According to the manual's steps for completing a turn safely, how far ahead of your turn should you signal?
-
A.
5 to 6 seconds before the turn.
-
B.
1 to 2 seconds before the turn.
-
C.
100 feet before the turn.
-
D.
3 to 4 seconds before the turn. Correct
The answer is "3 to 4 seconds before the turn."
The manual's turn-completion steps open with signaling 3 to 4 seconds before your turn. The 100-foot answer comes from Pennsylvania's separate signaling-distance law (100 feet under 35 mph, 300 feet at 35 mph or more), which drivers misfile as the turn-completion rule.
The traps in the wrong answers
A. 5 to 6 seconds before the turn.
Five to six seconds is the wet-road following distance, not the turn-signal lead time. This answer pulls in the wet-road following-distance figure because both rules count seconds ahead and get memorized side by side, so drivers blur them together.
B. 1 to 2 seconds before the turn.
A one to two second flash is too short to give following drivers useful warning under the manual's rule. This answer matches the quick flick many drivers actually give the turn stalk in day-to-day traffic, treating a brief tap as enough warning.
C. 100 feet before the turn.
The 100-foot figure is Pennsylvania's minimum signaling distance under 35 mph, not the seconds-based cue in the turn-completion steps. This answer comes from the driver's-ed rule of thumb to signal 100 feet ahead, which most drivers memorize as one number without the under-35-mph condition attached.
