Do forklift certifications expire under OSHA?

The employer certification under 29 CFR 1910.178(l)(6) has no federal expiration date. What runs on a clock is the evaluation: each operator's performance has to be evaluated "at least once every three years" under 1910.178(l)(4)(iii), and sooner, with refresher training, after any of the five triggers in (l)(4)(ii).

A new dock worker brings a card marked Certified Forklift Operator, with a March 2027 expiration date. The card does not authorize the worker to drive at this employer’s warehouse. The employer needs to evaluate the prior training, address the truck and site conditions, and establish that the operator can run the truck safely.

Does a forklift certification expire under OSHA?

A forklift certification records training and evaluation that have taken place. Paragraph 1910.178(l)(6) prescribes what the employer certifies, without setting an expiration date for that statement:

"The employer shall certify that each operator has been trained and evaluated as required by this paragraph (l). The certification shall include the name of the operator, the date of the training, the date of the evaluation, and the identity of the person(s) performing the training or evaluation."

The 1998 preamble to the final rule treats the certification as a record of the past: "OSHA believes that the certification required by the final rule is sufficient written evidence that the training and evaluation required by the standard has occurred" (63 FR 66261).

The three years come from another paragraph. Paragraph 1910.178(l)(4)(iii) says: "An evaluation of each powered industrial truck operator's performance shall be conducted at least once every three years." That deadline belongs to the evaluation. Once the last evaluation is more than three years old, the certification still records a real training and a real evaluation, and the operator is overdue for the next one. Calling the card expired can hide the duty that matters: evaluating the operator’s performance at least once every three years and providing refresher training when a listed trigger occurs.

What does a forklift certification have to include?

Four items, all in 1910.178(l)(6): the operator's name, the date of the training, the date of the evaluation, and the identity of the person or persons who did the training or evaluation. Paragraph (l)(6) asks for no signature, no card and no expiration date. Section 1910.178 never uses the words "signature," "card" or "license," and it sets no retention period for the certification.

OSHA has said who answers for the file. Its October 1, 1999 letter to the International Union of Operating Engineers reads: "Paragraph (l)(6) does not specify who must maintain the records; however, the employer is ultimately responsible for ensuring the availability of these records. Third-party trainers who agree to maintain the records would also need to ensure their immediate availability to the employer."

Two of the four items are dates, and they record two different events. Training under 1910.178(l)(2)(ii) is "a combination of formal instruction (e.g., lecture, discussion, interactive computer learning, video tape, written material), practical training (demonstrations performed by the trainer and practical exercises performed by the trainee), and evaluation of the operator's performance in the workplace." The evaluation date is the day a qualified person watched this operator work in your workplace. A certificate with one date on it, or a course completion date and nothing else, leaves an inspector guessing which event it records. Both dates belong on the certificate even when they fall on the same day, because (l)(6) asks for each.

The fourth item names a person, and the rule sets the bar for that person in 1910.178(l)(2)(iii): "All operator training and evaluation shall be conducted by persons who have the knowledge, training, and experience to train powered industrial truck operators and evaluate their competence." The same 1999 letter adds that "OSHA did not specify that the employer, or supervisor, or any other particular person, must conduct the training and evaluation, only that the training and evaluation be conducted by a person who is qualified." The training topics themselves, the long list in (l)(3), are laid out in our forklift certification requirements guide.

How often does a forklift operator have to be re-evaluated?

At least once every three years, under 1910.178(l)(4)(iii). "At least" makes three years the longest gap the rule allows, and nothing in it stops an employer from evaluating more often.

OSHA has been specific about what an evaluation is. The August 1, 2005 interpretation letter says:

The "evaluation" of "performance" required by the standard cannot be met by a written exam alone. A written exam by itself does not indicate whether the operator is operating the powered industrial truck safely.

In most cases, the same letter says, the evaluator would "first, observe the powered industrial truck operator during normal operations to determine if the operator is performing safely, and second, ask pertinent questions to ensure that the operator has the knowledge or experience needed to operate a truck safely." It calls the three-year check "the triennial evaluation."

Where the evaluation happens matters too. Asked whether it can rest entirely on observation of the operator in a training facility outside the workplace, the 2000 directive says: "No. The evaluation must take place in the workplace so that the evaluator can observe the operator under actual workplace conditions." That directive, CPL 02-01-028, is OSHA's compliance instruction for the operator training rule, and it includes inspection guidelines.

The 2000 directive also separates two kinds of evaluation. After refresher training, it says, the evaluation "does not have to be formalized but must consist of a person who has the knowledge, training, and experience observing each operator perform all typical operations to ensure that the powered industrial truck is being operated safely." It goes on: "OSHA requires that a more extensive evaluation be conducted at least once every three years."

None of this sets a passing score. The 1998 preamble says OSHA did not believe it possible, given the variety of trucks, workplaces, employee backgrounds and training, "to specify standardized tests or methods, or to specify passing grades." The evaluation criteria are discussed in Is there a passing score for an OSHA forklift evaluation?

When does the three-year count start?

The standard doesn't say. Paragraph (l)(4)(iii) asks for an evaluation "at least once every three years" and names no starting event, and nothing else in 1910.178(l) makes the training date or the evaluation date the anchor.

OSHA’s October 1, 1999 letter answered a question about the rule’s initial compliance date. The International Union of Operating Engineers asked whether employees trained before December 1, 1999, the compliance date, needed their performance evaluated "according to the 3-year anniversary of their training or the December 1 compliance date." OSHA's Directorate of Construction answered on October 1, 1999: "The date of the previous training controls the time frame for the next evaluation, not the compliance date for the standard." The choice in front of OSHA was a training date against a compliance date. The letter didn't weigh a training date against an evaluation held weeks later.

The 2000 directive calls for an evaluation "at least once every three years and as part of the initial training provided to the operator." That ties the first evaluation to the training, and it still doesn't say which of the two dates the next three years run from.

When the two dates differ, count from the earlier one. Take an operator trained on March 3 and evaluated on May 12. The 1999 wording puts the next evaluation by March 3 three years later, and a count from the evaluation puts it by May 12. An evaluation done by March 3 satisfies both. Counting from the evaluation date is a reading of (l)(4)(iii), which attaches the three years to the evaluation. Of the OSHA documents cited here, the only one that answers a start-date question names the training date.

Refresher training opens a second question the text leaves alone: whether an evaluation after refresher training starts a new three-year count. None of the documents cited here answers it. The 2000 directive treats them as two different evaluations: the one after refresher training "does not have to be formalized," while the three-year one is "more extensive." It doesn't say whether the first can stand in for the second. A program that restarts the count after a refresher, or declines to, is making its own rule and should say so in writing.

What forces refresher training before the three years are up?

Five events, listed in 1910.178(l)(4)(ii):

"Refresher training in relevant topics shall be provided to the operator when: (A) The operator has been observed to operate the vehicle in an unsafe manner; (B) The operator has been involved in an accident or near-miss incident; (C) The operator has received an evaluation that reveals that the operator is not operating the truck safely; (D) The operator is assigned to drive a different type of truck; or (E) A condition in the workplace changes in a manner that could affect safe operation of the truck."

Paragraph (l)(4)(i) pairs that refresher training with "an evaluation of the effectiveness of that training," so each trigger brings a refresher and an evaluation whenever it happens, whatever the three-year date says. The preamble explains the design: "First, the rule stipulates no fixed period for refresher training and evaluation; instead, such training is triggered when the triennial evaluation or an incident or workplace change indicates that it is necessary" (63 FR 66254).

Trigger (D) can come due without anything going wrong. An operator evaluated only on a sit-down counterbalance truck in the warehouse, then sent to run a rough-terrain forklift in the yard, has been assigned "to drive a different type of truck," and the evaluation on the first truck says nothing about the second.

An incident doesn't automatically take the operator off the truck. OSHA's October 1, 1999 letter says:

"The standard's performance language does not set an absolute requirement that an operator cease to work immediately following an incident. This allows employers flexibility when considering the severity of the incident that triggered the need for retraining."

The same letter adds: "The type, amount, and timing of refresher training depends on several factors, such as the equipment and terrain characteristics, nature of the unsafe act, and the potential for an accident or other incidents of unsafe acts or violations of §1910.178 to occur or reoccur." The call is the employer's. Write the reason down the day you make it, including what happened and whether the operator kept driving until the refresher.

Temporary operators fall under the same triggers. OSHA's February 16, 1999 letter to the International Warehouse Logistics Association says a temporary employee "involved in an instance of unsafe operation, an accident, or a near-miss incident, at a warehouse employer worksite would require refresher training as specified in paragraph (l)(4)(ii)." It also says: "A warehouse employer who supervises temporary employees would have the responsibility to ensure safe powered industrial truck operations."

Does a certification from another employer or a training company carry over?

Not on its own. Paragraph (l)(6) says "the employer shall certify," and (l)(1)(ii) reads: "Prior to permitting an employee to operate a powered industrial truck (except for training purposes), the employer shall ensure that each operator has successfully completed the training required by this paragraph (l), except as permitted by paragraph (l)(5)." Paragraph (l)(5) is where prior training comes in:

"If an operator has previously received training in a topic specified in paragraph (l)(3) of this section, and such training is appropriate to the truck and working conditions encountered, additional training in that topic is not required if the operator has been evaluated and found competent to operate the truck safely."

The last clause is the condition. Prior training can spare a new employer some topics, and the evaluation still has to happen. OSHA's February 16, 1999 letter puts the work on the hiring side: "Employers employing new operators or temporary labor operators who claim prior training would be required to evaluate the applicability and adequacy of prior training to determine if all required training topics have been covered." The factors it suggests are "the type of equipment the operator has operated; how much experience the operator has had on that equipment; how recently this experience was gained; and the type of environment in which the operator worked." On paperwork, it says: "The employer may, but is not required to, use written documentation of the earlier training to determine whether an operator has been properly trained." And on the site itself: "Some training on site regarding specific factors of the new operator's workplace is likely always to be necessary."

For the new dock worker, use the card to identify the prior training and truck type. Read it for the truck type and the date, then have a qualified evaluator watch the new hire run your truck in your aisles, and train them on whatever is particular to the site, like the dock plates and the pedestrian crossings. The certification you write afterward under 1910.178(l)(6) is yours.

A training company can do the training and the evaluation. The 1999 letter to the operating engineers says: "As long as the employer has a reasonable basis to believe that the third-party trainer is qualified and has a program that meets the requirements of the standard, it can rely on that trainer to conduct the training and evaluation of employees and can certify that these employees have been trained." It adds that "the employer may need to provide additional training on site-specific or truck-specific matters." Where an outside trainer did the training, the 2000 directive says "the employer must have evidence that the operators have been trained in the required program topics."

An online course fits inside the formal instruction of (l)(2)(ii), which names "interactive computer learning." The practical training and the evaluation still happen on a truck, and the 2000 directive puts the evaluation in the workplace.

Staffing agencies run on the same three years. OSHA's April 10, 2000 letter on employee leasing companies says: "Whether or not an assignment lasts longer than three years, the temporary employer must ensure that the operator's performance is evaluated at least once every three years."

Is the rule different on a construction site?

No. The construction section, 29 CFR 1926.602(d), says: "The requirements applicable to construction work under this paragraph are identical to those set forth at § 1910.178(l) of this chapter." The three-year evaluation, the five triggers and the four items on the certification apply word for word on a jobsite.

Construction weighed in during the rulemaking. The preamble records that the Advisory Committee on Construction Safety and Health (ACCSH) "commented that yearly retraining and evaluation are not as useful in the construction industry as other industries because relatively few employees remain with the same employer for an entire year" (63 FR 66254). OSHA answered that "by requiring formal evaluations of operators' proficiency only at three year intervals, OSHA is addressing ACCSH's concerns and the concerns of employers in other industries with high turnover rates." The next sentence matters on a crew that changes every season: "If an employee stays less than three years with the same employer, no periodic evaluation is required (although the evaluation associated with initial training and any refresher training would be required)."

An operator who works for four contractors in a year is a new hire four times. Each contractor owes the initial training and evaluation that (l)(7) sets for anyone hired after December 1, 1999, "Before the employee is assigned to operate a powered industrial truck," with (l)(5) sparing the topics the operator was already trained in, once the operator has been evaluated and found competent.

The 1999 letter came out of that world. OSHA's reply to the operating engineers repeats the union's point that many of its members "may work for several employers over the course of a year," and it places the training rule on construction employers: "under §1926.602(d), those requirements are applicable to employers engaged in construction." On coverage, the same letter says "neither a vertical mast nor a pivoted boom is a prerequisite for coverage under the standard." For the truck classes you'll run into on a jobsite, see our powered industrial truck classes cheat sheet for construction.

If your site is under a state plan, read that state's rule and guidance as well. The 2000 directive is labeled a "Federal Program Change for which State adoption is not required," and this article sticks to the federal text.

What happens when an inspector finds no certification?

OSHA's preliminary list of the Top 10 most frequently cited standards for fiscal year 2026, covering October 1, 2025, to August 31, 2026, ranks Powered Industrial Trucks, general industry (29 CFR 1910.178) seventh. The list counts citations from federal OSHA inspections under the whole section, which covers the fire protection, design, maintenance and use of the trucks, so it isn't a count of training violations alone.

Among its inspection guidelines, the 2000 directive says: "Determine whether the employer has certified that all required training and evaluations have been conducted." It also sets out what happens when only the paper is missing:

"When the employer has properly trained and evaluated powered industrial truck operators, but has failed to certify that the action was taken, no citation will be issued. The requirement for certification and the reasons for the requirement will be explained to the employer and the action noted in the case file. The employer will also be informed of possible penalties for subsequent violations."

That relief rests on its first clause: the training and the evaluation happened. An operator who was never evaluated, or whose last evaluation is more than three years old, is a different problem, and no certificate written afterward closes it.

Which forklift certification claims hold up against the text?

How do you keep track of every operator's next evaluation date?

A spreadsheet works if one person owns it and reads it on a fixed day each month. It needs the four (l)(6) items and the date the next evaluation is due. Add the truck type, since a move to a different type of truck brings refresher training under (l)(4)(ii)(D) whatever that date says. For one certification on paper, the free Forklift Operator Certification Record asks for the operator name, the date of training, the date of evaluation and who trained or evaluated, then downloads the record as a PDF.

HazComFast answers the question a dock supervisor gets before noon: who can drive today. "Forklift Operator Evaluations" counts each operator once, from their latest evaluation, as Current, Due soon, Overdue, No next evaluation date or Not authorized to operate, and a banner at the top calls out the cases that need someone to act. An operator whose latest evaluation wasn't passed shows as not authorized, with the refresher training of 1910.178(l)(4)(ii)(C) cited beside the reason.

The three-year date can't get lost. As soon as the evaluator attests, "Next Evaluation Due" fills in three years after the evaluation date, with (l)(4)(iii) quoted under it, and a passed evaluation won't save without it. Thirty days out, the manager and the operator are notified and a corrective action for the re-evaluation opens, due on that date. Counting from the evaluation date is HazComFast's reading of (l)(4)(iii), and a site that counts from the training can move the date earlier.

The certification holds up when someone asks for it. Each evaluation names its evaluator, with the qualification declared under 1910.178(l)(2)(iii), and the evaluator attests the result. Any later edit asks for that attestation again. "Download PDF" produces the certificate with its "OSHA 29 CFR 1910.178(l)(6) Certification" block, which lists the operator's name, the training date, the evaluation date and the evaluator, followed by the result of each criterion and any outside certificate attached to the record. On a construction jobsite, the certificate adds "29 CFR 1910.178(l) applicable to construction via 29 CFR 1926.602(d)."

A passed evaluation also lands in the worker's training file and on the truck's own record, and it goes into a defense package as a training record. Operators open their own certification on "My forklift certification," on a phone or a computer, with the PDF one tap away.
