Approximately 1300 tanker truck rollovers occur every year. These rollovers are the reason behind one in four accident-related truck driver deaths. This course emphasizes the importance of drivers paying close attention to the road and its conditions, as well as how their behaviors and decisions can factor in a rollover.

Learning Objectives

At the end of this module, you will be able to:

  • Describe what happens during a rollover
  • Identify four risk factors for rollovers
  • Identify how driver behavior can cause rollovers
  • Describe unsafe behaviors such as excessive speed
  • Describe how vehicle design can cause rollovers
  • Explain the impact of a high center of gravity
  • Describe load effects that can influence a rollover

Key Questions

The following key questions are answered in this module:

What happens during a rollover?
All vehicles have a point at which lateral forces cause them to rollover. The lowest value of lateral acceleration that causes a vehicle to rollover is called rollover threshold, which is measured in gravitational units (g). Vehicles with a lower rollover threshold take less force to flip over, meaning it is easier for them to rollover.

Why are trucks more likely to rollover than cars?
Unlike a car, that is more likely to skid than roll, trucks have an easier time rolling because of the truck and trailer's higher center of gravity.

What are the most common risk factors for a tanker truck rollover?
The most common risk factors for tanker truck rollovers are: driver behavior, vehicle design and performance, load effects, and road and weather conditions.

What contributes to 75% of all tanker rollovers, and how do you prevent it?
Driver error contributes to 75% of all tanker rollovers. To prevent driver error, plan and prepare your trip in advance, as well as avoiding unsafe behaviors such as: distractions, complacency, tailgating, road rage, fatigue, eating, daydreaming, driving under the influence, and speeding.

Why does the impact of having a high center of gravity attribute to tanker rollovers?
Tanker trucks sit higher on their wheels, giving them a higher center of gravity. When a vehicle has a high center of gravity relative to its width, it becomes less stable.

Sample Video Transcript

Below is a transcript of the video sample provided for this module:

All vehicles have a point at which lateral forces will cause them to rollover. The lowest value of lateral acceleration that will cause a vehicle to rollover is called its rollover threshold, which is measured in gravitational units or "g". Vehicles with a lower rollover threshold take less force to flip over, which means they are less stable. For example, standard cars typically roll at 1.2 to 1.3g, while pick-up trucks or jeeps roll at about 0.8g. A fully loaded tanker truck however, requires only 0.4g to roll. Unlike a car that will more likely skid than roll, trucks are more likely to roll. This is due to the higher center of gravity of the truck and trailer. Typically, during a rollover, the inside rear trailer tandem wheels lift first. The suspension and body of the trailer can absorb some twisting, but at a certain point the tanker begins to flip. The driver's first indication of rolling may be the image of the trailer lifting up in the side view mirror, giving little to no time to react.

Customer Q&A

I would like to have several employees take multiple courses. How can I set that up?

We're in the process of making bulk course and multiple user purchases easier. But for now, you can order multiple courses and contact us with details on who you'd like to assign courses to. We can set up each user's training plan and make sure everyone gets the eLearning assignments they need.

Can I get a free full-length preview of a course to see what this course covers?

While we do our best to offer details on course contents, we don't normally offer full-length previews. But please contact us with more details for a better understanding of what your organizaton needs and how we can help.

Do I get a certificate when I complete a course?

Yes. All of our courses allow you to print a completion certficate upon successfully passing the integrated test at the end of each eLearning course.

How do I log in to take a course that I have already paid for?

You'll receive an email with login details moments after you purchase your pay-per-view (PPV) course. Just click the login link and enter the user name and password provided.

Do you have courses in different languages?

Yes. While all of our courses are originally produced in English, we develop many courses in a growing number of languages, including Chinese, Dutch, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Tamil, and Thai. Available languages are normally displayed in the Course Details section on each course page.
