Tennessee Road Sign Practice Test

How road signs are tested in Tennessee

Road sign questions are part of the Tennessee written knowledge test (30 multiple-choice questions, 24 right to pass). Know the signs well and those questions become easy points.

Signs from the Tennessee Comprehensive Driver License Manual (March 2025 (MT3Q28)). What every kind of sign means, by shape and color: our road sign guide.

Signs the Tennessee Comprehensive Driver License Manual adds

• Warning Signs - Diamond Shape (Yellow)

  A reverse turn sign warns of two turns in opposite directions less than 600 feet apart; an advisory speed plate below a warning sign gives the recommended maximum safe speed. p. 38

• Right-of-Way Procedures

  At a T intersection, drivers on the road that ends must yield to traffic from both directions on the through road; when turning left, yield to oncoming traffic going straight or turning right unless you have a green arrow. p. 54

• Entering the Interstate

  A LANE ADDED sign means the on-ramp becomes a new lane, so entering traffic doesn't have to merge right away and interstate drivers should avoid moving right there; a MERGE sign means entering traffic must merge into the existing right lane. p. 68

• Sharing the Road with Slow Moving Vehicles and Equipment

  A reflective orange triangle on the back of a vehicle means it travels under 25 mph, such as farm or construction equipment. p. 111

• Octagon Shape — Stop

  At a stop sign, stop completely without going past the crosswalk; if you can't see cross traffic from there, move forward carefully until you can, and go only when safe. An ALL WAY plate means everyone approaching must stop. p. 36

• Triangular Shape — Yield

  A yield sign means slow down and yield to traffic in the intersection or on the road you are entering. p. 36

• Rectangular Shape - Special Laws, Regulations or Important Information

  On a highway with more than one lane each way, a keep-right sign means drive in the far right lane unless passing a slower car or turning left; never straddle lanes or drive slowly in the center lane. p. 37

• Regulatory Signs

  A red circle with a slash over a symbol means that action is not allowed. p. 37

• Work Area Signs

  A flashing arrow panel warns that a lane is closed; begin merging into the open lane well before you reach it. A LOW CLEARANCE sign shows the height from the road to the bottom of a bridge or overpass. p. 39

• Highway Flaggers

  Flaggers usually use paddles marked STOP on one side and SLOW on the other (red flags in emergencies); you must obey their directions, and they wear fluorescent orange or yellow-green clothing so you can see them. p. 39

• Color Codes on Highway Traffic Signs

  Blue signs mean: motorist services. p. 35

• Color Codes on Highway Traffic Signs

  Brown signs mean: recreation and cultural places. p. 35

• Handicap Symbol

  Parking spaces with the blue handicap sign are reserved for vehicles with disabled veteran or disability plates or a disability decal; anyone else parking there is breaking the law. p. 40

• Round Shape — Railroad Ahead

  At a round railroad warning sign, slow down and be ready to stop; never try to beat a train, because you'll usually misjudge its speed (more than 200 crashes a year happen at crossings). p. 36

• Broad “X” Shape — Railroad Here

  The crossbuck marks exactly where the tracks are, and a plate below it shows how many tracks there are; with two or more tracks, one train can hide another coming the other way, so make sure every track is clear before crossing. p. 36

• Warning Signs - Diamond Shape (Yellow)

  A school crossing sign means slow down and watch for children crossing the road. p. 38

• Intersection Warning Signs

  The Side Road Railroad Crossing sign warns that railroad tracks cross the side road very close to the intersection. p. 114

• Color Codes on Highway Traffic Signs

  Red is a background color only for STOP signs, ALL WAY plates, DO NOT ENTER and WRONG WAY signs and on interstate route markers; it's also used for YIELD sign lettering and the prohibitory circle and slash. p. 35

• Octagon Shape — Stop

  An eight-sided (octagon) sign always means stop. p. 36

• Triangular Shape — Yield

  A downward-pointing triangle sign means yield. p. 36

• No Passing Signs

  A pennant-shaped sign (a sideways triangle) marks a no-passing zone. p. 37
