Answer: (B)

Verified step by step guidance

1. Step 1: Understand the context of the problem, which is identifying common signs of impaired driving. Impaired driving typically involves behaviors that indicate reduced motor control, judgment, or reaction time.
2. Step 2: Review each option and consider whether it reflects impaired driving behavior. For example, 'Delayed response to traffic signals' suggests slower reaction times, which is common in impaired drivers.
3. Step 3: Analyze 'Erratic braking or acceleration' and 'Weaving or drifting within the lane' as these behaviors indicate poor vehicle control, which are also typical signs of impairment.
4. Step 4: Evaluate 'Consistently using turn signals correctly' and recognize that this behavior shows proper and attentive driving, which is not a sign of impairment.
5. Step 5: Conclude that the option which is NOT a common sign of impaired driving is the one that reflects correct and attentive driving behavior, i.e., 'Consistently using turn signals correctly'.
