Palmerston North police were faced with a prickly problem during a drink-drive blitz on Milson Line on Friday night when a hedgehog tried to cross their checkpoint.
"His reason for crossing the road was not ascertained and he was not breath-tested," Senior Sergeant Brett Calkin said.
About 80 drivers were stopped and breath-tested at the checkpoint, with four found to be over the limit.
They included a 42-year-old woman who was almost three times the legal breath-alcohol limit, despite telling police she had had only two drinks.
