Difficulty: HardDefensive Driving and Hazard Anticipation

You are driving in the right lane of a four-lane urban roadway approaching an uncontrolled intersection. A stationary delivery van is parked on the right shoulder just before the intersection, partially obstructing your view of the adjacent sidewalk, while an aggressive driver tailgates your vehicle closely. As you approach, you notice the front wheels of an oncoming vehicle angled to execute a left turn across your lane. Which action demonstrates proper hazard anticipation and space cushion management in this situation?

  1. Gradually reduce speed, cover the brake pedal, scan under and around the stationary van for hidden pedestrians, and create extra forward space to manage the tailgater.Answer
  2. B
    Maintain your posted speed limit to assert your right-of-way over the turning driver and prevent the tailgating driver behind you from colliding with your rear bumper.
  3. C
    Flash your high-beam headlights to alert the oncoming vehicle that you have right-of-way, while maintaining your current speed and trajectory through the intersection.
  4. D
    Execute an immediate lane change into the left lane without slowing down, relying solely on your side mirrors to ensure the adjacent lane is clear.

Answer

Gradually reduce speed, cover the brake pedal, scan under and around the stationary van for hidden pedestrians, and create extra forward space to manage the tailgater.
The correct action combines multiple defensive driving tactics: slowing down early expands your reaction time, covering the brake reduces reaction distance, scanning beneath/around the obstructed area addresses hidden pedestrian risks, and increasing your front space cushion allows for gentle braking that prevents the tailgater from rear-ending your vehicle.

Step-by-Step Solution

1
Identify all active visual obstacles and surrounding traffic hazards.
Recognized three distinct risks: a blind spot behind the stationary van, an oncoming vehicle preparing to cut across the lane, and a tailgater limiting rear stopping margin.
Defensive driving requires identifying potential conflicts early before they enter your immediate path.
2
Apply space management techniques to control overall vehicle safety buffers.
Easing off the accelerator expands the front buffer, giving the tailgater behind more time to react if braking is required.
You cannot directly control the driver behind you, but you can control the space ahead of your vehicle to allow smooth, non-abrupt decelerations.
3
Prepare for sudden physical hazards using preventive control inputs.
Covering the brake reduces perception-reaction lag time while actively scanning pedestrian height profiles beneath and around the delivery van.
Covering the brake eliminates reaction distance delay, allowing immediate stopping power if a pedestrian steps out or the left-turning vehicle commits prematurely.
