When driving from alleys, lanes, or side roads onto a highway, what is required?

When driving from alleys, lanes, or side roads onto a highway, it's essential to prioritize safety and adhere to traffic laws. Stopping immediately and yielding to pedestrians is the correct action because it ensures that those crossing the street are given the necessary right of way, which is a critical part of safe driving practices.

This requirement reflects the broader traffic laws that prioritize pedestrian safety. Since alleys, lanes, or side roads often have less traffic and may not be as visible to drivers on highways, it's crucial to take extra precautions. Yielding to pedestrians helps prevent accidents in areas where vehicle and foot traffic may converge unexpectedly.

The other choices do not fully address the safety considerations that are essential when merging onto a highway. Yielding the right of way to motor vehicles is important, but it must also include an awareness of pedestrians who may be crossing in those areas. Signaling before merging is a necessary practice, but it does not replace the responsibility to yield to pedestrians. Lastly, driving without stopping if the road is clear neglects the critical consideration of pedestrian traffic that may be present before a driver enters the highway.
