Trucks, planes, and ships

Licensed training to drive trucks, fly, fix aircraft, or crew ships.

  • CDL truck driving
  • Flight school
  • Aviation maintenance (A&P)
  • Merchant mariner credential

The short version

You need a license for this work, and there's a clear ladder of certifications.

It fits if you're drawn to hands-on, licensed work that moves people or goods.

Watch for: most routes need a medical exam, and training can cost a lot up front.

At a glance

Each scale shows its level and the reason, and "our read" marks a judgment call.

  • Cost while you do it

    Level: You pay quite a bit, 4 of 5 on the paying side

    Training can cost you a lot up front, especially flight training.

    Dollar signs to the left of the middle mean you're paid while you do it, and dollar signs to the right mean you pay. More of them means more money either way. The mark in the middle means free.

  • Time it takes

    Level: A year or less to about four years, 1 to 4 of 5

    A truck license takes months, while flight and aircraft training can take years.

  • Possible earnings once you're done

    Level: Above the middle to Higher, 4 to 5 of 5

    Truck drivers often earn above the middle, and pilots and aircraft mechanics earn more.

    This varies a lot with the specific job, the place, and experience.

    Middle means the middle pay across all jobs.

  • Getting in

    Level: A few requirements, 2 of 5

    Each route sets a minimum age, and most ask you to pass a medical exam.

  • Switching later Our read

    Level: Some of it carries over, 3 of 5

    A license goes with you, but training can cost a lot up front.

  • New experiences Our read

    Level: A lot new, 4 of 5

    These jobs often take you on the road, away from home, on odd schedules.

What it's really like

Long-haul drivers can be away for days or weeks at a time, much of it alone. Airline pilots may spend several nights a week away from home. Crews on barges or deep-sea ships may be gone for weeks or months. Aircraft mechanics work in hangars and repair stations, or out on airfields.

What it takes

A commercial driver's license (CDL) lets you drive within a state at 18 in most states, and across state lines at 21. For a first CDL, you generally must finish entry-level driver training with a registered provider. A private pilot certificate starts at 17 and a commercial one at 18. To get an FAA mechanic certificate you need to be 18 and have either an approved school or enough documented experience, but no FAA medical certificate. The FAA lists the current requirements. Most mariner work needs a Coast Guard credential and a TWIC (Transportation Worker Identification Credential) card.

Where it leads

A community college truck-driving program takes a few months, then you train on the job. Each program lists its current length. Pilots can build flying hours as instructors or charter pilots before applying to airlines. Aircraft mechanics can move up to lead mechanic, lead inspector, or shop supervisor. On ships, moving up takes several years of time at sea. Pilots typically earn the private certificate first, then commercial, then airline transport.

Pros and cons

Pros

  • The certifications form a clear ladder.
  • Pay often runs above the middle.
  • A truck-driving program takes a few months.

Cons

  • Training can cost a lot up front.
  • Most routes need a medical exam.
  • You may spend nights or weeks away from home.

If you change your mind

If you've ever held a Class A or B CDL, you skip entry-level training for that class. Under 21, a CDL only covers driving inside your own state. The FAA says a mechanic's skills carry over to many other industries. Some aviation maintenance programs at community colleges also let you earn an associate's degree.

Try it before you choose

  • Pick one route and read its licensing rules first.
  • Get the full price of the training before you start.
  • Find truck-driving training near you in the federal Training Provider Registry.

Questions to ask

Put these to a school, a program, or someone doing the work.

  1. What's the full price of the training, and what else will I pay for?
  2. Which license or credential does this lead to, and who issues it?
  3. How old do I have to be, and which medical exam do I need?
  4. In a normal month, how many nights will I be away from home?

People who did it

Barrington Irving first said no to becoming a pilot, because he didn't believe he was smart enough. He earned private and commercial pilot licenses, and at 23 he finished a solo flight around the world.
