SODAT-Delaware, Inc. is authorized by the Office of Highway Safety to operate the DUI Evaluation and Referral Program (DERP). Every individual who is arrested in the State of Delaware for a DUI violation, or is otherwise under Delaware’s jurisdiction for a DUI offense, is evaluated by SODAT and then referred to an educational or treatment agency, as appropriate.

DERP’s administrative offices are located in New Castle County, but evaluations are done in all three counties in the state of Delaware. Your DUI evaluation will be scheduled at the office most convenient to you.

The DUI evaluation takes approximately 90 minutes and involves an interview with a trained evaluator. Within five (5) to 10 business days following the completion of your DUI evaluation, you will receive a letter with your referral and all of the information you will need to schedule your classes.

The fees for this service are as follows:

$35 (for failure to cancel within 24 hours)
$35 (for changing from one DUI provider to another, once initially referred)

We accept cash, money orders, and certified checks, as well as Visa, MasterCard, Discover. Credit cards must be in the name of the person being evaluated. We do not accept personal checks.

To schedule your appointment, please contact the New Castle County office at (302) 656-2810 or (800) 551-6464 (for in-state long distance calls only). Our offices schedule from 8:00 am to 7:30 pm Monday through Thursday and from 8:00 am to 4:00 pm on Friday.
