The Land Transport Act 1998 is a core operating law for New Zealand businesses that put vehicles on roads. At the general level, it requires drivers to be licensed, vehicles on roads to be safe and operated in compliance with the applicable rules, loads to be secured, and road users to comply with ordinary and emergency rules.
For some businesses, the Act goes much further. It includes transport service licensing, work time and logbook duties, offences for record failures, chain of responsibility offences, and some liability rules that can reach employers, principals, and directors in transport service offence cases. The key is to separate the general road-use duties from the more specialised parts.
