Question

Difficulty: MediumHydroplaning and Wet Road Traction Loss

Anti-lock braking systems (ABS) eliminate the risk of hydroplaning when driving through standing water at highway speeds.

Answer: Answer

Answer

False
The statement is false because anti-lock braking systems (ABS) are designed solely to prevent wheels from locking during hard braking. ABS has no impact on hydrodynamic lift, which occurs when water pressure forces tires off the road surface due to excessive speed or standing water.

Step-by-Step Solution

1
Identify the primary function of an Anti-lock Braking System (ABS).
ABS automatically pumps the brakes during emergency stopping to prevent the wheels from locking up and skidding.
Clarifying system functionality helps evaluate whether it impacts hydrodynamic traction loss.
2
Examine the physical cause of hydroplaning on wet roadways.
Hydroplaning occurs when water builds up in front of the tire faster than tire treads can displace it, creating a wedge of water that lifts the vehicle off the road.
Hydroplaning is driven by vehicle speed, water depth, vehicle weight, and tire tread depth, independent of brake activation.
3
Evaluate the relationship between ABS and hydroplaning prevention.
Because ABS only operates during braking maneuvers to manage wheel rotation, it cannot prevent tires from lifting off wet pavement while driving.
The statement incorrectly attributes hydroplaning prevention to ABS.
