But the experts lay out these possibilities: *Air bags that do not deploy in low-speed collisions.

More recently, he developed a technique for studying low-speed collisions between charged molecules and electrons, mimicking chemical processes that occur in interstellar space.

There is a screeching of tires, and the sound of a low-speed collision, out on the street.

In 2003, The monorail was temporarily closed following a low-speed collision between two trains not carrying passengers.

The tests do not reflect on the overall safety of the two vehicles, but instead examine the billable damage incurred during low-speed collisions.

The shuddering steel plow blade took the brunt of the low-speed collision.

"They are complicated trade-offs between protection in a high-speed collision and in a low-speed collision," he said.

Two instances of operator forgetting to set the parking brake, resulting in low-speed collisions with fixed objects.

All the air bag deaths came in relatively low-speed collisions in which crash forces were not large enough to kill a passenger.

But some safety advocates said the Government was taking the wrong approach and should have instead required that the bags not open in low-speed collisions.
