Final answer:
The correct action when entering a main road from a private road or other non-main road is to come to a complete stop and give the right-of-way to all other users of the main road, including vehicles, bikers, and pedestrians.
Step-by-step explanation:
When entering a main road from a private road, driveway, or an unpaved road, you must come to a complete stop and then give the right-of-way to pedestrians, bicyclists, or vehicles on the main road. This ensures not only your safety but also the safety of those who are already on the main road.
Areas near campuses can be particularly hectic due to high pedestrian traffic, and a traffic signal at such intersections can help manage the flow and enhance safety. In scenarios with ambiguous signs or in emergency situations, such as transporting a pregnant woman to the hospital at 4 AM, judgement and adherence to traffic laws, balanced with the urgency of the situation, is important. Always remember that when crossing roads, especially in cities with a speed limit of 60 km/hr, calculate that you need to cover a safe distance, such as walking 4 meters further than the car's width, before the car reaches you for safe crossing.
