Difficulty: HardDefensive Driving and Hazard Anticipation

When driving in dense urban traffic behind a high-profile delivery truck, maintaining a standard 2-second following distance while focusing visual scanning exclusively on the rear brake lights of the lead truck provides adequate visual lead time to anticipate developing hazards in the road ahead.

Answer: Answer

Answer

The statement is False. Following a high-profile vehicle closely and fixating on its brake lights blocks visual lead time and limits hazard anticipation.
The statement is false because proper hazard anticipation behind a large vehicle requires opening up a larger space cushion (at least 4 seconds) to see around the vehicle and scanning 12–15 seconds ahead rather than fixating on the lead vehicle's brake lights.

Step-by-Step Solution

1
Analyze visual obstruction caused by large vehicles
High-profile vehicles block the view of traffic flow and road hazards ahead.
Defensive driving requires knowing what is happening 12 to 15 seconds down the road.
2
Evaluate following distance and scanning habits
A 2-second following distance behind a tall vehicle restricts sight lines, and fixating on brake lights creates target fixation.
Driver visual field becomes limited to the rear bumper of the truck rather than potential hazards ahead.
3
Determine the proper defensive driving behavior
The driver should drop back to a 4-second (or greater) space cushion and active scanning around the truck's perimeter.
Expanding space provides both early warning time and reaction distance.
