The Defensive Driving Tips say to look ahead at least how many seconds while driving on a city street?
-
A.
30 seconds
-
B.
4 seconds
-
C.
8 seconds
-
D.
12 seconds Correct
The answer is "12 seconds"
The tips set a 12-second minimum forward scan on ordinary streets so drivers see traffic patterns forming and have time to react. The manual notes that 12 seconds at 30 mph is a little over a block ahead. A 20 to 30 second scan is a separate rule for freeway speed.
The traps in the wrong answers
A. 30 seconds
Thirty seconds sits at the top of the freeway-speed range, not the general street rule. This answer confuses the general 12-second look-ahead with the 20 to 30 seconds required at freeway speeds.
B. 4 seconds
Four seconds is a following-distance figure, not the forward-scan distance the tips address. This answer confuses the 12-second look-ahead with the two- to four-second following distance.
C. 8 seconds
Eight seconds is the far end of the potential stopping zone shown in the same diagram, not the minimum forward-scan distance the prompt asks about. This answer grabs the highest number from the four- to eight-second potential stopping zone band on the diagram and treats it as the forward-scan minimum.
