Speed limit changes will be rolled out across many Waikato state highways this month as roading bosses look to turn around the region's lacklustre safety record.
NZ Transport Agency state highway manager Kaye Clark said the 11 speed limit changes were aimed solely at improving safety.
"We're aiming to reduce deaths and serious injuries by taking action in four key areas - safe roads and roadsides, safe vehicles, safe road use and safe speeds," Mrs Clark said.
"In addition to investing in safer roads and roadsides and promoting safer driving and safer vehicles, lowering travel speeds on some of our high-risk sections of road will help to reduce crashes and reduce the severity of those crashes that do occur."
Mrs Clark said even small reductions in speeds could greatly reduce the risk of crashes happening and increase the chances of people surviving those crashes.
This year the region's road toll sits at 40 - the country's highest.
Last week, NZTA published data showing Waikato's roads remained the most dangerous in the country.
State Highway 1 from Huntly to Hamilton is the country's "riskiest" stretch of highway - with 30 serious injury crashes and 11 fatal crashes in five years.
Mrs Clark said the transport agency wanted a reduction in unsafe speeds, including speeding and travelling too fast for the conditions.
"If we achieve this, we will see a reduction in all crashes, not just speed-related ones. The NZTA is improving basic features such as road markings and signage to help road users identify and understand the speed limit.
"If a road is difficult to read or if it carries a high level of community activity, and is used by pedestrians and cyclists, then its speed limit should reflect these conditions."
NZTA consulted police, AA, Road Transport Association, councils and communities in deciding the new speed limits.
