Question 1489 in the bank

The reaction distance depends on:

  1. The vehicle’s speed only.
  2. The driver’s response only.
  3. Correct answer: The driver’s reaction time and the vehicle’s speed.
  4. The proper function of the vehicle's brakes.

Why this is the answer

The correct answer in the official bank: The driver’s reaction time and the vehicle’s speed.

Reaction distance is how far the vehicle travels from the moment the driver notices a hazard until they start braking. It equals speed multiplied by reaction time, so it depends on both: higher speed or a tired or distracted driver means a longer distance. The condition of the brakes affects the braking distance, not the reaction distance.
