Final answer:
At an intersection with no signs or signals, give right-of-way to the vehicle on your right. Observe the speed limit and proceed cautiously to avoid potential accidents.
Step-by-step explanation:
When you arrive at an intersection that lacks traffic signs or signals at the same time as a vehicle to your right, the right-of-way rules apply. In such cases, it is generally established that the vehicle to the right should be given the right-of-way, meaning you should allow them to go first. This courtesy helps to prevent accidents and ensure a smooth flow of traffic. It is important to observe the posted speed limit and proceed with caution, especially in intersections where there may be vehicles that disregard speed regulations. A traffic signal in such situations would aid in controlling speed and enforcing the right-of-way more effectively.
