Driving SafelyQuestion 53 of 60
Why are combination vehicles more likely to roll over than they might appear?
a.Trucks with a high center of gravity can roll over at highway speeds on ramps even when they feel stable to the driver
b.Because the trailer is always empty
c.Because the tires are too wide
d.Because the brakes are too strong
Explanation
A loaded combination vehicle can roll over on a curve or ramp at a speed that feels safe because the driver cannot feel the trailer beginning to tip. The high center of gravity and trailer lag make rollover happen suddenly. Slowing well before ramps and curves is the safe practice.
