The Automobile Association has defended its hard line on driving tests as Wairarapa parents file formal complaints about young drivers failing their tests for what they claim are minor reasons.
Since an article appeared in the Wairarapa Times-Age outlining a mother's concerns of young learners being failed for minor flaws, more parents have come forward with their own experiences.
But Karen Dickson, the national manager of AA driver testing, said parents may not understand the need for harder tests.
She said the risks in driving had increased over the last decade.
"As a mum myself, I would have hated to get a white cross when my son was learning to drive," she said.
