What is the correct behavior if you see a vehicle about to make a left turn in front of you?

Choosing to prepare to stop or yield is the correct response when you observe a vehicle about to make a left turn in front of you. This action is essential for maintaining safety on the road. Vehicles making left turns often require crossing oncoming lanes of traffic, which can create a situation where they may not see or anticipate your approach.

By being prepared to stop or yield, you position yourself to avoid a collision. This consideration allows you to assess the situation more accurately and respond to any potential hazards, such as the left-turning vehicle not completing the turn in time or misjudging their gap in traffic.

Accelerating to pass could lead to increased risk, as you may not know whether the turning vehicle has a clear line of sight or if there are pedestrians or other vehicles in the intersection. Honking could startle the other driver but is not a reliable means of preventing an accident. Continuing at the same speed may not account for the other vehicle's actions and could result in a dangerous outcome. Thus, preparing to stop or yield is the safest and most prudent choice.
