Which lights should be checked in conjunction with the four-way flashers?

The correct choice is to check the left and right turn signals along with the four-way flashers. This is important because the four-way flashers are designed to alert other drivers that a vehicle is stationary or moving slower than usual, often due to a hazard. Ensuring that the left and right turn signals are functioning properly in conjunction with the four-way flashers confirms that the vehicle is capable of indicating intentions for lane changes or turns. This is crucial for safety on the road, as proper signaling helps to prevent accidents and facilitates clear communication with other drivers.

Checking the other lights such as brake lights, clearance lights, parking lights, tail lights, headlights, and fog lights is essential, but they serve different functions. While brake lights are important for indicating stopping, and headlights for visibility, they do not directly relate to the vehicle's signaling capabilities like the turn signals do in conjunction with the four-way flashers. Thus, ensuring that turn signals operate correctly alongside the four-way flashers is key for safe and effective driving.
