A 3-minute lesson from the Indiana course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
At all-way stops and roundabouts, the rules for who goes first are set in advance. Learn them and you won't need to guess what the other driver will do.
Know the rule
An all-way stop works like a two-way stop: stop, look for oncoming traffic, and go when it's safe. The first vehicle to stop at the intersection is the first to proceed.
Approaching vehicles must yield to pedestrians in the crosswalk and to traffic in the roundabout. Pedestrians must never walk across the circulating lanes to the center island.
In a multi-lane roundabout, know which lane you need before entering (signs and pavement markings guide you), and don't change lanes in the circulatory roadway.
In a multi-lane roundabout, yield to large vehicles such as tractor-trailers and buses going through at the same time, slowing or stopping to let them pass safely.
In a multi-lane roundabout, if two large trucks approach at the same time, who yields?
The right-lane truck yields to the left-lane truck
The left-lane truck yields to the right-lane truck
Neither truck has to yield
The smaller truck always yields
Answer: The right-lane truck yields to the left-lane truck
If two large trucks are approaching or driving through a roundabout at the same time, the driver in the right lane must yield to the driver in the left lane.
