The 10km/h speed enforcement threshold has been reduced to 4km/h during official holiday periods in New Zealand since Queen’s Birthday weekend 2010. The 2013/14 Safer Summer road safety campaign was the first time the speed enforcement threshold reduction had been extended beyond official holiday periods to a full two month period.
The campaign was carried out by Police from 1 December 2013 to 31 January 2014, and supported by the wider road safety sector. It involved a well-publicised reduced speed enforcement threshold, combined with intensified and highly visible speed enforcement.
The final report evaluates the effects of the campaign on speeding and crashes.
