Transportation inspectors enforce safety rules that protect people and cargo. They inspect equipment and services and investigate accidents.

Inspectors examine and test a range of transportation vehicles, including cars, trucks, airplanes, trains, and boats.

Inspectors make sure vehicles operate properly and safely. They may use remote scanners or attach cables to check vehicle emissions. They compare this data with standards for the vehicle.

Inspectors look for parts that are broken. They also watch gauges and meters while engines and other equipment are running to monitor systems. They review logs to check that maintenance has occurred on schedule.

Some inspectors check to see that freight is loaded properly. They advise crews on how to brace freight securely. They may also use road side scanners to see if trucks need follow up inspections. They make sure that loads are not too big or heavy.

Transportation inspectors check security systems that limit public access to aircraft, ships, and trains. They may report unsafe practices to the police. They also evaluate paperwork to ensure documentation is complete and thorough.

Transportation inspectors prepare reports of their findings for owners and compliance officers. They issue certificates of compliance, and in some cases, issue citations. Inspectors recommend changes and make sure that vehicle owners follow their recommendations. Transportation inspectors study safety laws and rules.

Inspectors investigate accidents, delays, and complaints. They often testify in court and public hearings on safety issues.
