Preventing Rollovers Through Loading and Steering Control

Balance the truck before it moves

Follow the vehicle’s approved loading plan and respect gross vehicle, axle, shelf, and restraint limits. Place appropriate heavy packages low and distribute them so the truck is not unnecessarily heavy on one side. Do not solve an overload on one axle by creating another somewhere else; ask the fleet or loading team to resolve an uncertain arrangement.

A package can be within the truck’s overall weight capacity and still be poorly positioned or inadequately secured. FMCSA requires covered commercial vehicle cargo to be restrained against the movement addressed by its securement standards. 1 Use suitable restraints and sound anchor points rather than relying on neighboring cardboard cartons to hold a heavy object in place.

Think about the route after unloading

A stable arrangement at departure can change after several stops. Removing a large package can leave a gap that lets another slide. Collecting an unexpected pickup may add height or weight in the wrong place. Check those changes while safely parked, before the next curve or sudden stop tests the new arrangement.

Do not reach behind the seat or into the cargo area to steady a moving item. Find a safe place to stop, secure the vehicle, and correct the problem. If damaged equipment or insufficient restraint means the load cannot be made safe, contact dispatch and keep the truck out of service until the issue is resolved.

Avoid the correction that creates a larger problem

Looking away briefly can let a truck drift toward the edge of its lane. A sudden steering reversal may then produce a much larger sideways motion than the original drift. FMCSA’s rollover training specifically addresses driver control, load effects, and roadway hazards as connected risks. 2

Keep attention on the road and leave space from vehicles beside you. If the truck approaches or leaves the pavement edge, avoid an instinctive sharp return to the lane. Stabilize the vehicle and follow the recovery procedure taught for that vehicle and surface. The correct response depends on traffic, shoulder condition, available space, and speed; a universal emergency steering recipe is unsafe.

Make ordinary steering predictable

Use a steady lane position and look far enough ahead to recognize curves, stopped traffic, or lane narrowing early. Make small, deliberate corrections instead of repeatedly chasing the lane markings. Slow before tight maneuvers so the tires and suspension are not asked to handle a sudden change in direction at excessive speed.

Following distance is part of steering control. Space ahead can let a driver brake progressively instead of swerving around a stopped car. Avoid letting a tailgater push you into faster turns or shorter gaps.

After a significant cargo shift, unexpected lean, or loss of lane control, report what happened accurately. Include the load arrangement and road conditions, not just the steering event. A useful review can identify whether the next improvement belongs in loading, route planning, driver coaching, or vehicle maintenance.
