Preventing Rollovers- What Can You Do?

This summer the NHTSA issued a new rule requiring electronic stability control systems (ESC) on new commercial heavy trucks and large buses starting in 2017. It is believed that the new rule will prevent as many as 1,759 crashes, 649 injuries, and 49 deaths each year. In the meantime, what can you do to protect yourself? Many trucks currently have ESC, but for those that don’t (and even those that do), these tips could be lifesaving.

What Causes Rollovers?

The standard answer when it comes to rollovers is that the crashes are caused by driving too fast. This is a factor, but it is so much complicated than that. To prevent rollover, drive a safe speed of course, but also try some other strategies.

  • Pay Attention to Your Center of Gravity- The center of gravity is important in keeping things from toppling over. When driving a car, your center of gravity is almost always the same, but when driving a tractor-trailer, it can change depending on what you’re hauling and how it is loaded onto your trailer. Pay attention to your loads and drive carefully until you’re familiar with how a particular load is situated. Strap and secure properly. If a load isn’t fully secured it can shift as you drive, changing the center of gravity and potentially leading to a rollover. Drivers of cargo tanks should be especially cautious as liquids inside of the tank move as you do and can topple the tank rather easily.
  • Focus on the Road– Many drivers believe that rollovers are most common when entering and exiting the highway. While these are certainly times to be cautious, rollovers can happen at any time and are actually more likely on the roadway itself. Maintain focus at all times and look for hazards (sharp curves, soft shoulders, steep grades, hard berms, curbs, narrow driveways, limited visibility, etc.).
  • Watch Out for Vehicle Tripping– Vehicle tripping is a primary cause (95%) of single car rollovers, but is also a major contributing factor to tractor-trailer rollovers. This occurs when the tires strike a curb or fall into a soft shoulder. It often occurs during turns. To reduce your risk of tripping allow 3-4 feet between the tractor tires and the curb, giving room to the trailer’s tires should it shift a little during the turn.
  • Survey Before You Go- You can prevent rollovers before you ever get behind the wheel. Look at your expected route in detail before you head out. Look for hazards and areas where you’ll need to be extra vigilant. If you can, talk with others that have recently been on those roads and in the area for up to date advice on road conditions, weather, etc. Use your dispatcher and fellow drivers as valuable resources for knowing what’s ahead.
  • Don’t Get Complacent– Whether you’ve been driving for 1 year or 20, accidents can happen. Don’t let your familiarity with a particular route or your experience driving lull you into complacency. Driving a big truck is always dangerous and needs your full attention. Vigilance can prevent many rollovers.
  • Turn Left– When available and safe, left hand turns into a driveway are much safer than right hand turns. Turning left gives the rear tandem more room to track the tractor’s path.
  • Don’t Let Pre-Trip Inspections Slide– They take just a few minutes, but are so important. Always perform a thorough pre-trip inspection and don’t start driving until you’re confident that your truck is road-worthy and safe.
  • Speed Matters- Finally, remember that speed is an important factor in many rollovers. Speed limits aren’t always a safe speed to drive. Determine your speed based on road conditions and the weather and never exceed the maximum speed limit for an area. When approaching a turn, drive slower than the posted recommendations on the yellow safety signs. Safety experts recommend at least 10 mph less than the recommended speed for tractor/trailer combos. When going downhill, look at your speedometer rather than relying on feel. The bigger the vehicle, the slower it feels.
