2009373/" rel="nofollow">Road Safety (Traffic Management) Regulations 2009</a> (Part 2 of which says who can put up what speed signs where and prohibit ordinary people from doing so), both made under the <a href="http://www.austlii.edu.au/au/legis/vic/consol_act/rsa1986125/" rel="nofollow">Road Safety Act 1996</a> (section 95 and Schedule 2, items 44 and 45).</p>
