Question

defensive driving - speed kills: speed management strategies

what is a major danger of panic braking at high speeds?

it improves the drivers reaction time
it increases fuel efficiency
it helps the vehicle stop faster
it can cause the vehicle to skid or roll over

Explanation:

Analyze the physical consequences of panic braking at high speeds

Sudden, forceful application of brakes (panic braking) at high speeds can cause the wheels to lock up, leading to a loss of traction. This loss of control often results in skidding, and the sudden shift in momentum or lateral forces can cause the vehicle to roll over.

Evaluate the given options

• "It improves the driver's reaction time": Incorrect, braking does not alter human cognitive reaction time.
• "It increases fuel efficiency": Incorrect, sudden braking wastes energy and decreases efficiency.
• "It helps the vehicle stop faster": Incorrect, locking the brakes and skidding actually increases stopping distance compared to controlled braking.
• "It can cause the vehicle to skid or roll over": Correct, this is a major physical hazard of high-speed panic braking.

Answer:

• It improves the driver's reaction time
• It increases fuel efficiency
• It helps the vehicle stop faster
• It can cause the vehicle to skid or roll over (Correct answer)
