Tested positive/refusal on a DOT alcohol/drug violation now you need to see a DOT SAP for initial and follow-up SAP assessment to get your CDL back. James Al Armstrong can help get that CDL back within days and get you back on the road. The follow-up assessment will include future random DOT testing that you will be required to take. 625 Strander Blvd. Suite C, Tukwila, WA 98188 is my location, but with a office space in Canada and multiple appointments I would love to accommodate to help get your CDL back. This includes surrounding areas like: Blaine, WA- Bellingham, WA- Lynden, Aldergrove, Sumas-Victoria and Vancouver BC.
