Objective

---

To reinforce safe parking practices that prevent vehicle rollaway incidents, protect workers and bystanders, and ensure compliance with workplace transport safety requirements and applicable OSHA expectations. Participants will review hazard recognition, parking brake and wheel chock use, securing unattended vehicles, driver responsibilities, and emergency actions if a vehicle begins to move unexpectedly.

Introduction

---

Vehicle rollaway incidents are often sudden, violent, and fatal. A parked vehicle can move because of an unset parking brake, a transmission left in neutral, parking on an incline, poor maintenance, or a driver exiting before the vehicle is fully secured. One fatal incident involved a dump truck that rolled downhill after the driver set the trailer brake but not the truck parking brake; the driver tried to stop the truck from outside the cab and was pinned and killed. Another fatal case involved a flatbed truck parked on an incline with the transmission in neutral and an inoperative emergency brake, which rolled backward and struck the owner. These events show that rollaway prevention depends on disciplined parking procedures every time, not just when conditions seem risky. [1] [3] [3]

Presenter Note: Open by asking whether anyone has seen a vehicle creep, roll, or shift unexpectedly. Emphasize that most rollaway incidents happen during routine tasks when people become complacent.

Key Points

---

• 1\. Park as if the vehicle could move on its own: Every parking event must end with the vehicle fully secured before the operator leaves the cab. The driver should stop the vehicle, apply the service brake, place the transmission in the correct position, set the parking brake, shut off the engine, remove the key, and verify the vehicle is stable before exiting. Parking on a grade increases the risk dramatically, so the vehicle must be positioned to reduce movement potential and secured before any unloading, hitching, or dismounting task begins. [1]

[1] [1]

• Do not assume a brief stop is safe.
• Do not leave the cab until the vehicle is secured.
• Treat every parking location as if it could become a rollaway hazard.
• 2\. Parking brakes are not optional: The parking brake is the primary control that prevents unintended vehicle movement when the vehicle is unattended or partially unattended. Drivers must verify that the parking brake is functioning correctly and fully engaged before leaving the vehicle. A parking brake that is weak, out of adjustment, or not applied cannot be relied on to hold a loaded vehicle on a slope. Supervisors should require routine checks and immediate reporting of brake defects. [3]

[3]

• Test brake holding ability during pre-use inspections.
• Report any brake weakness, delay, or abnormal feel immediately.
• Do not operate a vehicle with a known brake defect.
• 3\. Wheel chocks add a critical second layer of protection: Wheel chocks are a backup control, not a substitute for the parking brake. They are especially important when parking on grades, on uneven ground, or when the vehicle will remain unattended. Chocks must be the correct size and placed so they can effectively immobilize the vehicle. When parking on an incline, use chocks as required by site rules and position the wheels to reduce the chance of runaway movement. [1]

[3] [3]

• Use chocks on the appropriate wheels for the vehicle and terrain.
• Inspect chocks for damage, wear, or improper size before use.
• Do not rely on a single chock if site conditions require more protection.
• 4\. Never try to stop a rollaway vehicle by hand or by climbing onto it: If a vehicle begins to roll, do not run after it, grab it, push on it, or attempt to climb into the cab from outside. These actions place the worker in the crush zone and can lead to being pinned, dragged, or struck. The correct response is to warn others, move to a safe location, and get emergency help. A moving vehicle can change direction, gain speed quickly, and trap anyone who gets too close. [1]

[1] [3]

• Stay out of the path of travel.
• Warn nearby workers immediately.
• Call for emergency assistance if anyone is in danger.
• 5\. Maintenance and inspection are part of rollaway prevention: Safe parking depends on equipment that is mechanically sound. Drivers and supervisors must inspect brakes, tires, and related systems before use and remove defective equipment from service when needed. Low tire pressure, brake defects, or poor maintenance can reduce holding ability and make a parked vehicle unstable. Regular inspections and prompt repairs are essential controls, especially for vehicles used on slopes or in heavy-duty service. [3]

[3] [4]

• Check tires for proper inflation and condition.
• Verify brake function during pre-use checks.
• Tag out or report defective equipment immediately.

Hazard Identification

---

The main hazards in vehicle rollaway prevention are not limited to the vehicle itself. They include the parking surface, the vehicle condition, the driver’s actions, and the presence of workers or pedestrians nearby. Identifying these hazards before parking or exiting the cab is the best way to prevent a serious incident.

• Parking on an incline or uneven surface: The vehicle can gain momentum and roll into people, equipment, structures, traffic, or drop-offs, causing crushing injuries or fatalities. [1]

[3]

(Risk: High)

• Parking brake not applied, not adjusted, or not functioning properly: The vehicle may move unexpectedly after the driver exits, leading to runover, pinning, or collision incidents. [1]

[3]

(Risk: High)

• Transmission left in neutral or vehicle not fully secured before exit: The vehicle can roll freely once the engine is off or load shifts, increasing the chance of a runaway event. [3]

(Risk: High)

• Attempting to stop a moving vehicle from outside the cab: The worker can be pinned, dragged, crushed, or struck by the vehicle or nearby objects. [1]

[3]

(Risk: High)

• Poor maintenance, worn components, or low tire pressure: Reduced braking performance and instability can make a parked vehicle more likely to move or tip, especially under load or on a grade. [3]

[3]

(Risk: Medium)

Presenter Note: Ask the group to name the places on site where rollaway risk is highest: slopes, soft ground, loading areas, trailer yards, and roadside parking. Reinforce that the hazard is often created by a combination of factors, not one mistake alone.

Control Measures

---

Use the hierarchy of controls to reduce rollaway risk. Engineering controls such as automatic parking brake systems and alarms can prevent human error. Work practice controls include standardized parking steps, chocking rules, and no-exit checks before leaving the cab. Administrative controls include training, inspections, and documented procedures. PPE does not prevent rollaway incidents, but high-visibility clothing and proper footwear support safe movement around vehicles and help workers maintain footing when working near equipment.

• Use a standardized safe parking procedure every time: Require drivers to stop, brake, shift, secure, shut down, remove the key, and verify the vehicle is stable before exiting. Make the sequence part of daily habits and supervisor expectations. [1]
• Apply wheel chocks whenever parking conditions require added protection: Use chocks on grades, uneven surfaces, or whenever the vehicle will be unattended. Ensure chocks are the correct size and placed to effectively immobilize the vehicle. [3]

[3]

• Turn the wheels toward the curb, berm, or side of the road when parking on a grade: Position the front wheels so that if the vehicle moves, it will roll into a curb, berm, or other barrier rather than into traffic or workers. [1]

[3]

• Inspect brakes, tires, and vehicle condition before use: Include parking brake function, tire inflation, leaks, and general condition in pre-use inspections. Remove defective equipment from service until repaired. [3]

[4]

• Train drivers and verify competency on parking and chocking procedures: Provide initial and refresher training, then periodically test knowledge and practical skill. Document training and keep records current so supervisors can verify compliance. [1]
• Consider engineering controls that reduce human error: Where practical, install electronic parking brake systems or alarms that alert the driver when the parking brake has not been set before exiting the cab. [1]

Safe Work Procedures

---

1. Before parking, choose the safest available location and avoid inclines whenever possible. If parking on a grade cannot be avoided, plan the parking position so the vehicle is protected from rolling into people, traffic, or drop-offs. [3]
2. Bring the vehicle to a complete stop, apply the service brake, place the transmission in the proper position, set the parking brake, and shut off the engine before leaving the cab. [1]

[1]

1. If parking on a grade, turn the wheels toward the curb, berm, or side of the road and apply wheel chocks as required by site conditions and company procedure. [1]

[3]

1. Before exiting, verify that the vehicle is stable and that no one is in the path of travel. Never leave the vehicle in a condition where it can roll unattended. [1]
2. If a vehicle begins to roll, do not attempt to stop it by hand, by pushing, or by climbing onto it. Move to a safe location and alert others immediately. [1]

[3]

Presenter Note: Walk the group through the parking sequence step by step. Ask participants to describe what they would do differently if the parking area is sloped, crowded, or poorly maintained.

Personal Protective Equipment (PPE) Requirements

---

• High-Visibility Clothing: Wear high-visibility clothing when working around moving vehicles, parking areas, or trailer yards so operators can see pedestrians and spotters more easily. High visibility does not prevent rollaway, but it reduces struck-by risk when vehicles are moving or when workers are guiding traffic. [6]
  • Use garments that are clean and visible.
  • Replace faded or damaged high-visibility items.
  • Wear it whenever you are in the vehicle operating area.
• Safety Footwear with Good Traction: Wear footwear that provides support and traction to reduce slips while mounting, dismounting, or walking on uneven parking surfaces. Good footing is important when using wheel chocks, checking tires, or moving around parked vehicles. [2]
  • Choose slip-resistant soles where conditions are wet, muddy, or oily.
  • Keep laces tied and soles in good condition.
  • Replace worn footwear that reduces traction.
• Gloves for Handling Chocks and Equipment: Use gloves when handling wheel chocks, coupling equipment, or inspecting vehicle components to improve grip and reduce hand injuries from sharp edges, dirt, or hot surfaces. Gloves should fit properly so they do not interfere with safe handling. [5]
  • Select gloves appropriate to the task.
  • Inspect gloves for wear before use.
  • Do not use damaged gloves.
• Eye Protection When Inspecting or Working Near Equipment: Wear safety glasses when inspecting vehicles, checking components, or working in dusty or debris-prone areas around parking locations. Eye protection helps guard against dust, dirt, and small particles during routine checks and maintenance. [5]
  • Use side protection where needed.
  • Keep lenses clean for visibility.
  • Match eye protection to the task hazards.

PPE is the last line of defense. It supports safe work around vehicles, but it does not replace parking brakes, wheel chocks, maintenance, or disciplined parking procedures.

Real-World Example or Case Study

---

In one fatal incident, a dump truck driver parked at the top of a slight incline, set the trailer brake, and exited the cab without setting the truck parking brake. The truck rolled downhill, the driver tried to climb back onto the running board to stop it, and he was dragged and pinned against a hillside. In another case, a flatbed truck parked on an incline with the transmission in neutral and an inoperative emergency brake rolled backward and killed the owner. The lesson from both events is clear: a vehicle must be fully secured before the operator leaves it, and no one should try to stop a moving vehicle from outside the cab. [1] [1] [3] [3]

Presenter Note: Use this example to reinforce that experience does not eliminate risk. Even experienced drivers can make a fatal mistake if they skip one step.

Group Discussion

---

Discuss the following questions:

1. What is the exact parking sequence required at our site before a driver exits the cab?
2. Where on our site are the highest rollaway risks, and what extra controls do we use there?
3. What should you do if you notice a vehicle parked on a slope without chocks or with the parking brake not set?

Presenter Note: Encourage workers to answer based on actual site conditions and company procedures. If possible, have them point out the safest parking locations and the areas where chocks should be staged.

Emergency Procedures

---

1. If a vehicle begins to roll, immediately warn nearby workers and clear the area. Do not attempt to stop the vehicle by hand or by climbing onto it. [1]
2. Call emergency services right away if anyone is struck, pinned, or trapped. Do not move the victim unless there is an immediate life-threatening hazard. [1]
3. If the vehicle can be made safe without exposing anyone to danger, isolate the area and use appropriate equipment or trained responders to stabilize the vehicle before rescue efforts begin. [1]

Questions and Answers

---

Questions are encouraged. If something in the parking procedure is unclear, now is the time to ask before the next shift starts.

• Q: Why is the parking brake alone not enough on a grade?

A: Because a parking brake can fail, be out of adjustment, or be overwhelmed by vehicle weight and slope. On grades, wheel chocks and proper wheel positioning provide additional protection against movement. [3]

• Q: What should a driver do before leaving an unattended vehicle?

A: The driver should stop the vehicle, secure it with the parking brake, shut off the engine, remove the key, and verify the vehicle is stable. If the surface is sloped or conditions require it, the driver should also chock the wheels and turn the wheels toward a curb or berm. [1] [3]

• Q: What is the correct response if a vehicle starts rolling away?

A: Do not chase it, climb onto it, or try to stop it with your body. Warn others, move to a safe location, and call for emergency help if anyone is in danger. [1] [3]

Summary

---

Recap of main points:

• Always secure the vehicle completely before leaving the cab, including the parking brake, transmission position, engine shutdown, and key control. [1]
• Use wheel chocks and proper wheel positioning whenever parking conditions, grades, or site rules require extra protection. [3]
• Never try to stop a rollaway vehicle from outside the cab; get clear and call for help. [1]
• Inspect and maintain brakes, tires, and related systems so the vehicle can safely hold its position when parked. [3]

Action Items

---

Specific actions participants should take:

1. Review and follow the site parking SOP every time you park, even for short stops. [1]
2. Inspect your vehicle before use and report brake, tire, or stability concerns immediately. [3]
3. Keep wheel chocks available and use them correctly when parking on grades or other high-risk locations. [3]
4. If you see an unsecured vehicle, stop work, warn others, and notify supervision before someone gets hurt. [1]

Remember: Park it, brake it, chock it, and never trust a vehicle to stay put on its own.

Report all hazards, near-misses, and incidents to your supervisor immediately.
