Final answer:
When vision is obstructed at an intersection, you should slow down and cautiously make the left turn after ensuring it is safe. Honking can alert other drivers, but does not replace the need for visual confirmation. Traffic rules and signals are crucial for road safety.
Step-by-step explanation:
If you are approaching an intersection with the intention to make a left turn after stopping for the stop sign, but your vision is obstructed by bushes blocking your right side, the safest option is to slow down and cautiously make the left turn, keeping an eye out for any vehicles. It is essential to ensure that the path is clear before proceeding with the turn. Honking your horn (option 3) can be used as an additional measure to alert potentially unseen vehicles, but it should not replace the need for visual confirmation that it is safe to proceed.
It's crucial to consider pedestrian safety and traffic regulations in this situation. For example, a traffic signal at the intersection could enhance safety for everyone by regulating vehicle speeds and providing safe crossing times for pedestrians. Instances like these highlight how traffic signals and rules (like stopping at a red light unless emergency circumstances apply) contribute to overall road safety.
