In New Zealand, officers have the authority to request drivers to undergo an alcohol breath test. This is because drink driving is one of the leading causes of road traffic accidents, posing a serious threat to the safety of drivers, passengers, and other road users. The breath test allows for a quick assessment of whether a driver has consumed excessive alcohol, effectively preventing and reducing traffic accidents caused by drink driving, thereby ensuring the safety of public roads. Therefore, the power of officers to request breath tests is crucial for ensuring that all drivers comply with New Zealand's drink driving regulations and minimizing road safety risks.
