Question

Difficulty: MediumHydroplaning and Wet Road Traction Loss

Using cruise control while driving on a wet highway helps prevent hydroplaning by maintaining a consistent and steady wheel speed through standing water.

Answer: Answer

Answer

False. Drivers should never activate cruise control in rain or on wet roads, as automatic speed adjustment can cause wheel spin and loss of control during hydroplaning.
The statement is false. Safe driving rules prohibit engaging cruise control during rain or on wet pavements because the automated system will apply throttle when traction is lost, worsening hydroplaning and potentially causing a dangerous spinout.

Step-by-Step Solution

1
Examine the operating mechanism of cruise control on low-friction surfaces.
Cruise control maintains vehicle speed by automatically opening the throttle whenever speed drops.
Automated system adjustments lack sensors to detect hydroplaning and traction loss.
2
Analyze how cruise control reacts when hydroplaning begins.
When tires ride up on water and lose road contact, reduced resistance causes engine RPMs and wheel rotation to surge rapidly as the cruise control tries to sustain speed.
Sudden wheel spin destroys any remaining directional stability.
3
Identify the correct safety protocol for driving in rain and standing water.
Drivers must keep cruise control off so they can immediately ease off the accelerator manually to regain traction smoothly.
Manual control allows gentle deceleration without hard braking, which is essential for recovering from hydroplaning.
