 In Victoria and Western Australia they meant that the rural default speed limit applied, whilst in New South Wales, they indicated that the "prima facie" limit applied.New South Wales's "prima facie" limit, often signed by derestriction signs, was only enforced in cases where a driver's speed could be demonstrated to be excessive or dangerous in the context of prevailing road conditions.This was somewhat similar in principle to "reasonable and prudent" limits in other jurisdictions.
