Answers

Answer:

1st one.

Explanation:

I think that because they the one who is going to get a ticket and also you will not gonna get in a car accident.

You should Remain stopped until all the crossing traffic has crossed through the intersection. Thus option A is correct.

What is traffic?

A road becomes congested when there are too many automobiles traveling along it at once. People must drive more slowly and closely together to fit more cars on the road if there is not enough room for everyone's vehicles.

You ought to stop and wait for all of the vehicle to pass through the intersection. I believe this since they are the ones who will receive a ticket and you won't be in an accident.

You must give way to a vehicle that reached before you since the first car really does have the right-of-way. The car to the rights still has the rights of way when three cars arrive at once, or the car to the left must move last. Therefore, option A is the correct option.
