WASHINGTON (AP) -- Federal safety investigators are probing rollover accidents by tanker trucks carrying propane, gasoline and other hazardous materials.
The National Transportation Safety Board wants to know whether equipment similar to the stability systems required for cars would help prevent tanker rollovers.
The board is holding a hearing Tuesday on an accident that occurred last year in Indianapolis, when a propane tank truck hit a guardrail on a busy interstate, rolled over and exploded. A giant fireball could be seen miles away. No one was killed, but five people were injured.
There are an average of 1,265 cargo tank rollovers annually in the U.S.
