One in 10 people who have taken a popular online test on our new give-way rules answered at least one question wrong - worrying the man who helped design it.
More than 120,000 people have visited the website GiveWay.co.nz and sat a simulation placing them behind the wheel of a Suzuki Grand Vitara in 14 real-life give-way scenarios around suburban Hamilton.
Waikato University road safety researcher Dr Robert Isler, who conceived the test with daughter Nadine Isler, said an analysis of 650 results from last week also found that people took on average five seconds to answer correctly - and 10 seconds to give the wrong answer.
Most of those who stumbled did so at the first scenario - whether to give-way to a left-turning car when turning right from a median.
Many also failed to give way to a cyclist approaching from behind on a cycle lane.
