Objective. Students will identify common commercial driving hazards—including struck-by, caught-between, slip/trip/fall, traffic control zone, and fuel-handling risks—and select the appropriate control from the hierarchy of controls for each scenario.
This lesson, its worked examples and its practice questions has not yet been verified by a certified examiner or master technician in the trade or by a certification or approval body. It is a study draft and may contain errors. Do not use it as instructions for work on a job site or on live equipment. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
Commercial driving is one of the most hazard-rich occupations in the United States. Drivers move between multiple high-risk environments every shift: public roadways, loading docks, fuel islands, construction work zones, and roadside breakdown locations. OSHA 10 training gives you a systematic way to spot dangers before they cause injury and to choose the right fix from a proven framework called the hierarchy of controls.
OSHA and the National Institute for Occupational Safety and Health (NIOSH) rank control measures from most effective to least effective:
1. Elimination — physically remove the hazard entirely.
2. Substitution — replace the hazard with something safer (e.g., use a lower-toxicity fuel additive).
3. Engineering controls — isolate people from the hazard with physical barriers, guards, or ventilation.
4. Administrative controls — change how work is done: policies, training, schedules, warning signs.
5. Personal Protective Equipment (PPE) — protect the worker's body as a last line of defense.
PPE is the least effective control because it does not remove the hazard—it only reduces exposure if worn correctly every time. Always try to move up the hierarchy before relying on PPE alone.
A struck-by event occurs when a moving object hits a person. At a loading dock, a forklift can strike a driver who enters the dock floor without authorization. On a roadside breakdown, passing vehicles can strike a driver who stands in the travel lane. Controls include high-visibility vests (PPE), cones and triangles placed per FMCSA regulations (administrative/engineering), and staying behind the guard rail whenever possible (engineering).
Caught-between injuries happen when a person is pinched, compressed, or crushed between two objects. Trailer coupling is a classic example: a driver's hand or foot can be caught between the fifth wheel and the kingpin during a drop-and-hook if the area is not clear. Never place any body part between moving vehicle components. Use a spotter and keep clear of pinch points.
Falls are a leading cause of injury at fuel islands, on trailer catwalks, and during cab entry and exit. Ice, spilled fuel, or wet dock plates create slip hazards. Three-point contact (two hands and one foot, or two feet and one hand, always in contact with the vehicle) is the standard administrative control for climbing in or out of a cab. Anti-slip dock plates and non-slip footwear are engineering and PPE controls.
Work zones on highways concentrate struck-by risk. Drivers entering a work zone must reduce speed, obey temporary traffic control devices, and maintain safe following distance. When a driver must exit the vehicle in or near a work zone—for an inspection, breakdown, or delivery—a high-visibility vest (ANSI/ISEA Class 2 minimum on most public roads, Class 3 in active work zones) must be worn immediately upon exit.
Diesel fuel creates fire, inhalation, and skin-contact risks. Static discharge can ignite vapors during fueling. Controls: bond the nozzle to the tank before fueling begins, do not top off the tank, wear nitrile gloves to prevent skin absorption, and avoid inhaling vapors by staying upwind. Know the location of the fuel island's emergency shutoff and fire extinguisher before you begin.
PPE does not eliminate hazards, but correct selection and use significantly reduces injury severity. Match PPE to the specific hazard:
Inspect PPE before each use. Damaged, cracked, or ill-fitting equipment must be replaced—never use compromised PPE.
Imagine your truck breaks down on a two-lane highway. Apply the hierarchy:
1. Elimination: you cannot eliminate passing traffic, but you can remove yourself from the travel lane entirely—move off the roadway.
2. Engineering: place reflective triangles at required distances behind the vehicle to create a visible buffer zone.
3. Administrative: call dispatch to report the breakdown and activate your four-way flashers immediately.
4. PPE: put on your high-visibility vest before stepping outside the cab.
This layered approach means that if one control fails (a driver does not see the triangles), another control (your vest) still protects you.
To earn your OSHA 10 card, you must complete all ten modules delivered by an OSHA-authorized trainer and pass the final written assessment at the required score. The card is issued by OSHA's authorized training program and is recognized by employers across the country. Keep the card in your records—some employers and job sites require proof before you can enter.
Answer each question, then check it. Nothing is recorded; this is your own practice.
