Plumber vs Truck Driver Salary
Plumbers earn approximately 11.5% more than Truck Drivers nationally — $61,000 vs $54,000.
Plumbers earn about $7,000 more per year, but reaching that point takes roughly 4 additional years of training.
What it takes to get in
Plumber roles typically require a high school diploma, while Truck Driver roles require a postsecondary certificate. From standing start to hireable, including training hours and licensing, the totals are roughly 5 years for Plumber and 1 for Truck Driver.
Those extra years are not free. Over a 40-year working life, becoming a Plumber consumes about 5 of them in training rather than earning, against 1 on the Truck Driver path. Holding pay flat at the median and ignoring raises, that leaves roughly $2,135,000 of lifetime gross for the Plumber versus $2,106,000 for the Truck Driver — still $29,000 ahead despite the later start. Real careers include raises and promotions, so read this as the shape of the trade-off rather than a forecast.
Licensing applies on both sides: State/local plumbing license required after apprenticeship for Plumber and Commercial Driver's License (CDL Class A) required for Truck Driver. Neither transfers automatically across state lines, which constrains where you can work on short notice.
Pay range, not just the median
The medians hide most of what matters. Plumber pay runs from roughly $39,000 at the low end to $105,000 at the high end; Truck Driver runs $38,640 to $78,800. Position within the range is driven by what you specialize in and who you work for, not by the title on the offer.
The two bands are shaped differently. Plumber top earners make about 2.7× what beginners make, against 2.0× for Truck Driver. A wide band means the ceiling rewards specializing and the median understates what is achievable; a narrow one means pay is more predictable and less dependent on landing the right niche.
What the work is actually like
Plumber: Residential and commercial job sites, crawlspaces, basements. Truck Driver: Long-haul cab, on the road for days at a time; regional/local routes vary.
The calendars are not alike either: Plumber runs on on-call rotations, Truck Driver on irregular hours that vary week to week. Worth weighing as heavily as the pay gap, because it is the part you live with daily.
Moving between the two
There is little skill overlap here — Trades and Transportation train differently and recruit through different channels — so a move between them is closer to starting over than pivoting. Pipefitters and steamfitters cross over directly; HVAC techs pick it up faster than average due to overlapping pipe and code knowledge. One of the fastest career switches available; many carriers offer paid CDL training in exchange for a work commitment, so entry cost can be near zero.
If you are entering rather than switching: Plumber — Complete a 4-5 year union (UA) or trade-school apprenticeship, then pass the state or local plumbing license exam. Truck Driver — Complete a 4-10 week CDL training program, pass the CDL skills/knowledge tests, then drive under a trainer for a company's onboarding period.
