Indiana Road Sign Practice Test

How road signs are tested in Indiana

The Indiana knowledge test has a road sign part: 16 questions, and you need 14 right to pass that part. The 20-sign test here is a quick way to check you're ready for it.

Signs from the Indiana Driver's Manual (Published July 2026). What every kind of sign means, by shape and color: our road sign guide.

Signs the Indiana Driver's Manual adds

• Rectangular Traffic Signs

  Rectangular signs can show a regulation (such as a speed limit or No Left Turn), helpful information (route markers, destinations), or a warning such as an advisory speed for a sharp curve. p. 28

• Warning Signs

  Indiana's warning signs include a Buggy Warning sign, showing a horse-drawn buggy, for roads where horse-drawn vehicles travel; drivers should approach them with caution. p. 29

• School Zone Signs

  A School Bus Stop Ahead sign warns that a school bus may be stopped ahead to load or unload children. p. 30

• Speed Advisory Signs

  Speed advisory signs may accompany warning signs to show a safe speed, for example at a roundabout, on a ramp or at an exit. p. 31

• White Traffic Signs

  White signs show regulations drivers must obey, such as speed limits, and helpful information such as state highway markers; No Turn on Red is an example. p. 27

• Traffic Regulation Signs

  A DO NOT BLOCK INTERSECTION sign means you must not stop inside the intersection; wait until there's room on the other side. p. 31

• Supplemental Plaques

  Plaques under stop signs show which directions must stop: ALL WAY means every direction stops; CROSS TRAFFIC DOES NOT STOP means cross traffic won't stop for you. p. 32

• Approaching a Yield Sign

  A yield sign means slow down and yield to traffic in the intersection or on the road you are entering. p. 35

• Highway Construction and Maintenance Signs

  Orange construction signs warn of work zones; some give guidance, like Detour signs, and some state rules, like Worksite Added Penalties and worksite speed limits. p. 30

• Highway Construction and Maintenance Signs

  The Flagger Ahead sign warns that a flagger is controlling traffic in the work zone ahead. p. 30

• Flagger Signals

  Stop when a flagger holds an orange or red flag straight out into your lane, and proceed at reduced speed only when directed; with a paddle, stop or go slowly as its STOP or SLOW side shows. p. 47

• Work Zones

  Flashing arrow boards in work zones show lane closures or crossovers, with cones, barrels or markings outlining the path; a board that points neither way means use caution, but you don't have to change lanes. p. 47

• Blue Traffic Signs

  Blue signs mean: motorist services. p. 27

• Brown Traffic Signs

  Brown signs mean: recreation and cultural places. p. 27

• Traffic Guidance Signs

  Guidance signs tell drivers the type of road (interstate, US highway or state road), upcoming entrances and exits, and distances to destinations. p. 32

• Warning Signs

  A pedestrian crossing sign means slow down and yield to pedestrians in the crosswalk. p. 29

• School Zone Signs

  A school crossing sign means slow down and watch for children crossing the road. p. 30

• Crossbucks

  A crossbuck alone should be treated like a yield sign: stop if a train is approaching; with a stop sign, come to a complete stop and cross only when sure no train is coming. p. 48

• Railroad Crossing Safety

  At crossings with more than one track, after one train passes make sure another isn't coming on the other track; be aware of quiet zones where trains don't sound horns, and treat red signals flashing in all directions for street-running trains like any crossing warning. p. 49

• Pennant-Shaped Traffic Signs

  A pennant-shaped sign (a sideways triangle) marks a no-passing zone. p. 28

• Eight-Sided Traffic Signs

  An eight-sided (octagon) sign always means stop. p. 28

• Equilateral Triangle Traffic Signs

  A downward-pointing triangle sign means yield. p. 28

• Diamond-Shaped Traffic Signs

  Diamond-shaped signs warn of hazards or special conditions ahead. p. 28
