The DieselTechWork Team covers pay, career paths, and hiring for diesel and heavy equipment mechanics. Pay and employment figures come from the U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics program. Living cost comparisons come from Bureau of Economic Analysis regional price data. Statistics about job listings, such as how often listings ask for a CDL, come from listings posted on DieselTechWork.
A fleet mechanic keeps one organization's own trucks, buses, or service vehicles running instead of fixing whatever customers bring in. You work for whoever owns the vehicles. That might be a trucking company, a city, a transit agency, or a food distributor. The typical diesel mechanic earns about $61,800 a year, and city and county fleets pay you well above that.
What Does a Fleet Mechanic Do?
You spend most of your week on scheduled maintenance instead of surprise breakdowns. About 3 in 4 fleet mechanic job listings mention preventive maintenance or DOT inspections. Your days follow a service calendar, and you get to know the same vehicles month after month.
A typical week includes these jobs:
- Preventive Maintenance - Oil, filters, brakes, tires, and fluid checks on a mileage or engine hour schedule.
- Inspections - Annual DOT inspections and the defect repairs drivers write up on their daily reports.
- Diagnostics - Reading fault codes on engines, exhaust aftertreatment, and electrical systems.
- Road Calls - Some fleets send you out to a broken down truck at a job site or on the roadside.
Some city and county fleet listings ask for experience on both light vehicles and heavy trucks. You may service a sheriff's SUV in the morning and a dump truck after lunch.
Who Hires Fleet Mechanics?
You will find the most fleet jobs at trucking companies, with city and county governments second. Trucking companies employ about 56,900 diesel mechanics, roughly twice as many as city and county governments, according to May 2025 federal wage data.
The rest of the fleet jobs sit with these employers:
- Transit and Bus Fleets - City buses, school buses, and charter coaches.
- Rental and Leasing Companies - Businesses such as Penske and Ryder that rent and lease trucks to other companies.
- Delivery Companies - Parcel and express delivery fleets.
- Private Company Fleets - Food distributors, concrete producers, utilities, and waste haulers that run their own trucks.
Search more than one job title when you look. Fleets post these jobs as fleet mechanic, fleet technician, shop technician, or equipment mechanic.
Fleet members of the Technology and Maintenance Council ranked technician shortages second among their maintenance concerns in spring 2025. "Technician recruitment, retention, and training are back on the list," wrote Fleet Maintenance (2025). You can use that shortage when you ask for a higher starting rate, and the diesel mechanic career outlook shows what to ask in the interview.
How Much Do Fleet Mechanics Make?
Your pay as a fleet mechanic depends more on who owns the trucks than on your job title. City and county fleets pay a typical $71,500 a year, compared with about $59,800 at trucking companies. At full time hours, a city or county fleet pays you about $5.60 more per hour than a trucking company.
City and county fleets employ about 28,900 diesel mechanics. That gives you the best mix of high pay and open jobs of any large employer type. If pay is your goal, apply to city and county fleets first.
Delivery companies pay the most at a typical $94,900 a year. Only about 4,500 diesel mechanics work there, and you should expect few openings near you.
Trucking fleets pay about the same as independent repair shops. If you weigh a trucking fleet against a shop, compare the shift, the overtime, and the tool allowance instead of the base rate. The fleet mechanic salary page shows the pay ranges employers post in current listings.
Is a Fleet Job Better Than a Shop Job?
A fleet job suits you if you like knowing your equipment and working a set maintenance schedule. A dealer or independent shop suits you if you want a wider mix of makes and problems.
| Fleet | Shop | |
|---|---|---|
| Vehicles | Employer owned | Customer owned |
| Work | Scheduled service | Walk in repairs |
| Pay Leader | Delivery companies | Truck dealers |
Nights and weekends come with many fleet jobs. About 1 in 3 fleet mechanic job listings mention night or weekend shifts. Ask which shift you start on before you accept.
Tools work differently at some fleets too. Several large private fleets pay you a yearly tool allowance. Ask about it in the interview, and count it with the hourly rate when you compare offers.

How Do You Get Hired as a Fleet Mechanic?
You get hired faster when your resume shows a CDL, ASE certifications, and preventive maintenance experience. Work through these steps in order.
Get Training or a Trainee Job - Most fleets want a diesel program or shop experience. The diesel technician trainee jobs page lists employers hiring beginners, and the how to become a diesel mechanic guide compares the ways in.
Plan on a CDL - About 4 in 10 fleet mechanic job listings mention a CDL. The CDL guide explains which license you need, and you can start early with DLA Academy's Class B training. Several city, county, and school bus fleets let you earn a Class B license within months of being hired.
Add ASE Truck or School Bus Tests - A similar share of fleet listings mention ASE certification. Truck fleets look for the medium and heavy truck tests, and school bus fleets use ASE's school bus series. The ASE diesel certification guide covers costs and test order.
Lead With Maintenance Work - Put the preventive maintenance services and DOT inspections you have done at the top of your resume, since those are the first duties most fleet listings name.

Frequently Asked Questions
Is a Fleet Mechanic the Same as a Diesel Mechanic?

Can You Become a Fleet Mechanic With No Experience?
You can, although most fleets want some training first. About 1 in 10 fleet mechanic job listings are open to entry level or trainee applicants. Search fleet technician jobs and look for trainee or apprentice in the title.
What Can a Fleet Mechanic Move Up To?
You can move up to shop lead, then fleet maintenance supervisor or manager. Supervisors of mechanics and repairers earn a typical $79,900 a year, according to May 2025 federal wage data.
