Hawaii is slated to become the 47th state in the country to add an “ignition interlock” law to its books, according to a stateline.org article.
An ignition interlock device — sometimes referred to as a “blow and go” — requires its user to register their breath in a portable reader before they can start their car. Of the 47 states that have the laws — Washington’s is one of the strictest, stateline.org says — each vary as to how many DUI convictions one needs in order for the government to require them of a driver.
Stateline.org says some states, such as New Mexico, require them of first time DUI offenders. Here’s Washington’s law, courtesy of the state patrol.
