Members of the public may have thought Wanganui was particularly bad for car accidents on the weekend.
But the dozen crushed and mangled cars popping up around town were nothing sinister - it was all part of an exercise for volunteer firefighters.
Senior station officer Jemal Weston said volunteer firefighters from around Wanganui and further away were taking part in an "accident extrication training course" over the weekend.
The roughly 14 volunteers spent some of their time learning theory before taking to the streets to respond to the fake car accidents.
Mr Weston said Molten Metals provided them with about 12 cars, which they were able to crush and place dummies and actors inside.
