Avoiding Rollover Collisions Customer Training Topic Ryder Safety & Loss Prevention Introduction Commercial motor vehicle rollovers are rare, but when they do occur, they are severe and often fatal. Most incidents in which a vehicle overturns are triggered by heavy braking and/or rapid steering movements. A drivers ability to negotiate a curve depends on:

Vehicle Speed Load Stability Curve Shape Vehicle Condition Roadway Condition Proprietary and Confidential 2 Facts & Statistics Rollover crashes constitute about one-fifth of all fatal crashes. Nearly three-fourths of occupants

killed in rollover crashes were not using restraints and about twothirds of them were completely ejected from the vehicle. Rollovers are more likely to occur on rural roads or highways. The narrower the road, the lower the margin for error. Proprietary and Confidential 3 Types of Rollover Collisions Lateral Force Rollovers Occur when a driver attempts to make a turn while traveling too fast. Excessive speed while turning causes the vehicle to continue on its original path and the vehicle rolls. Vehicles with high centers of gravity are at a greater risk for this type of rollover. Sideways Skid (and Trip) Rollovers Occur when a driver loses control and begins

sliding side ways. The tires hit a guardrail, curb, or other object. The tires get stuck, but the body of the vehicle continues moving causing the vehicle to rollover. Proprietary and Confidential 4 Types of Rollover Collisions Ramp Rollovers Occur when one side of a vehicle rides up onto an object (often a guardrail), while the other remains on the ground. These types of rollovers are typically caused by excessive speed, alcohol impairment and losing control of the vehicle. Side Slope Rollovers Occur when a vehicle rolls due to the slope of the ground beneath the vehicle. This usually occurs if a vehicle runs off of the road and up onto or over an embankment.

5 Factors Contributing to Rollover Collisions Road Conditions Slippery roads due to rain, snow, or ice Drowsiness Limited visibility because of fog or heavy precipitation Failure to anticipate bad road conditions Drop offs and Roadway barrier design

Vehicle Conditions Wheelbase Vehicle Weight Center of Gravity Proprietary and Confidential Driver Related Conditions Steering overcorrection Cargo Related Conditions Carrying more passengers than a vehicle is made to carry Poorly loaded or secured cargo cargo shifting may shift the center of gravity

6 Rollover Collisions and Seatbelts Approximately 75% of occupants killed in rollover crashes were not using restraints and approximately 60% of those occupants were completely ejected from the vehicle. Always remember to BUCKLE UP! Proprietary and Confidential 7

Avoiding Rollover Collisions Always ensure your vehicle is properly maintained. Perform quality inspections on a daily basis to identify any components that may be worn or broken. Always check and maintain tire pressure. This will improve traction, decrease your braking distance, reduce tire wear and decrease fuel consumption. Always drive safely for the weather and road conditions adjust your speed and be extra alert.

Proprietary and Confidential 8 Avoiding Rollover Collisions During inclement weather, slow down when the roads are covered in snow, ice and rain. Slow down on poorly maintained roads.

Slow down on winding or narrowing roadways. Always get enough rest between your trips to avoid fatigue find a safe place to pull over if you begin to feel sleepy Be a calm driver do not overcorrect in a panic Proprietary and Confidential 9
