The 30-year-old mother was stopped by police after zipping down the hill into Dunedin on Pine Hill Rd travelling at 68kmh - 18kmh over the signposted 50kmh speed limit - yesterday afternoon.
Asked to produce her driver's licence, and watched by two young women in her car's passenger seats, she instead handed over a learner's motorbike licence - her only driving qualification.
And, clutching infringement notices worth $520 moments later, she also revealed her excuse, telling the Otago Daily Times: "You can't help it if you are coming down [the hill] and you're on your brakes all the time.
"It's wear and tear on the brakes," she said.
It was not the only excuse heard over the weekend.
Dunedin teacher Michelle Golder (24) was clocked exceeding the speed limit on the same stretch of road, this time travelling at 65kmh in the 50kmh zone.
Approached by the ODT moments after receiving her $80 infringement notice, she conceded she "shouldn't have been speeding" but blamed her heavy foot on the need to pass her baby daughter a bottle.
"I was slowing down, but I was more concerned with the screaming child than the sneaky man with the camera," she said.
The two women were among 119 motorists issued with infringement notices by police targeting speeding drivers on roads into Dunedin over the weekend.
The team of three marked and two unmarked police cars swooped on five speeding motorists on Pine Hill Rd in just 15 minutes, while watched by the ODT staff members.
Police strategic traffic Acting Sergeant Andrew Camp said the two-day blitz was a prelude to January's "Operation Stop Speeding 2009", which begins today, targeting the city's speeding hotspots.
Some of the weekend's results were encouraging - like catching only 10 speeding motorists in two hours on the city's southern motorway on Saturday - but overall Sgt Camp said he was "very disappointed".
"I thought people would have started to learn by now, especially being the holiday season.
"All the messages about taking it easy and driving to the conditions and slowing down aren't getting through."
The worst offender was a Middlemarch motorcyclist caught travelling at 86kmh, also on Pine Hill Rd, yesterday afternoon, he said.
Sgt Camp was hoping more high-visibility enforcement this month would lead to an improvement in drivers' behaviour.
"But I wouldn't hold my breath," he said.
"Time will tell."
