Ohio Road Sign Practice Test

How road signs are tested in Ohio

Road sign questions are part of the Ohio written knowledge test (40 multiple-choice questions, 30 right to pass). Know the signs well and those questions become easy points.

Signs from the Ohio Driver Manual (Online edition (October 2026)). What every kind of sign means, by shape and color: our road sign guide.

Signs the Ohio Driver Manual adds

• Traffic Signs

  Warning signs are usually yellow diamonds with black symbols that warn of possible danger ahead, such as a sharp turn, a downhill grade, limited clearance or a road that branches. Section 4

• Lane Pavement Markings

  With a double solid yellow line, don't drive left of center except to turn left or to pass a slow-moving vehicle such as a bicycle or one showing a slow-moving vehicle sign. Section 4

• Slow Moving Vehicles

  A reflective orange triangle on the back of a vehicle means it travels under 25 mph, such as farm or construction equipment. Section 9

• Speed Limits

  Freeways with paved shoulders inside municipalities are usually 55 mph; rural freeways 70 mph. Section 4

• Traffic Signs

  A yield sign means slow down and stop only if needed for other traffic; yield to all oncoming traffic. Section 4

• Multiple Lane Turning

  Where several lanes turn, choose your turning lane early and stay in it until the turn is complete. Section 5

• Turning on a Red Traffic Signal

  You may turn right on red unless a sign forbids it, after a complete stop and letting all crossing traffic and pedestrians clear. Section 5

• Work Zone Signs

  In work zones you must follow the directions of a flagger, slow down, be ready to stop, yield to workers and equipment, and not tailgate. Section 4

• Route Number Signs

  Route number signs use shape and color to show the type of road: interstate, U.S., state, city, county or local. Section 4

• No-Parking Zones / Handicapped Spaces

  Don't park in a space marked with the wheelchair symbol unless you have a removable windshield placard or an Accessible license plate; check signs and painted curbs for limits. Section 5

• Traffic Signs

  School zone signs tell you to observe the posted school speed limit during the restricted hours shown. Section 4

• Railroad Crossings

  At crossings with only markings or crossbucks, slow down and be ready to stop for a train; never stop on the tracks or try to beat a train; if there's a stop sign, everyone must stop. Section 5
