Texas Road Sign Practice Test

How road signs are tested in Texas

Road sign questions are part of the Texas written knowledge test (30 multiple-choice questions, 21 right to pass). Know the signs well and those questions become easy points.

Signs from the Texas Driver Handbook (Revised January 2026). What every kind of sign means, by shape and color: our road sign guide.

Signs the Texas Driver Handbook adds

• Warning Signs

  A low clearance sign shows the height of an underpass; don't go under it if your load is taller than the number shown. p. 27

• Warning Signs

  On a loose gravel road surface, go slowly enough to keep full control, and avoid sudden braking or sharp turns. p. 28

• Regulatory and Warning Signs

  The Exit Speed Advisory sign shows the advised speed for the highway exit ramp. p. 30

• Regulatory and Warning Signs

  A High Occupancy Vehicle (HOV) lane is reserved for buses and carpools during the hours shown on the sign, for example 6 a.m. to 9 a.m. on weekdays. p. 30

• Regulatory and Warning Signs

  A shoulder marked for emergency use is only for vehicles that must stop for a breakdown, tire trouble, running out of fuel or another emergency. p. 31

• Regulatory and Warning Signs

  A ROAD CLOSED sign means the road ahead isn't open to any traffic; look for a detour or another route. p. 31

• Automated Flagger Assistance Device (AFAD)

  An automated flagger assistance device (AFAD) is operated remotely so the flag person can stay out of the traffic lane; flashing arrow panels guide traffic into lanes and show that part of the road ahead is closed. p. 36

• Traffic Signs

  Brown signs mean: recreation and cultural places. p. 26

• Highway-Rail Grade Crossings Emergency Notification System (ENS)

  To report an emergency or a signal problem at a crossing, use the blue and white ENS sign: call the number on it and give the crossing's ID number. p. 22

  In a school zone, the posted speed applies when the yellow light is flashing, and signs may ban using a wireless communication device. p. 31

  A round railroad advance sign means a crossing is a few hundred feet ahead: slow down, be ready to stop, stop if a train is coming, and never try to beat it. p. 32
