Final answer:
You should yield to another vehicle at an intersection if that vehicle arrived first, if the driver is on your right and you both arrive simultaneously, if the vehicle is already entering the intersection, or in all of these situations combined. Rules and traffic signals are essential for the safety of all road users.
Step-by-step explanation:
At an intersection, you should yield to another vehicle in the following situations:
- If the vehicle reaches the intersection before you.
- If the driver is on your right and reaches the intersection at the same time as you do.
- If the vehicle is just starting to enter the intersection.
- In all of the above situations.
These rules are in place to promote safety and reduce the risk of accidents. Traffic signals also play a crucial role in managing the flow of vehicles and pedestrians to prevent accidents and ensure that everyone can cross intersections safely.
Remember, yielding the right-of-way when necessary and obeying traffic signals are both critical for the safety of all road users, including pedestrians.
