Final answer:
When entering a main road from a driveway, alley, parking lot, or roadside, slow down, stop if necessary, and check for pedestrians and oncoming traffic. Calculate the speed and distance of approaching vehicles, such as considering if a car is 28 m away, to ensure it is safe to enter or cross the road. Anticipate other road users' actions and make informed decisions for safety.
Step-by-step explanation:
When entering a main road from a driveway, alley, parking lot, or roadside, it is important to ensure the safety of oneself and others. Initially, slow down and prepare to stop before reaching the sidewalk or main road. Look both ways to check for pedestrians (like the woman pushing a baby stroller) and ongoing traffic. If there are cars stopped at an intersection, like the two cars you see, observe their signals to anticipate their movements. It is also crucial to be aware of any sudden, unexpected events such as an animal (e.g., a dog running out) that could potentially enter the roadway and impact safety.
If pedestrians are present, such as a walker with a stroller, yield to them before proceeding. Once the pedestrian path is clear, edge forward and check both directions for vehicles; consider their speed and distance to gauge if you have enough time to enter or cross the main road safely. For example, if a car is 28 m away, you would need a sufficient gap in traffic to enter or cross without causing the approaching car to slow down or swerve. Remember, in urban areas, the standard speed limit is 60 km/hr, thus calculating the necessary time and distance before moving onto the main road is essential.
