At least 58,000 extra drivers have been caught speeding since police introduced a lower tolerance limit for long weekends and public holidays.
Since Queen's Birthday weekend in 2011, police have issued speeding fines to drivers caught travelling more than 4km/h over the speed limit during public holidays.
The usual tolerance is 10km/h over the limit.
The reduced tolerance accounted for nearly half of all speeding offences recorded for public holidays.
Police collected $5.7 million in fines for all speeding breaches during holidays and long weekends since 2011.
