All drivers suspended for DUI in Kansas can apply for and receive a restricted Permit allowing for driving under limited conditions.  On a breath test failure, the waiting period is 45 days and the required length of the interlock depends on the breath test results; For instance,  a test of .15% or above requires the device for one year whereas a result under .15 requires a 6 month interlock unless the driver's record indicates prior suspensions for various convictions.  The waiting period for those who refuse is 90 days.  Regardless of the time period, an applicant should apply in advance of the eligible date to ensure the Permit is in hand when they qualify.  Too many suspended drivers fail to act in a timely manner and some will get stopped during the suspension and ultimately charged with Driving While Suspended.  This action could result in a probation or diversion revocation if the driver is on probation/diversion for DUI.  The best option is to obtain the Permit as soon as eligible and drive within the stated restrictions.
