Final answer:
At intersections where two vehicles arrive simultaneously, the driver on the left should yield to the driver on the right. Traffic controls may alter this rule, and pedestrian safety must also be considered, with traffic signals commonly used to allow safe crossing.
Step-by-step explanation:
When two vehicles approach or enter an intersection from different roadways at approximately the same time, the general rule of thumb is that the driver on the left should yield to the driver on the right. This is one of the fundamental rules of roadway etiquette and traffic regulations, designed to prevent accidents and ensure an orderly flow of traffic. However, the specifics can vary depending on traffic signals, stop signs, yield signs, or other traffic control devices present at the intersection.
Pedestrian safety is also a critical aspect of intersection safety. Intersections near campuses or other pedestrian-heavy areas might benefit from additional traffic controls like signals to ensure that pedestrians can cross safely. In the absence of traffic controls, vehicles must always yield to pedestrians who are legally crossing the road.
Finally, it is also important to adhere to the posted speed limit and be cautious while approaching intersections as many vehicles may speed through without due care. Traffic signals help in reducing this problem by forcing vehicles to slow down and prepare to stop or yield.
