Driving while abilities impaired. This acronym is used in Colorado to refer to a lesser charge that is related to drunk driving, but does not carry all of the same consequences and punishments. A DWAI conviction, in those few states that offer DWAI, may not be considered a prior conviction for drunk driving purposes in other states. It is important to consult a drunk driving lawyer that is well-versed in this area of the law to ensure your rights are protected.
