If you’re weighing whether you need a commercial driver’s license to operate a wrecker or rollback, the answer turns on three knobs: the truck’s weight rating, what (and how) you’re towing, and whether you run intrastate or interstate. Get those right and the licensing picture becomes clear.
Bottom line preview: Most light-duty tow trucks (under 26,001 lb GVWR) can be driven without a CDL in many situations. The moment your ratings or your combination cross federal thresholds—or you haul placarded hazardous materials—you enter CDL requirements territory.
Introduction
Tow work looks simple from the curb—hook, lift, go—but towing operations live inside a web of federal regulations, state laws, and insurance terms. On any given shift you might rescue a delivery van from a loading dock, winch a box truck out of a ditch, then move a disabled tractor–trailer off a freeway shoulder. Each scenario changes the math on license class, endorsements, and compliance.
This guide explains when a CDL is required for tow trucks, how vehicle classifications and vehicle weight ratings drive the decision, and which checklists keep owners and drivers on the safe side of towing regulations.
Federal CDL Requirements for Tow Trucks
The Federal Motor Carrier Safety Administration (FMCSA) draws the line with vehicle weight limits and cargo type; states administer the licenses: https://www.fmcsa.dot.gov/cdl. Your starting point is the manufacturer’s label on the driver’s door: the GVWR (Gross Vehicle Weight Rating). If you’ll tow, you also care about GCWR (Gross Combination Weight Rating) and the GVWR of the towed unit.
Class A CDL
You’ll need Class A when you operate a combination where:
- GCWR ≥ 26,001 lb (11,794 kg) and
- the towed vehicle’s GVWR is > 10,000 lb.
Tow example: You’re in a medium-duty wrecker moving a disabled step van (12,500 lb GVWR). If your wrecker’s GCWR is 26,001 lb or more, that tow requires Class A. In practice, many heavy wreckers and integrated units live in Class A world the moment they pick up a large towed vehicle.
Class B CDL
You’ll need Class B when you operate a single vehicle with GVWR ≥ 26,001 lb and you’re not towing a unit over 10,000 lb GVWR.
Tow example: A 28,000 lb GVWR rollback transporting a passenger car. The truck alone crosses the heavy threshold—Class B applies—even if the car is light and strapped to the deck.
Class C CDL
You’ll need Class C if your operation doesn’t meet A or B but you:
- carry placarded hazardous materials, or
- carry 16+ passengers (not typical for tow, but possible for incident support or staff shuttles).
Tow example: Picking up a small service truck with a placarded hazmat load. If placards are in play, CDL with hazardous materials endorsement (H) is required, even if the tow vehicle itself is light.
Quick Table — CDL Classes for Common Tow Scenarios
| Tow scenario | Trigger | CDL class |
| 24,000 lb GVWR rollback carrying a sedan | Under 26,001 lb single vehicle | No CDL (check other rules below) |
| 28,000 lb GVWR straight-truck wrecker (no heavy trailer) | Single vehicle ≥ 26,001 lb | Class B |
| Medium wrecker moving a 12,500 lb GVWR box truck; combination ≥ 26,001 lb | Combo ≥ 26,001 and towed > 10,000 | Class A |
| Light wrecker towing a placarded hazmat pickup (any weights) | Placarded hazmat | Class C + H endorsement |
| Integrated heavy wrecker transporting a tractor–trailer from crash scene | Combo ≥ 26,001 and towed > 10,000 | Class A |
Tip: In towing, the towed vehicle’s GVWR typically counts toward the combination. That’s why “I only drive a medium wrecker” can still mean Class A when you pick up heavier units.
State-Specific Regulations
Variations Across States
While the federal motor carrier safety administration sets national baselines (license classes, drug/alcohol rules, qualification and inspection parts), state regulations and state-specific laws layer on practical realities:
- Intrastate vs interstate. Many states allow intrastate vs interstate splits—an 18–20-year-old driver may tow intrastate under rules the same driver can’t use for interstate trips.
- Tow truck licensing and business credentials. Several states require towing licenses or tow truck operator licensing (separate from your driver license). These can tie to rotation lists, fee postings, maximum rates, storage-lot standards, and accident reporting requirements.
- CDL exemptions for limited cases. Some states create narrow wrecker exemptions (e.g., short-distance recovery of a disabled vehicle) that do not waive everything—placards, weight thresholds, and insurance still bite.
- State licensing variations for endorsements. A few jurisdictions add local training or test elements specific to towing or “incident management” work.
Importance of Checking Local Laws
Two otherwise identical wreckers can have different obligations when they cross a state line. Before you expand service areas, verify:
- Minimum age and license class for your lanes.
- Whether your state recognizes commercial vehicle license alternatives (e.g., a non-CDL intrastate credential for certain weights).
- Rotation-list requirements for police tows, including response times, equipment, and insurance limits.
Additional Licensing Considerations
Tow Truck Endorsements
There isn’t a universal “towing endorsement” at the federal level, but three items matter everywhere:
- CDL endorsements:
- H (Hazmat) if you’ll ever move vehicles with hazardous materials that require placards.
- N (Tanker) is rare for tow ops but applies if you transport liquids/gases in bulk.
- T (Double/Triple) is for pulling doubles/triples—not typical for wreckers.
- H (Hazmat) if you’ll ever move vehicles with hazardous materials that require placards.
- Air brake endorsement / restriction removal:
- It’s technically a restriction removal. If you test in a vehicle without air brakes, you’ll carry an air-brake restriction and may be barred from operating air-equipped wreckers. Most medium and heavy tow trucks are air-brake platforms—plan your road/skills test accordingly.

- State add-ons:
- Some states or municipalities require an “incident management” card, rotation authorization, background check, or tow truck operator training certificate to work crash scenes or police tows—often bundled with tow truck safety regs.
- Some states or municipalities require an “incident management” card, rotation authorization, background check, or tow truck operator training certificate to work crash scenes or police tows—often bundled with tow truck safety regs.
Special Cases and Exemptions
- Emergency towing after a crash may unlock special emergency towing rules (e.g., temporary movement from lane to shoulder) but does not erase CDL thresholds if the combination qualifies.
- Hazardous materials limits still control. A disabled vehicle with placards remains a hazmat exposure during transport.
- Overweight allowances sometimes apply when recovering a disabled vehicle; you may still need permits afterward. Keep an eye on weight rating compliance and weight rating limits posted by the manufacturer.
- Medical certification for drivers: CDL drivers must maintain a valid DOT medical card; some intrastate programs permit waivers, but that’s case-by-case.
Compliance That Applies With or Without a CDL
A common misunderstanding: “No CDL means no big-rig rules.” Not so. Once your tow truck is a commercial motor vehicle in commerce (often >10,001 lb GVWR), you pick up significant obligations.
Compliance Matrix — What Typically Applies
| Topic | Light duty (10,001–26,000 lb GVWR) | Class B (≥26,001 lb straight) | Class A combos |
| Driver qualification standards (application, MVR checks, prior employment) | Yes | Yes | Yes |
| Medical certification for drivers (DOT med card; waivers where allowed) | Often required | Required | Required |
| Hours of service rules & logbook requirements (ELD or exception) | Often applies | Applies | Applies |
| Drug & alcohol testing (CDL holders in CMVs) | If driver holds CDL and operates CMV | Yes | Yes |
| Daily vehicle inspection & roadside inspection rules | Yes | Yes | Yes |
| Annual vehicle inspections (periodic) | Yes | Yes | Yes |
| Brake systems inspection (qualified inspector) | Yes | Yes | Yes |
| Vehicle inspection requirements (pre-/post-trip documentation) | Yes | Yes | Yes |
| Insurance requirements (financial responsibility) | Yes (varies by operation/for-hire) | Yes | Yes |
| Fleet maintenance rules (recordkeeping; defects corrected) | Yes | Yes | Yes |
Note: State adoption and intrastate carve-outs vary. When in doubt, assume the stricter rule.
How to Decide (Step-by-Step)
- Read the labels. Record the truck’s GVWR and GCWR plus the typical GVWR of towed vehicles you handle. This informs license class and weight rating compliance.
- Map to the thresholds.
- Single vehicle ≥ 26,001 lb → Class B.
- Combination ≥ 26,001 lb and towed unit > 10,000 lb → Class A.
- Hazmat placards in any weight → Class C + H.
- Single vehicle ≥ 26,001 lb → Class B.
- Clarify your lanes. Decide intrastate vs interstate. Crossing state lines can change age minimums, insurance, and HOS expectations.
- Check state overlays. Confirm state regulations, rotation rules, towing licenses, and business permits.
- Confirm endorsements. If you’ll touch placarded loads or air-brake wreckers, schedule the right testing to avoid restrictions.
- Build your files. Set up driver qualification standards files, logbook requirements training, and inspection recordkeeping before your first call.
- Train for the job you run. Align safety training standards to your mix (winching, rollovers, EV fires, roadside visibility, chain laws).
Equipment & Training — Practical Tables
Table 1 — Equipment Compliance Checklist (tow-ready essentials)
| System / item | Why it matters | Notes for tow fleets |
| Lighting & visibility (beacons, work lights, triangles) | Roadside scene safety; roadside inspection rules | Verify placement and function at each shift change. |

Edge Cases You’ll See on the Road
- Emergency towing from active crash scenes. Police rotations may require added credentials, response times, or specific equipment. These contracts rarely waive license classes; they simply authorize you to respond.
- Fueling restrictions. Company and local fire codes may prohibit fueling with engine running or while occupants remain in the cab; some facilities also restrict fueling with boom/bed extended. Build this into SOPs.
- EVs and hybrids. Treat battery-damaged vehicles as potential hazmat; follow OEM guidance, isolation distances, and coordinate with the fire department.
- Municipal recoveries. Some cities impose towing endorsements or local badges to work within city limits.
- Insurance audits. Carriers audit tow truck driver qualifications and MVRs; lapses in files or expired med cards can void coverage.
Training & Qualification: What Good Looks Like
- Tow truck operator licensing plus verifiable internal training on winching, uprighting, and incident management.
- A staged skills test (backing, positioning, rigging angles) and on-the-road road test in the exact equipment class you’ll operate.
- Recurring safety training standards: working the shoulder, reflective placement, night operations, securing EVs, and post-crash scene discipline.
- Clear SOPs for logbook requirements, hours of service rules, and proper use of exemptions (short-haul, adverse-driving, etc.).
- Documented fleet maintenance rules: mileage-based services, defect close-out, torque logs, hydraulic checks.
- Tight equipment compliance checklist at the start of every shift and after every recovery.
- A written chain-law plan to satisfy traction control requirements in winter corridors.
FAQs (Real-World Friction Points)
Q: My rollback is 25,999 lb GVWR. Do I need a CDL?
A: Not for the weight threshold alone. But you still face medical, inspection, HOS, and insurance obligations if you’re operating commercially—and you may need specific business licenses.
Q: We only tow intrastate. Does federal law still apply?
A: Much of it does, and many states adopt the federal parts for intrastate. Always check your state’s DOT/DMV site for tow-specific rules.
Q: Do I need special licensing for police rotations?
A: Often yes; departments publish rotation standards that double as tow truck licensing light—equipment lists, response times, rates, and insurance proofs.
Q: What about “CDL exemptions” for wreckers?
A: Limited, state-specific carve-outs exist for short-distance recovery, but they don’t override hazmat, weight, or combination thresholds.
Conclusion
A tow truck needs a CDL when the vehicle weight ratings or the combination (wrecker + towed unit) cross federal thresholds, or when placards bring hazmat into the mix. Light-duty operations may avoid a CDL, but you’ll still live under vehicle inspection requirements, hours of service rules, driver qualification standards, and insurance requirements. Because state laws add layers—from tow truck operator licensing to rotation-list contracts—build your compliance around the strictest rule you face and confirm the rest with your state agency.
If you’re building or upgrading a fleet, set your program on four rails: correct CDL classes and CDL endorsements, documented training, disciplined maintenance, and airtight paperwork. That’s how you stay ready for audits, pass roadside inspection rules without drama, and operate safely on the worst day someone else is having.
