During hard braking, what is the main benefit of antilock brakes (ABS) on a bus?
Correct answer: They help prevent the skids that hard braking can cause.
Answer options
- AThey guarantee a shorter stopping distance every time
- BThey help prevent the skids that hard braking can cause Correct
- CThey help prevent the skids that sharp turns can cause
Why
When you brake hard on a slippery road, the wheels can lock and make the bus skid. ABS prevents the wheels from locking, which lets the driver keep control. It does not always shorten the stopping distance, and it cannot stop skids that come from turning too sharply.
