Chapter 7: Signs, signals, markings and railroad crossings
Wyoming sign shapes and colors, overhead lane signs, use of lanes, pavement markings and highway-rail crossings.
Why this chapter matters
The Wyoming written test includes identifying signs by shape, color or symbol, and recognizing signals and pavement markings.
Signs
- Shapes matter: you can read a sign's shape even when fog or darkness hide its words. Diamonds warn of hazards; rectangles give regulations such as speeds and directions.
- STOP is an eight-sided red sign; YIELD is a downward triangle.
- Warning signs are yellow diamonds; work zone signs are orange.
- A red circle with a slash forbids what it shows.
- An overhead or pavement arrow with ONLY means you must go that way.
Use of lanes
- On a two-lane road, keep right and yield the left half to oncoming traffic.
- With three or more lanes your way, the middle lanes usually flow best; the left lane is for faster traffic, passing and left turns; the right for slower traffic and right turns.
Pavement markings
- White lines separate traffic going the same way; yellow lines separate opposite directions.
- Broken lines: passing or lane changes allowed when clear.
- Solid white: lane changing is hazardous.
- Solid yellow on your side: no passing or lane changes, except to turn left into or out of an alley, private road or driveway.
- Double yellow: no passing either way.
Railroad crossings
- Crossbucks are yield signs: slow, look and listen, and stop if a train comes. A plaque shows the number of tracks.
- Advance warning signs and RXR pavement markings come first; stay behind the stop line.
- Stop for flashing lights; with gates, stop before the gate area and wait until they rise and the lights stop.
- Never drive onto a crossing unless you can clear it, never race a train and never pass at a crossing.
- If you stall on the tracks, get everyone out and away at once and call 911.
Frequently asked questions
What does a solid yellow line on my side mean?
No passing or lane changing, except to turn left into or out of an alley or driveway.
Is a railroad crossbuck a stop sign?
It is a yield sign. You must yield to trains and stop if one is approaching.
