Two common types of interchanges are

A cloverleaf and diamond.

An interchange is a road junction where two or more roads cross over one another so as not to impede one another's traffic flow. Instead, the roads are connected through a series of connecting ramps. These ramps allow you to leave one road and enter another one safely, without disrupting the flow of traffic. Two common types of interchanges are cloverleaf and diamond. A disadvantage of cloverleaf interchanges is that vehicles entering the cloverleaf may have to merge with vehicles exiting the cloverleaf. The section of roadway where this occurs is known as a weave lane.

In the midst of finishing up learning on the older app, it told me to download this newer version. However, I didn’t want to have to go through all those questions again, so I simply finished reviewing on the old app and took the practice test on this newer app. Upon completion of the tests, it would not let me move forward or see my score! How should I know if I have done well enough to pass if I cannot see my own score?
