A warning circulating social media is a hoax - at least in New Zealand - and people are being urged to ignore it.
Rotorua Police posted on its facebook page asking users to ignore the message regarding "don't flash headlights at any car with no lights on".
"It has a CHUBB letterhead and claims to be a Police issued warning. This is a sham and has been circulating for a while however the police are still getting calls about it," the message read.
The warning is printed on Chubb letterhead with a South African address, and police are trying to trace its origins. The message has been shared across New Zealand, including in groups set up for small businesses, although the Rotorua police post has also been shared.
A police spokesman said it was "an urban myth that does the rounds every so often".
