Forklift operator screening questions should establish which class of truck the candidate has actually driven at work, doing which task (trailers, racking at height, order picking, yard work), how recently, and at what pace. Then ask what the client's site evaluation will involve and whether the candidate is ready for it. A card proves someone attended training once; the truck, the task, the date and the rate tell you whether they will pass the client's evaluation on day one.
This page goes deeper than the forklift section of light industrial screening questions, which is built for seven-minute volume calls across pickers, packers and operators. Use this one when the order is for dedicated operators, when the client runs a driving evaluation before accepting anyone, or when the truck is specialized. If you are filling the shift lead who trains and evaluates operators, use warehouse supervisor screening questions.
Match the truck class before you match the candidate
"Forklift" covers machines that drive very differently. OSHA's powered industrial trucks eTool groups the common ones into seven classes (as of September 2026). Ask the client which class, make and attachment the operator will run, then screen against that. A candidate with five years on a propane sit-down may struggle for a week on a stand-up reach truck in 10-foot aisles.
| OSHA class | What it covers, in site terms | A question that tests it |
|---|---|---|
| Class I: electric motor rider trucks | Electric sit-down counterbalance trucks, common indoors on docks and in manufacturing | "Were you on the dock, in racking, or feeding a production line?" |
| Class II: electric motor narrow aisle trucks | Stand-up reach trucks, order pickers, turret and swing-mast trucks in high racking | "How high was the top beam, how wide were the aisles, and was it wire-guided or free-steered?" |
| Class III: electric motor hand or hand/rider trucks | Walkie and rider pallet jacks, walkie stackers | "How many pallets a shift, and did you double-stack on a rider jack?" |
| Class IV: internal combustion, cushion tires | Propane or gas sit-downs on smooth floors, often in older warehouses and plants | "Who changed the propane cylinder, and what did you check when you did?" |
| Class V: internal combustion, pneumatic tires | Outdoor and yard trucks: lumber yards, building supply, steel, container work | "Were you on gravel or paved yard, and what loads were you moving?" |
| Class VI: electric and internal combustion tractors | Tuggers pulling carts or trains, common in manufacturing and airports | "How many carts did you pull, and what was the route?" |
| Class VII: rough terrain forklifts | Telehandlers and straight-mast rough terrain trucks on construction sites | "Did you place loads on upper floors or roofs, and who was signaling you?" |
Attachments change the job again. Clamp trucks for paper rolls or appliances, push-pull and slip-sheet attachments, carpet poles and drum handlers all change how a load is picked up and how much the truck can safely carry. The standard at 29 CFR 1910.178(a)(5) expects a truck with non-factory attachments to be marked with the combined weight at maximum elevation. If the order involves an attachment, it is a knockout question, not a nice-to-have.
What "certified" means, and who does what for a temp
Under 29 CFR 1910.178(l), the employer must make sure each operator is competent before they operate, except for training purposes. Training combines formal instruction, practical training and an evaluation of the operator's performance in the workplace, carried out by someone with the knowledge and experience to train and evaluate. The employer certifies it with the operator's name, the training date, the evaluation date and who did the training or evaluation. Each operator is evaluated at least once every three years, and refresher training is required after unsafe operation, an accident or near miss, a poor evaluation, assignment to a different type of truck, or a change in workplace conditions.
For staffing orders, OSHA's Temporary Worker Initiative bulletin on powered industrial truck training sets out the split as of September 2026: the agency is generally responsible for generic training, and the host employer is in the best position to give site-specific training and the evaluation. Even when the agency supplies trained operators, the host must verify the training, train on its own trucks and conditions, and evaluate each operator. The bulletin also says the agency should take reasonable steps to find out what the host's training program covers.
Two practical consequences for your screen. First, "Do you have your forklift certification?" is the wrong question, because a certification belongs to an employer and a truck type. Ask what they drove, where and when. Second, find out from the client exactly what their evaluation involves before you screen, so you can tell the candidate and screen against it.
When a candidate has a card, record the truck type on it, the training date, the evaluation date and the employer or school that issued it. That is exactly what the client's evaluator will want to know, and it keeps you from describing a card as a license in your submittal.
Knockout questions
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| Are you at least 18 years old? | Yes. This is a legal requirement for the job, not a preference: the Department of Labor's Hazardous Occupations Order 7 bars minors under 18 from operating forklifts in nonagricultural work. | Any hesitation. Do not ask for a date of birth; ask only whether they meet the minimum. |
| This order is for a [class and type, e.g. stand-up reach truck] with [attachment, if any]. When did you last operate that exact type at work? | A site, a month, and a span: "At the frozen foods DC until March, about eighteen months on a Raymond stand-up." | Names a different truck when asked to describe it. Last used it "a while ago" and cannot give a year. |
| How many hours a shift were you actually on the truck? | A clear split: "Most of the shift on the truck; the last hour I cycled counts." | "Whenever they needed me" in a role that was mainly picking on foot. |
| The client runs a driving evaluation on [truck] before you start. Are you comfortable with that? | A plain yes, often with a question about which truck and what they will be asked to do. | Wants it waived because they "have a card". Evaluations are how the host meets its own duty. |
| The shift is [hours], with [overtime pattern]. Can you work that every week? | Yes, or a specific exception said now. | Asks immediately about a different shift. |
| The work is in [freezer, yard, outdoor dock] conditions. Can you perform the job in that environment for the full shift, with or without accommodation? | Yes, and often a detail from past work in the same conditions. | None from the answer. Do not follow up with medical questions. |
Questions by task: docks, racking, picking and yard work
Once the truck class matches, the task is where operators differ most. Ask the question for the task in the order, and let the candidate describe a normal hour. Operators who did the work volunteer sequence and small details; people who watched describe outcomes.
Dock and trailer work
-
"Walk me through unloading a trailer, from when it backs in to when you close the door."
- Strong answer: checks the trailer is secured (dock lock or chocks) before driving in, checks the dock plate and trailer floor, unloads in an order that keeps the load stable, scans or counts, stages by destination. OSHA's standard requires highway truck brakes to be set and the rear wheels chocked while they are boarded with a powered truck.
- Red flags: starts with "I drive in and grab the first pallet". Never mentions the trailer being secured.
-
"Floor-loaded or palletized, and how long did a trailer take you?"
- Strong answer: knows the difference, gives a time per trailer and what slowed it down (mixed SKUs, damaged pallets, a trailer loaded nose-heavy).
- Red flags: a time that does not survive arithmetic. See the rate section below.
Racking and narrow aisles
-
"What was the highest level you put away to, and what did you do differently at that height?"
- Strong answer: a beam height, and specifics: slower lift, tilt level before placing, checking the pallet is square on the beams, watching the load backrest, a spotter or camera where used.
- Red flags: no number for the rack height. "It's the same as low, just higher."
-
"Were the aisles wire-guided or rail-guided, or did you steer yourself?"
- Strong answer: knows which, and for guided aisles, how the truck enters the guidance and what happens at the aisle end.
- Red flags: cannot say, for a very narrow aisle order.
Order picking at height
-
"On the order picker, how did you tie off, and what did you check on the harness?"
- Strong answer: describes the harness, lanyard and the anchor point on the truck, and inspecting them before the shift.
- Red flags: "Sometimes we didn't bother on the low levels."
Yard, building supply and construction
-
"On rough ground or a slope, how do you carry the load and which way do you face?"
- Strong answer: load low and tilted back, speed down, load uphill on grades, avoids turning on a slope, knows the ground can change after rain.
- Red flags: no difference from driving on a warehouse floor.
-
"On the telehandler, how did you use the load chart, and who gave you signals?"
- Strong answer: reads capacity from boom angle and extension on the chart, uses outriggers or stabilizers where fitted, works with a signal person when the load is out of sight.
- Red flags: has never looked at a load chart. Places loads blind.
Pre-shift inspection and safety questions
Under 1910.178(q)(7), trucks are examined before being placed in service, at least daily, and after each shift where they run around the clock. A truck with a condition that affects safety is not placed in service. Operators who did this every shift describe it in order and without prompting.
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| Talk me through your pre-shift check on your last truck. | A sequence: forks and chains, mast, tires, fluid leaks, horn, lights, brakes, steering, seatbelt, battery or propane connection, data plate readable. Filled out a checklist or scanned it on the truck. | "The day shift checks it." Or a check that is only "I make sure it starts". |
| What did you do the last time the check found a problem? | Tagged the truck out, told the lead, used another truck. Gives an example: a hydraulic leak, a horn that did not work. | Drove it anyway to hit rate. |
| When you leave the truck, what do you do? | Forks fully lowered, controls in neutral, power off, brake set, and wheels blocked on an incline. That is what 1910.178(m)(5) requires. | Leaves forks raised "for a minute" while they grab paperwork. |
| How did your last site keep pedestrians and trucks apart? | Marked walkways, horn at intersections and blind corners, eye contact before passing, no one under a raised load. | Treats pedestrians as their problem. |
| Have you been involved in a forklift incident or near miss? What happened afterwards? | A specific account, and the refresher training or change that followed. | A story that ends with them being blamed unfairly and nothing changed. Note: ask about incidents on the job, not injuries or medical history. |
| Did you change batteries or propane cylinders yourself? | Yes or no, and if yes, the steps and the PPE they wore. | Says yes but cannot describe how, for a site where operators swap their own. |
Rates, accuracy and damage
Most operator jobs are measured. Ask what the site measured, what their number was, and how it was counted (a warehouse management system, a labor management system, or a lead with a clipboard). Then check the number with arithmetic you can do on the call.
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| What was your rate target, in the site's units, and where did you usually land? | "Putaways per hour, target 25, I averaged about 28 once I learned the building." | Never knew their rate in a building that posted it every hour. |
| How was accuracy measured, and what happened when you put a pallet in the wrong location? | Knows the scan-to-confirm step and what the cycle count found. | "It never happened." |
| How did the site track product or rack damage, and what was your record? | Names the process (damage report, sign-off by a lead) and gives an honest answer. | Evasive, or blames the racking. |
An example of the arithmetic, with invented numbers: a candidate says they averaged 40 putaways an hour to racking about 25 feet high. Forty an hour is one every 90 seconds, including travel, scanning, lifting, placing and lowering. That is possible in a compact building with short travel, and unlikely in a large one. Ask them to describe a single putaway step by step and estimate the time. You are not accusing anyone; you are finding out whether the number is theirs or the site's target.
How forklift experience gets overstated
- The class is wrong. Years on a sit-down counterbalance described as "all forklifts", for an order that is stand-up reach in narrow aisles.
- The card is the experience. A training course with little or no operating time since. Ask how many shifts they have actually driven.
- Occasional driver as operator. A picker who moved the odd pallet when the operator was on break. Ask what share of the shift they were on the truck.
- Manual as powered. A manual pallet jack called "pallet jack experience" on an order for rider jacks.
- Height inflated. "High reach" that was two beam levels. Ask for the top beam height.
- The target as the result. A rate quoted from the wall chart, not what they hit.
- Attachment claimed from watching. "Clamp experience" from working next to a clamp truck.
Scoring, and the note to the site evaluator
Knockouts are pass or fail. Score the rest 0 to 2 each, so every operator on the order is compared the same way.
Pass or fail
- 18 or older.
- Has operated the ordered truck class and type at work, recently enough for the client.
- Has used the attachment, if the order requires one.
- Accepts the client's driving evaluation.
- Can work the shift and the environment, with or without accommodation.
Scored, 0 to 2 each (10 possible)
- Task match: has done the same task (trailers, racking height, picking at height, yard).
- Pre-shift inspection: describes a real check and what they do when it fails.
- Safe habits: leaving the truck, pedestrians, trailer securing, tie-off where relevant.
- Rate: knows their number and it survives the arithmetic.
- Recency and volume: a large share of recent shifts on the truck.
Then send the client a short operator note with the submittal, so the evaluator knows what to check first. Copy this and fill it from your screen:
Operator: [name]
Truck experience: [class and type, make if known], [site], [months], [share of shift on truck]
Tasks: [trailers / racking to X ft / order picker at height / yard]
Attachments: [none / clamp / push-pull / other]
Training record held: [employer or school], trained [date], evaluated [date], truck type [type]
Last rate reported: [number and unit], measured by [WMS / LMS / lead]
Pre-shift check: [described fully / partly]
Candidate's own gap: [e.g. "has not driven a turret truck; used reach trucks only"]
Available for evaluation: [dates and times]That note is the difference between an evaluator who starts from scratch and one who tests the right thing in ten minutes. It also protects you: if the candidate fails the evaluation, your note shows you screened for the right truck and passed on what you learned.
When you run a dozen of these calls in a morning, truck types and rack heights are the details that get swapped between candidates. Interview Signal keeps the transcript on your computer and ticks off the knockout questions as you cover them, so the operator note is written from what each person actually said.
Questions people ask
Can a staffing agency certify its own forklift operators?
An agency can train and evaluate operators, and OSHA's Temporary Worker Initiative bulletin on powered industrial trucks says the agency is generally responsible for generic training. The host employer must still verify that training, give site-specific training, and run its own workplace evaluation of each operator before they drive at the site.
How old does a forklift operator have to be?
At least 18 for nonagricultural work. The Department of Labor's Hazardous Occupations Order 7 bars minors under 18 from operating forklifts, so asking whether a candidate is 18 or older is a job requirement you can ask about directly.
Is a manual pallet jack experience relevant to a forklift order?
It shows the candidate has worked around pallets and docks, but it is not powered truck experience. OSHA's standard covers trucks powered by electric motors or engines, and the closest powered equivalent is a Class III electric pallet jack or rider jack.
What if the candidate's forklift card is from a school rather than an employer?
Treat it as evidence of formal instruction, not of competence at a site. Ask how many hours they have operated since, on what truck, and doing what. The client's evaluator will decide whether they can drive, so pass on what you learned rather than the card alone.
