Assign the Primary Contact, DER, and Safety Officer
Last Updated: 09/24/2026
Med-Stop sends results, alerts, and administrative messages based on your company roles. Only one contact at a time can be the Primary Contact, the DER, or the Safety Officer. A DOT-regulated company must have a DER.
For a new contact
Use Company > New Contact. One step asks whether the person is the Primary Company Contact, DER, or Safety Officer.
For an existing contact
- Open Company > Contacts and select the contact.
- On the General page, select the roles the contact should hold in the role selection under the contact category.
- Select Update.
- Check the Function column in the Company Contact List to confirm who holds each role.
Tips
- Assigning a role to one contact replaces the previous holder. Change roles before a DER or Primary Contact leaves.
- The DER must be your company's employee. Service agents cannot act as your DER (49 CFR 40.3).
- After changing the DER or Primary Contact, review the contact numbers in Communication Setup.
