Final answer:
Yes, it is a good practice to reduce speed and be ready to stop at an intersection without a traffic signal to ensure safety and reduce accident risk.
Step-by-step explanation:
When two or more roads join and there is no signal or regulatory device, it is indeed a good practice to reduce your speed and be prepared to stop. This approach ensures the safety of the driver and passengers, as well as pedestrians and other road users. Without a traffic signal, vehicles may speed through the intersection without regard for the posted speed limit, increasing the risk of accidents. Furthermore, in such situations, pedestrian safety can become a major concern, as they must navigate traffic without the aid of signals that would allow them to cross at appropriate times. As demonstrated by a real-world example, the installation of a traffic signal can dramatically improve safety by controlling vehicle flow and enhancing pedestrian protection. In fact, the installation of traffic signals is often driven by an unacceptable number of accidents, which may include fatal ones, at an unsignalized intersection.
