Question

Difficulty: MediumDefensive Driving and Hazard Anticipation

While driving through a urban street with parked cars along the right curb, you observe exhaust fumes emitting from a parked vehicle and its brake lights illuminate briefly. What is the safest defensive driving response to this situation?

  1. Ease off the accelerator, cover the brake, and adjust your lane position slightly left within your lane to maintain a safe distance.Answer
  2. B
    Maintain your speed and sound your horn continuously to demand that the driver remain parked until you pass.
  3. C
    Accelerate quickly to pass the parked vehicle before the driver has an opportunity to enter your lane.
  4. D
    Swerve immediately into the oncoming traffic lane to give the parked car maximum space.

Answer

The safest defensive response is to reduce speed, cover the brake pedal, and shift slightly to the left within your lane to create space for potential hazards such as an opening car door or a pulling-out vehicle.
Recognizing exhaust fumes and brake lights on a parked car allows a driver to anticipate that the vehicle may pull out or that an occupant may open a door into the travel lane. Covering the brake and adjusting lane position creates both a time buffer and spatial buffer to respond safely.

Step-by-Step Solution

1
Identify early hazard cues
Recognize that active exhaust and brake lights indicate an occupied vehicle that may enter traffic or open its door.
Defensive driving requires scanning ahead and predicting potential actions of other road users.
2
Apply space management and speed control
Release the accelerator pedal, cover the brake to minimize reaction time, and adjust position to the left side of your lane.
Creating lateral distance and reducing potential stopping distance minimizes collision risk if the vehicle unexpectedly pulls into traffic.
