Nobody goes without a hump in Australia.

There is a proliferation of cheap, poor quality humps in Australia.
Quite often these humps don’t comply to standards, are of poor quality
from unknown origin, and are not suited to tough Australian conditions,
quickly fading or failing structurally.

Every reseller of humps in Australia will tell you their products comply
with the relevant standards. The reality is, many of them would not
even know the detail of the standards (or care), and in the vast majority
of cases their products do not comply at all.

The Australian Standards through AS2890.1:2004 have been very clear about
the design, use and intent of speed humps on private property.

Design criteria for speed humps:

The Australian Standard which regulates the design and use of speed humps
for use in off-street parking in Australia is ‘AS2890.1:2004 parking facilities’.

AS2890.1 identifies four main criteria in the design of “type 2” speed humps:
height, cross section, ramp angle and markings.

Until now very few “type 2” speed humps sold in Australia met these four criteria.
Of the non-metal type, most if not all are manufactured overseas from cheap,
very poor quality reclaimed materials of variable origin which quickly breakdown,
fade or fail under Australian conditions.

   Height: Must be between 25 & 75mm.

   Cross Section: Must be flat on top. Not round or peaked.

   Ramp Angle: Must have a ramp angle 2:1

   Markings: Must have alternating yellow or white stripes 250mm wide.
