While the State is allowed to criminally prosecute people arrested for DWI who blow under the .08 limit, the ALR statutes provide that a person’s driver’s license may not be suspended in that situation, if the defendant is 21 or older.
Texas Transportation Code Section 524.012 (c) (1) specifically states:
(c) The department may not suspend a person's driver's license if:
(1) the person is an adult and the analysis of the person's breath or blood specimen determined that the person had an alcohol concentration of a level below that specified by Section 49.01(2)(B), Penal Code, at the time the specimen was taken.
However, for those under 21 who provide a breath specimen above .00 and below .08, the Department of Public Safety will seek the shorter 60 day suspension period for DUIM, driving under the influence by a minor.
