Which action is essential before merging back into traffic after leaving an incident scene?

• A. Merging without signaling.
• B. Signal your intent to re-enter traffic.
• C. Speed up behind other vehicles.
• D. Turn off all warning lights.

Answer: (B)

Signaling your intent to re-enter traffic is essential because it clearly communicates what you plan to do and gives other drivers time to adjust their speed and position. Before merging, activate your turn signal, check mirrors and blind spots, and match your speed to the flow of traffic. When you find a safe gap, merge smoothly. Merging without signaling can catch other drivers by surprise and lead to crashes. Speeding up behind other vehicles removes the opportunity for a safe merge and increases risk. Turning off warning lights isn’t necessary for the merge and can reduce visibility, which is unsafe while you rejoin traffic.
