Questions from employers in this region
Nucor Steel runs continuous scrap inbound and rebar outbound CDL operations — how do you fit testing into their cycle?
Nucor's mini-mill model means CDL trucks are in and out around the clock. We stage collections at Nucor Dyersburg's scale house or designated testing area, testing scrap inbound and rebar outbound CDL drivers between loads — no one leaves the facility for a clinic.
Dyersburg is in rural NW Tennessee — is there a clinic alternative?
The nearest major clinic network to Dyersburg is a significant drive away, making on-site mobile testing the practical compliance solution for Dyer County employers. Our mobile collector comes to your facility — steel mill, textile plant, grain elevator, or carrier terminal — and conducts FMCSA-compliant collections on-site.
