What is the primary purpose of a zero-tolerance law?

The primary purpose of a zero-tolerance law is to enforce strict penalties for underage drivers who have measurable alcohol in their system. This type of law is designed to deter young people from consuming any alcohol before driving, recognizing that even small amounts of alcohol can impair judgment and reaction times. By implementing strict penalties, zero-tolerance laws aim to create a safer driving environment for all road users, particularly because younger drivers may not have the experience to handle the effects of alcohol, even at lower blood alcohol concentrations.

The approach underscores the seriousness of underage drinking and driving, highlighting societal efforts to keep young people safe and minimize the risks associated with impaired driving. Hence, the primary objective is not about leniency or education per se, but about maintaining strict regulations to discourage underage drinking and driving completely.
