A forklift expert explains why a truck tipped, struck someone, or dropped a load, and whether the operator, the employer, the maintenance program or the machine is responsible. Most of these cases come down to three things: whether the operator was truly competent on that truck in that workplace, whether the truck was safe to use that day, and whether the site kept people and trucks apart.
The governing rule for general industry is 29 CFR 1910.178, which OSHA calls powered industrial trucks and most people call forklifts 1 2. It also appears on OSHA's preliminary list of the top 10 most frequently cited standards for fiscal year 2026 3. This page covers trucks and warehouse handling. Cranes, hoists and aerial lifts are a separate specialty.
A NIOSH alert reported that 1,021 workers died in forklift-related incidents from 1980 to 1994, and that most fatalities occurred when a worker was crushed by a forklift that overturned or fell from a loading dock 4. It described overturns as the leading cause of forklift deaths, at about 25% of them 4. Those figures are old, but the mechanics have not changed. Pedestrians struck or crushed by a truck or its load are the other main group 4.
Stability explains the tipover. The appendix to the OSHA rule describes how almost all counterbalanced trucks rest on three points, forming a stability triangle, even if they have four wheels. When the combined center of the truck and load falls outside that triangle, the truck tips 1. An engineer works from load weight, load center, mast height, speed, turning radius and floor grade to show which of those moved the combined center too far.
The employer must ensure each operator is competent to operate the truck safely, as shown by completing the required training and evaluation 1. The rule has specific parts an expert will test against the file:
A certificate alone does not settle competence. The stronger question is whether the training addressed this truck type and this floor. A prior near-miss with no refresher is often more telling than the certificate.
Trucks must be examined before being placed in service, at least daily, and after each shift where they run around the clock 1. A truck found in need of repair or in any way unsafe must be taken out of service until it is restored to safe operating condition 1. So the inspection checklists and the repair history tend to be central, and a stack of identical, unsigned or pre-filled forms is something to look for.
Modifications and additions that affect capacity and safe operation may not be made by the user without the manufacturer's prior written approval 1. Added attachments, altered counterweights and removed guards raise this issue, along with the question of whether the capacity plate still matches the truck.
Design claims need care on the standard. The rule requires new trucks to meet ANSI B56.1-1969, and OSHA proposed in 2022 to update that reference to current editions 1 5. An expert should confirm which edition applied to the truck's build date, and should address what the current consensus standard says separately from what the regulation requires.
The travel rules are short and direct. A driver must slow down and sound the horn at cross aisles and other places where vision is obstructed, and must travel with the load trailing if the load blocks the forward view 1. No one may stand or pass under the elevated part of a truck, loaded or empty 1. Beyond the driver, the issue is site design: separated walkways, mirrors, traffic plans, dock edge protection, and chocks on highway trucks, which the rule requires to keep a trailer from rolling while it is boarded 1.
No license is specific to this work. Strong witnesses include safety professionals who have run warehouse programs and trained or evaluated operators, and mechanical engineers who have analyzed truck stability and design. Match the witness to the theory. A safety expert addresses training, supervision, and site controls. A mechanical engineer addresses stability, brakes, the mast, and alternative designs. An accident reconstructionist may address speed and motion, and a human factors expert may address visibility and perception.
Under 29 CFR 1910.178, an employer must ensure each forklift operator is competent as shown by completed training and evaluation, must evaluate performance at least once every three years, and must require refresher training after an accident or near-miss.

FAQ
Match the background to the theory. For training, supervision, and site controls, look for a safety professional who has run a warehouse program and evaluated operators. For stability or a design claim, look for a mechanical engineer who knows powered industrial trucks and the ANSI B56 standards. No license is specific to forklift work, so documented hands-on experience is the credential.
Under 29 CFR 1910.178, each operator's performance must be evaluated at least once every three years. Refresher training is required sooner in listed situations, including when an operator is observed driving unsafely, has an accident or near-miss, or when workplace conditions change in a way that could affect safe operation.
Almost all counterbalanced trucks rest on three points, called the stability triangle. A truck tips when the combined center of the truck and load moves outside that triangle. Speed in a turn, a raised load, an excessive load, a grade or a floor defect can each move it. An engineer works out which ones did so in the case.
The rule requires an examination before a truck is placed in service, at least daily, and after each shift where trucks run around the clock. A truck that is defective or in any way unsafe must be taken out of service until it is restored to safe operating condition.
Modifications and additions that affect capacity and safe operation may not be performed by the customer or user without the manufacturer's prior written approval, and the capacity, operation and maintenance plates must be changed to match. An expert will compare the truck as used against its data plate and its manufacturer's approvals.
In general, forklift expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic experience, safety credentials, engineering background, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
