Question

Difficulty: MediumHydroplaning and Wet Road Traction Loss

When driving on rain-soaked roadways, traveling directly in the tire tracks of the vehicle ahead increases the likelihood of hydroplaning.

Answer: Answer

Answer

False
Driving in the tire tracks of the vehicle ahead reduces hydroplaning risk because the leading vehicle's tires displace standing water, temporarily creating a clearer path with enhanced pavement contact for the following vehicle.

Step-by-Step Solution

1
Analyze how water accumulation causes hydroplaning on wet roads.
Hydroplaning occurs when a layer of standing water builds up between a vehicle's tires and the road surface, causing a complete loss of traction.
Excess water depth prevents tire treads from channeling water away rapidly enough.
2
Evaluate the effect of a preceding vehicle on wet road surface water.
As the front vehicle travels, its tires channel and displace standing water to the sides, temporarily reducing the water layer in those specific tracks.
Mechanical displacement by heavy rolling tires momentarily clears the pavement surface.
3
Determine the safety impact of driving within those cleared tracks.
Positioning your vehicle to roll in the established tire tracks allows your tires to maintain direct contact with the pavement more effectively.
Lower surface water depth in the tracks significantly diminishes the risk of hydroplaning.
