What should a driver do if dashboard lamps signal a malfunction?

Answer: C — Pull over safely and investigate the issue

If dashboard lamps signal a malfunction, the appropriate action for a driver is to pull over safely and investigate the issue. This choice is correct because dashboard warnings are designed to alert drivers about potential problems with the vehicle's systems. Ignoring these signals or continuing to drive can lead to further damage to the vehicle, pose safety risks to the driver and others on the road, and increase the likelihood of a breakdown. Once the vehicle is safely stopped, the driver can diagnose the issue or, if necessary, call for roadside assistance after determining the situation. Taking immediate action as indicated by the dashboard signals is vital for maintaining both vehicle integrity and road safety.
