The AA says controversial lower speed limits on rural Hastings roads place a "big cost" on the region but a senior policeman says a recent crash shows they can save lives.
Hastings District Council lowered speed limits on about 78km of roads in March but decided to review the changes after a public outcry.
Much of the criticism has been directed at speed reductions from 100km/h to 80km/h with motorist voicing frustration over increased travel times.
The council has received more than 1000 submissions on the changes and staff are currently analysing the feedback ahead of holding a hearing on the issue to be held on December 8 and 9.
In the Automobile Association's submission, the chairman of the organisation's Hawke's Bay District Council, Les Cunningham, said the time difference for a journey taken by a single vehicle at the lower limit may not seem large but "when this is multiplied over many thousands of vehicles, it becomes a big cost to the region that does not seem to have been factored into the council's decision to reduce speed limits".
