Advisory speed limit

Advisory speed limits are often set in areas with many pedestrians, such as in city centres and outside schools, and on difficult stretches of roads, such as on tight corners or through roadworks.

[citation needed] Advisory speeds in corners are set out in AS (Australian Standard) 1742.2-2009 Manual of Uniform Traffic Control Devices, Part 2, appendix F.[1] Corners are signed to indicate a speed at which lateral g-forces will not exceed 0.22g to fall well within the minimum suggested static rollover threshold of 0.35g for non-dangerous goods.

Exceeding the advised speed is not a criminal offense, but may result in greater liability in the case of a collision due to an increased danger of operating the vehicle.

[10] The signage for advisory speed limits is not defined by the Vienna Convention on Road Signs and Signals, and is therefore not standardised internationally.

[11] Australia uses a similar design as the United States in spite of regulatory speed limit signs being quite different.

Ireland and the United Kingdom currently use an oblong white rectangle, the latter with black lettering stating "Max Speed".
