Why should you not rubberneck at crash scenes?

Answer: A — It causes traffic congestion

Rubbernecking at crash scenes should be avoided because it causes traffic congestion. When drivers slow down to look at an accident instead of focusing on the road ahead, it can lead to traffic backing up and potential further accidents due to sudden stops or distractions. This behavior can create a ripple effect, impacting the flow of traffic on the road and causing delays for other drivers. It is important for drivers to maintain their attention on the road to ensure their safety and the safety of others.
