Louisiana ignition interlock device laws

Second and subsequent refusals: Your driving privileges will be suspended for two years if you refuse alcohol testing in addition to a prior refusal. You may be eligible for a hardship license in many cases if you agree to the installation of an Intoxalock ignition interlock or BAIID device for the period of suspension.

• A Refusal with a previous suspension on the driving record for Refusal, submit to the chemical test for intoxication, submit Underage, DWI, UDUI or Vehicular Negligent Injury. The Supreme Court ruled on October 16, 2012 that if there is a Refusal on a record with a prior alcohol related offense, installing the interlock as a condition of reinstatement is no longer required, unless the refusal resulted in a DWI conviction.
• A BAC of 0.08% or above received within five years of a previous suspension on the driving record for Refusal, submit to the chemical test for intoxication, submit Underage, DWI, UDUI or Vehicular Negligent Injury.
• A BAC of 0.08% or above or a Refusal involving an accident with serious bodily injury or, substantial risk of death.
• A BAC of 0.08% or above or Refusal where there was a passenger in the vehicle 12 years of age or younger.

• The ignition interlock device must be installed in all vehicles the driver will be operating prior to reinstatement of the driving privileges.
• As a condition of reinstatement, the ignition interlock device must remain installed for the duration of the suspension of driving privileges with a minimum requirement of 180 days. If a restricted interlock license was issued at any time during the suspension period, credit will be given for the time the interlock device was installed.

NOTE: The suspension or revocation time period associated with an alcohol-related offense, or refusal, may be longer than the requirement to have the ignition interlock device. If an offender chooses to remove the device prior to the end of their suspension or revocation period, their driving privileges will again be withdrawn until the suspension or revocation period ends and all re-licensing requirements are met.
