Different Industries.
Different Compliance Triggers.

FMCSA Part 382 applies to drivers who operate commercial motor vehicles that require a CDL or CLP in commerce. That makes trucking and transportation the clearest fit for a federal DOT program, but coverage still depends on the driver and vehicle meeting the regulatory definitions.

Best fit for Skyside when you need ongoing FMCSA program administration across one or multiple locations.

Construction is not automatically a DOT-regulated industry. If a contractor employs drivers who operate CMVs requiring a CDL or CLP in commerce, those drivers may be subject to FMCSA testing rules. Equipment operators, tradespeople, and other employees are not made DOT-covered simply because their work is safety-sensitive.

A contractor can therefore need a DOT program for covered drivers and a separate non-DOT policy for other employees.

Forklift operators, machine operators, warehouse staff, and production employees are not DOT-regulated merely because their work can affect safety. A manufacturing or warehouse employer may still have FMCSA-covered drivers if it operates qualifying commercial motor vehicles and assigns CDL or CLP drivers to those vehicles.

The key is separating federally covered drivers from the rest of the workforce before building the testing program.

Dealerships, equipment rental businesses, tire companies, HVAC contractors, and field-service employers are generally not DOT-regulated as an industry. DOT rules may apply to particular employees if the business operates covered commercial motor vehicles and those employees perform covered driving functions.

For everyone else, testing authority should come from the employer's lawful non-DOT program, not a DOT form or DOT testing reason.

Staffing companies may place workers into CDL driving, warehouse, manufacturing, construction, or other roles. The correct testing program depends on the worker's assigned function and which entity has the employer responsibilities under the applicable rule and work arrangement.

This is a classification question first. Testing should follow only after the DOT or non-DOT authority has been identified.

USCG drug-testing rules apply to covered marine employers and personnel under 46 CFR Part 16. Not every port employee, marine contractor, dealership, or shoreside worker is automatically subject to Coast Guard testing simply because the business is connected to maritime activity.

USCG-required testing must remain distinct from company-policy or other non-DOT testing.

FAA drug and alcohol testing rules in 14 CFR Part 120 apply to certificate holders operating under Parts 121 and 135, air tour operators under section 91.147, and air traffic control facilities not operated by the FAA or the military. The drug testing rules also refer to programs conducted under Parts 65, 91, 121, and 135. Employees who perform the safety-sensitive functions in section 120.105 are covered, directly or by contract. Drug testing follows the DOT procedures in 49 CFR Part 40. Not every airport tenant, ground vendor, or aviation-adjacent employee is automatically covered.

FAA-required testing must remain distinct from FMCSA, USCG, and company-policy testing. Skyside helps aviation employers confirm which employees are covered and keeps that program separate from other testing. Read the FAA testing answer.

Colleges and universities can have a mixed workforce that includes facilities staff, campus transportation, maintenance, security, and administrative employees. Any federal DOT obligation depends on the specific covered transportation role, while other testing decisions belong under the institution's lawful non-DOT framework.

Skyside supports colleges and universities with pre-employment screening, employee testing programs, and training. Higher education is a specialized service, so contact Skyside to discuss your campus workforce and which program fits.
