What do the colors mean on the Indiana road signs test?
The manual names seven colors, and each one tells you what kind of message you're reading:
- Red: a rule you must act on right away, like Wrong Way or Stop.
- Yellow: road conditions and hazards ahead. Fluorescent yellow-green: schools, pedestrians, bicycles, playgrounds and school bus routes.
- White: rules you must obey, like speed limits and No Turn on Red, and route markers.
- Orange: temporary conditions such as road work.
- Green: directions, exits and distances.
- Blue: services like gas, food and rest areas.
- Brown: parks and recreation or cultural sites.
Shapes, the way Indiana's manual explains them
Learn the circle and the pennant well. In Indiana's manual, round signs mean railroad crossings and pennants mean no passing, and the BMV's practice exam asks about both.
Eight sides: stop, and yield the right-of-way as the intersection requires
Triangle: slow down and be ready to stop for drivers or pedestrians
Circle: a railroad crossing is ahead
Pennant: no passing, posted on the left side of a two-way road
Five sides: a school area where children may cross
Diamond: a warning of road conditions or hazards ahead
Rectangle: a rule, information or, with a warning sign, an advisory speed
Advisory speed: a rectangle often posted with a diamond warning sign, for a curve's safe speed
Warning signs
Warning signs prepare you for road conditions and hazards ahead. Indiana's list in Chapter 6 also has buggy, golf cart, farm machinery and cattle warnings.
Stop ahead
Curve ahead with an advisory speed
Lane ends
Added lane
Divided highway begins
Two-way traffic
T intersection
Narrow bridge: be ready to stop for other vehicles
Low clearance
Deer
Bicycle
Traffic signal ahead
Regulatory signs
These set the rules for speeds, turns, lanes and parking. White signs give rules you must obey, and red ones need action right away.
Do not enter
Wrong way
One way
No U-turn
No left turn
Do not pass, posted on the right side of the road
Keep right
Slower traffic keep right
Left lane must turn left
Left turn yield on green
Do not block intersection
Reserved parking for people with disabilities
Work zone, school and railroad signs
Work zone speed limits are always at least 10 mph below the road's normal limit. A crossbuck with a stop sign means a full stop, and flashing lights or a lowered gate mean you wait until the warning ends.
Flagger ahead
Road work ahead
Detour
School bus stop ahead
School crossing
Crossbuck: on its own, treat it as a yield sign, and stop for a train
Emergency notification sign: the number to call about a blocked crossing
Slow-moving vehicle: can't go faster than 25 mph
Signals and lights
You may turn left on red only from a one-way street onto another one-way street, after a full stop. It's the first traffic question in the BMV's practice exam.
Flashing red: the same as a stop sign
Flashing yellow: slow down and go through with caution
Flashing yellow arrow: turn only after yielding to pedestrians and oncoming traffic
Steady yellow: your right-of-way is ending
Steady red: stop and wait for green and a clear intersection
Walk signal: pedestrians may cross, so turning drivers yield to them
