Masterton's Fleur Hardman is the winner of the Wairarapa Road Safety Council's quiz, earning $1000 in prizes.
The quiz was run over International Road Safety Week, from May 4-8.
The prize includes a $250 automotive workshop voucher - a blessing for Ms Hardman, who said her car needed repairs.
She said she was "thrilled".
Road safety council manager Bruce Pauling said the quiz, published in the Times-Age and another paper, was about engaging people with road safety topics, and directing participants to road safety sites such as the NZ Road Code and www.rightcar.
"Teaming up with local businesses enabled the substantial prize."
Autofix, Mobil garages, Supercheap Auto, Motordrome and Getwaxed car groomers sponsored the prize.
