The Most Common Signs
Above are some of the most common and most important intersection signs.
Intersection signs include the crossroad (A), side road (B), T-intersection (C), Y-intersection (D), and circular intersection signs.
If you understand which road you are on, it is pretty simple to distinguish the signs and understand what they mean. Remember, when roads are shown on signs like this you are always traveling on the road that starts at the bottom of the sign.
Side Road Sign
When you see a side road sign, you should watch for traffic entering the road you are on. There may also be vehicles turning into the side road.
If you see a T-intersection sign, the road you are on ends ahead. You must slow down and be ready to yield to traffic on the intersecting roadway. Then, you must turn left or right.
California Driver Handbook
For some strange reason, the California Driver Handbook insists on calling the side road sign (B) for T-intersection, which may confuse many readers.
