Final answer:
Drivers must yield to vehicles already on the main road when entering from a driveway or alley, following road safety rules and respecting the right-of-way.
Step-by-step explanation:
Drivers entering a main road from a driveway, alley, or roadside should yield to vehicles already on the main road. This is a fundamental rule of road safety to prevent collisions and ensure a smooth flow of traffic. When entering a main road, drivers must make sure it is safe to do so without causing disruption or danger to vehicles already traveling on that road.
Not only does yielding protect the safety of the driver entering the main road, but it also respects the right-of-way of the vehicles already on the main road, which may include those traveling at a legal speed or those navigating through intersections controlled by traffic signals.
Pedestrian safety is also a critical consideration, particularly in areas with heavy foot traffic such as near a campus, where students and other pedestrians need to cross roads safely.
When drivers are entering a main road from a driveway, alley, or roadside, they should yield to vehicles already on the main road. This means that they must wait until it is safe and there is no traffic coming before entering the main road. By yielding to vehicles already on the main road, drivers can prevent accidents and ensure a smooth flow of traffic.
