In a survey of over 37,000 drivers carried out in June, 1.3% had a cell phone held up to their head and a further 2% were probably texting.

Survey

In June 2013 the Ministry commissioned a survey of hand-held cell phone use by drivers of cars and vans at 52 sites around New Zealand.

Handheld cell phone use by drivers was observed by surveyors standing on the roadside. Survey sites were spread across 7 urban centres and one rural town. Surveys were carried out during daylight hours on weekdays throughout June. Most surveys were situated where traffic had to slow, for example approaching an intersection. In some cases vehicles stopped in a queue were surveyed.

This was a pilot study designed to provide a snapshot of driver cell phone use. It was not designed to measure national rates across all times of the day and week.

Two categories of cell phone use were recorded; phone held to head and probably texting. ‘Probably texting’ was recorded when the driver was seen to be operating a hand held device in a manner that could be texting. Texting can be difficult to determine. A phone may be held out of sight or alternatively the device held may not be a phone (eg music player). No attempt was made to identify the use of hands-free cell phone use.

Note

This type of survey identifies how many drivers are using a cell phone at the time they pass the survey point. The percentage of drivers who ever use a hand-held cell phone while driving will be considerably higher than the results of this survey.
