A Dunedin driver who "fell asleep" before crashing is suspected of huffing nitrous oxide while behind the wheel. Police arrived and he told officers that he "fell asleep" while driving. He underwent breath testing procedures and a compulsory impairment test, and passed both. Police found a "large" collection of nitrous oxide canisters — also referred to as "nangs" — sitting in the boot. Nang usage would not show up in a compulsory impairment test.
