Summary: Drunk Driving Repeat Offender Prevention Act of 2015  Directs the Department of Transportation to withhold specified graduated percentages of a state's apportionment of certain federal-aid highway funds for FY2018-FY2020 if the state has not enacted and is not enforcing a law requiring the installation of an ignition interlock device for a minimum of 180 days on each motor vehicle operated by an individual convicted of driving while intoxicated or driving under the influence. Defines &quot;driving while intoxicated&quot; and &quot;driving under the influence&quot; as driving or being in actual physical control of a motor vehicle while having a blood alcohol concentration of 0.08% or greater. Requires an ignition interlock device to:   require a driver to provide a breath sample before the motor vehicle starts, and   prevent a motor vehicle from starting if the alcohol concentration of the driver is above the legal limit.  Authorizes reduction of the 180-day period to 90 days if:    the driver's license is suspended for a minimum of 180 days as a result of the conviction, and   the period for installation of an ignition interlock device begins after the last day of the suspension.
