A farm fence was the only thing that stopped a car - carrying a toddler and two adults - from rolling down a bank in the Paraparas last month.
Levi Alexanda Taitumu-Chase was driving in breach of his learner licence, and in an unregistered and unwarranted car, on June 4.
He had another man, and a 2-year-old child in the car with him as he drove along the Parapara Rd.
Taitumu-Chase was trying to overtake a truck and trailer unit when he saw an oncoming vehicle and pulled back into the lane, police prosecutor Sergeant Rachel Willemsen said in the Whanganui District Court on Tuesday.
Taitumu-Chase had to brake hard, causing the car wheels to locked up and the car to skid for nearly 90m.
The car spun, and ended up against a farm fence that stopped it from going down the bank.
He pleaded guilty in court to careless driving.
Judge David Cameron fined him $250 and $130 court costs.
