What should you do if you encounter a vehicle with malfunctioning stop lights?

Maintaining a safe distance from a vehicle with malfunctioning stop lights is the most appropriate action. This approach ensures that you have enough reaction time in case the driver suddenly brakes or makes an unexpected maneuver. When a vehicle lacks functioning stop lights, it can be difficult to anticipate the driver's actions, increasing the risk of a collision. Keeping a safe distance provides a buffer zone and enhances your ability to respond to any changes in traffic behavior effectively.

Choosing to ignore the situation could lead to dangerous outcomes, especially in heavy traffic or at high speeds. Signaling the driver to stop may not be effective since the driver might not see or understand your signal, and it could distract other drivers. Attempting to pass the malfunctioning vehicle at a higher speed introduces additional risk, as it does not address the unpredictability of the vehicle's movements. Thus, maintaining a safe distance is the best practice for ensuring the safety of all involved.
