For drivers working through Redding.

Redding connects I-5 with SR 44 and SR 299. Whether your work involves long-haul freight, local delivery, construction hauling, or passenger transportation, confirm that your position is covered by DOT drug and alcohol rules.

A trucking job title alone does not establish coverage. Ask your employer’s designated employer representative (DER) which DOT agency and testing program apply.

Drivers based in Anderson, Shasta Lake, Cottonwood, Red Bluff, or farther along the SR 299 corridor can ask about appointment format before making a trip.

Bring the right information to your first conversation.

Know your test

Have the violation date and whether the test was DOT or non-DOT. If uncertain, ask your employer or testing program.

Know your employer contact

Have your DER’s contact information. Owner-operators should also identify their consortium/third-party administrator.

Know what you need to ask

Confirm fees, appointment format, documents, and the steps after the evaluation. Completion time depends on individual recommendations.

Common questions from Redding drivers

Can a negative test by itself get me back to work?

No. After a DOT violation, the required SAP process comes before the employer-arranged return-to-duty test. An ordinary test does not substitute for that process.

Can I complete the evaluation remotely?

Ask about the available format and whether it is appropriate for your situation. Confirm arrangements before traveling to Pine Street.

Does a SAP evaluation guarantee my job back?

No. The SAP evaluates compliance with recommendations. Your employer decides whether to return you to safety-sensitive work after applicable requirements are met.

Are treatment and testing included in the fee?

Request a written fee breakdown before booking, including initial and follow-up evaluations and any separate treatment, education, or testing costs.
