A 3-minute lesson from the South Dakota course. Read the rules and examples, follow the handbook page references, and check your understanding before you move on.
Lines, arrows, words and symbols on the road divide lanes, show when you may pass, mark turn lanes and walkways, and show where to stop. In the handbook's examples, yellow center lines divide two-direction roads and white dashed lines divide one-direction lanes.
Center and lane lines
Center and lane lines
Marking
Meaning
Double yellow line
Two-direction road: no passing in either direction
Solid and dashed yellow
Passing permitted only when the dashed line is on your side
When a sign or signal requires you to stop, stop behind the stop line, crosswalk, stop sign or signal. If there's a stop line before the crosswalk, obey the stop line first; if no crosswalk is apparent, stop before entering the intersection.
A center lane reserved for left turns (or U-turns where permitted) by traffic from either direction, marked on each side by solid and dashed yellow lines.
You need to turn left into a store on a street with a shared center lane. Signal, check that no one coming the other way is using the lane, move into it when safe, then turn once there's a safe gap in oncoming traffic.
