News from NZ Police
The Paekakariki Hill Road was closed to traffic in both directions this afternoon when an articulated truck known as a B Train became wedged on a bend in the road after following GPS instructions that led the driver to Paekakariki Hill Road, which is unsuitable for a vehicle of that size.
It was an hour or more before the road was reopened to traffic again.
Later in the day, Constable Scott Walker of Kapiti told the DomPost that the driver was arrested during the incident for driving while disqualified . He said the truck became jammed under a tree about 500m below the summit.
Wikipedia: A B-Train (as related to the road transport or trucking industry) consists of two trailers linked together by a fifth wheel, and can be up to 26 m (85ft) long.
