What transportation inspectors do
Transportation inspectors keep people safe on highways, rails, waterways and in the air. Depending on the agency or employer, they might inspect commercial trucks and buses at roadside, audit motor carriers, inspect aircraft maintenance and pilot operations, check railroad track and equipment, or verify that freight and hazardous materials are loaded and labeled correctly.
Most inspectors are hired after years of experience as mechanics, drivers, pilots, railroad workers or law enforcement officers, then trained by their agency. The FAA, FMCSA, FRA, state DOTs and state police employ many inspectors, as do railroads and freight companies.
