Delaware Ignition Interlock Laws

For first-time offenders and repeat DUI offenders, your license will be confiscated immediately per Delaware’s Administrative License Revocation (ALR) if:

Your blood alcohol concentration (BAC) level was .08 or higher
You refused a breath test

If the offender’s BAC is .15 or higher, courts in Delaware require an Ignition Interlock Device (IID) to be installed and maintained on the offender’s vehicle. You’re required to pay for all costs associated with the IID, from installation, monthly lease payments, and service fees to removal. You may have to attend an alcohol education program.
