Can you drive a forklift on the road? In most states, yes, but only for short, work-related trips and only if the machine is equipped for traffic, the operator holds the right license, and the forklift is properly registered and insured. Anything beyond a brief incidental crossing usually falls outside what the law allows.
When State Law Allows It
The federal government does not treat forklifts as highway vehicles. The National Highway Traffic Safety Administration has said that mobile construction equipment whose highway use is “merely incidental” to its primary off-road purpose falls outside the federal motor vehicle definition.1NHTSA. Interpretation ID 86-4.4 That pushes the rules down to the states.
Most states classify forklifts as “special mobile equipment” or something equivalent. The common thread is that road use has to be brief and directly tied to the machine’s work purpose. Typical permitted trips include crossing a public road to reach another section of the same property, moving between adjacent job sites, and certain agricultural operations. You generally cannot use a forklift to run errands, commute, or travel any distance where a trailer and truck would be the obvious alternative. Some states effectively prohibit road use altogether, so the first step is always to check how your state classifies the machine.
Equipment the Forklift Needs
A bare warehouse forklift is not road-ready. States that permit limited road travel require the machine to be visible and controllable in traffic. Expect to need headlights, taillights, brake lights, turn signals, mirrors, and a working horn. OSHA already requires headlights in low-light areas and horns where vision is obstructed, so some machines will have a few of these already.2Occupational Safety and Health Administration.

A slow-moving vehicle emblem is required in every state for machines that travel at 25 mph or less on public roads. It is a fluorescent red-orange triangle with a reflective red border, mounted on the rear where approaching drivers can see it from a distance. Since most forklifts top out well below 25 mph, the emblem is effectively mandatory whenever one enters a public road.
Tires matter too. The hard rubber or polyurethane cushion tires on most indoor forklifts are made for smooth warehouse floors. They offer almost no traction on wet pavement and can damage road surfaces. Pneumatic tires, either air-filled or solid pneumatic, are better suited for outdoor use, and some jurisdictions explicitly require road-appropriate tires before allowing a forklift onto public pavement.
Width is the last thing to check. Forklifts with wide masts or attachments can exceed standard lane widths. Most states require oversize load permits, warning flags, or escort vehicles for any equipment wider than 8.5 feet. If your machine is wider than a standard traffic lane, call your state transportation department before moving it.
Who Can Legally Drive It
Two separate credentials apply on a public road, and one does not substitute for the other.
OSHA Operator Training
Every forklift operator must complete employer-provided training that includes classroom instruction, hands-on practice, and a workplace performance evaluation before operating any powered industrial truck. The training covers load handling, vehicle stability, steering, visibility limitations, and hazards specific to the work environment.3Occupational Safety and Health Administration. Powered Industrial Trucks (Forklift) – Training Assistance Refresher training is required whenever an operator is observed driving unsafely, is involved in an accident or near-miss, or is assigned a different type of forklift. This is a workplace safety requirement. It does not authorize you to operate any vehicle on a public road.
Driver’s License and CDL
Operating any motor vehicle on a public road requires a valid state driver’s license, and a forklift is no exception. The more important question is whether a commercial driver’s license is required. Under federal rules, a CDL is required to operate a single vehicle with a gross vehicle weight rating of 26,001 pounds or more.4FMCSA.

Most warehouse and standard-capacity forklifts weigh between 5,000 and 15,000 pounds, well under the CDL threshold. Heavy-duty outdoor forklifts with high lift capacities can weigh 20,000 pounds or more. If the GVWR approaches or exceeds 26,001 pounds, a CDL is necessary. Check the data plate on the machine if you are unsure.
Registration and Insurance
Whether you need to register a forklift with your state’s motor vehicle agency depends on how the state classifies it. Many states exempt “special mobile equipment” from full registration when road use is limited and incidental. Some states issue a special permit instead. Others require full registration the moment the machine touches a public road, no matter how briefly. There is no single national rule, so a call to your state DMV before driving a forklift off your property is the only safe approach.
Insurance is where many businesses get caught off guard. Standard commercial general liability policies define “mobile equipment” and “autos” differently, and the distinction often turns on whether the vehicle is subject to a motor vehicle insurance law in the state where it operates. A forklift sitting in your warehouse is typically covered as mobile equipment under your general liability policy. The moment you drive it onto a public road where financial responsibility laws apply, it may be reclassified as an “auto” for insurance purposes. If your commercial auto policy does not list the forklift, you could have a gap in coverage right when you need it most.
The practical fix is to talk to your insurer before any forklift leaves your property on a public road. Some businesses add the forklift to their commercial auto policy. Others obtain a specific endorsement. The worst outcome is assuming your existing coverage handles it and finding out after an accident that it does not.
What Happens If You Get It Wrong
A forklift collision on a public road creates legal exposure that goes well beyond a typical fender-bender. Both the operator and the employer can face consequences.
If the forklift lacks proper registration, required safety equipment, or the operator does not hold the right license, the operator can be cited for traffic violations. In many states, driving an unregistered or improperly equipped vehicle on public roads is a misdemeanor. Fines vary by jurisdiction and can increase when the violation contributed to an accident.
The employer’s exposure is broader. Putting a forklift on a public road with an untrained or unlicensed operator opens the door to negligent hiring and supervision claims. An injured person would need to show the operator was unfit for the task and that the employer knew or should have known. A missing OSHA training record or an expired license makes that case much easier to prove. Employers are also generally liable under standard vicarious liability principles for their employees’ on-the-job actions.
Insurance gaps compound everything. If the forklift is treated as mobile equipment under your general liability policy but was actually functioning as a road vehicle at the time of the accident, the insurer may deny the claim. That leaves the business directly responsible for medical bills, property damage, and any personal injury judgment.
Before You Drive It Onto the Road
Most forklift road trips happen because someone decides it is faster to drive across the street than to load the machine onto a trailer. That shortcut can work, but only with the legwork done in advance:
- Look up how your state classifies forklifts and what it requires for road use. Some states have straightforward special-equipment provisions; others effectively prohibit road use.
- Inspect the machine for every piece of required road equipment: lights, signals, mirrors, horn, SMV emblem, and road-suitable tires.
- Verify the operator has current OSHA training for that specific forklift type and a valid driver’s license, plus a CDL if the GVWR requires one.5FMCSA. What Is the Difference Between a Commercial Motor Vehicle (CMV) and Non-CMV
- Contact your DMV about whether you need a permit, a registration, or whether your state’s special-equipment exemption applies.
- Confirm with your insurer that the forklift is covered for road use, and get it in writing.
- Keep the route short. Avoid busy intersections, hills, and high-speed roads. Use a spotter or escort vehicle if the forklift is wide or unusually slow.
When the alternative is a five-minute trailer ride, the math almost always favors the trailer. The situations where driving a forklift on a road genuinely makes sense are rare, brief, and involve a property line that happens to have pavement running through it.
