MP for Wairarapa Alastair Scott said he was delighted to have his drug-driving bill pulled from the ballot last week in Parliament.
"Drug-driving is a significant road safety concern. In New Zealand, about one in three drivers in fatal and serious injury crashes have been found to have had some type of drug in their system," Scott said.
"The community wants to get drug-drivers off our roads. Nobody wants to share the road, or think of their loved ones sharing the road, with a driver on drugs.
"This bill will enable police officers to stop and perform a roadside drug test on any driver who they suspect is driving while under the influence of drugs.
Currently under the Land Transport Act, drug-driving is measured by an impairment test that involves an eye assessment and requesting a driver walk heel-to-toe in a straight line. This method has obvious limitations.
