Texas Road Signs: 85 mph Limits, Wireless School Zone Ban & DPS Exam
What is the speed limit on Texas highways. can it really be 85 mph? Are cell phones banned in Texas school zones? What is the penalty for driving around a flood barricade in Texas? The TX DPS Driver License Division at dps.texas.gov/DriverLicense requires classroom driver education, knowledge exam, and driving exam. Limited-access highways post up to 85 mph. Wireless devices are prohibited in school zones. Driving around a flood barricade is a Class B misdemeanor. up to $2,000 fine and/or 180 days in jail. Work zone fines double when workers are present.

1. Texas Speed Limits Reach 85 mph: and the DPS Driver Exam Tests Every Sign Between the Gulf Coast and the Panhandle
Texas has the most diverse road environment in the project: Houston elevated freeway network, the Hill Countrys winding US-290, the Panhandles flat US-87, the Gulf Coasts US-77, and the trans-Pecos desert routes. The TX DPS Driver License Division at dps.texas.gov/DriverLicense or Austin TX 78773-0300 requires a classroom driver education course, knowledge exam, and driving exam. The handbook includes practice questions at the end of each chapter. study them all. Many limited-access Texas highways have speed limits of 75 up to 85 mph, the highest legally posted limit in the country.
2. Texas Sign Shapes: What the DPS Knowledge Exam Tests About Colors, Symbols and Slow-Moving Vehicle Emblems
Texas uses a reflective orange triangle on the rear of vehicles traveling at 25 mph or less, a slow-moving vehicle emblem that is tested on the TX exam. On the state vast highway network from El Paso to Beaumont, shape and color identify a signs message before the text is readable at high speed. Know every row in this table before your DPS knowledge exam.

6. Texas Traffic Signals: Church Bus Lights, School Zone Wireless Ban and What the DPS Exam Covers
Flashing red = stop sign. Flashing yellow = yield. The TX DPS exam covers all signal types: standard lights, arrow signals, flashing signals, and pedestrian signals. Texas uses church bus flashing lights. same legal meaning as school bus lights. Wireless device use is prohibited in school zones regardless of signal status.
Standard Traffic Lights
Steady Red
Come to a complete stop behind the stop line. Wait until green.

Proceed if the intersection is clear. You must still yield to pedestrians and cross traffic.
Green Arrow (left)
You may proceed only in the direction of the arrow. Oncoming traffic is stopped.
Yellow Arrow (no left)
The protected turn is ending. Prepare to stop or yield if you have not yet entered the intersection.
Red Arrow (no left)
Do not turn in the direction of the arrow. Wait for a green arrow or green light.
Green. no left arrow
Proceed straight or right. left turn not permitted on this phase.
Opposing Traffic Extended Green
Oncoming traffic has an extended green phase. wait before turning left.
Flashing Signals
Flashing Red
Treat as a STOP sign, come to a complete stop, then proceed when safe.

Key test point: Flashing red = stop sign. Flashing yellow = yield. Church bus flashing red lights = same stop requirement as school buses. Wireless devices prohibited in school zones. All tested on the TX DPS exam.
7. Texas Pavement Markings: Shared Left-Turn Lanes, Bicycle Lane Rules and Railroad Crossing No-Parking Zones
Yellow lines separate opposing traffic. White lines separate same-direction traffic. The TX DPS exam covers lane lines, road arrows, curb markings, and pavement symbols. including shared left-turn (center) lane rules for mid-block turns into businesses, bicycle lane markings, and no-parking zones within 50 feet of railroad crossings.
Line Colors
Yellow lines
Separate traffic moving in opposite directions
White lines

8. Texas Work Zone Signs: Fines Double When Workers Are Present: and Barricades at Flooded Roads Can Mean Jail Time
Orange warning signs mark every active construction and maintenance work zone in Texas. Fines double in a work zone when workers are present anywhere in the construction zone. A separate and more serious rule: driving around a barricade placed at a location where water is over any portion of a road is a Class B misdemeanor, punishable by a fine of up to $2,000 and/or up to 180 days in jail.
Road Work Ahead
Construction zone begins ahead. reduce speed and be alert

Channelizing devices (barricades)
Direct traffic around obstacles or closed areas
- You must obey warning signs, signals, and flag person instructions in Texas work zones.
- Texas work zone fines double when workers are present anywhere in the construction zone.
- Driving around a barricade placed where water is over the road = Class B misdemeanor, up to $2,000 fine and/or up to 180 days in jail. Never drive around these barricades.
- Disobeying any warning sign or barricade is a misdemeanor punishable by a $1-$200 fine even outside active work zones.
Key test point: Orange always means construction or work zone. If you see orange, reduce speed and increase following distance immediately.
9. Texas Railroad Crossings: Stop 15 to 50 Feet From the Nearest Rail and No Parking Within 50 Feet
At Texas railroad grade crossings, stop within 15 to 50 feet of the nearest rail when directed to do so by a flag person, flashing red lights, warning bells, or any other warning device indicating a train is coming. No parking within 50 feet of the nearest rail of a railroad crossing. Never stop on the tracks.
Advance Warning Sign
Railroad crossing ahead. the first sign you see. Begin slowing down.
RR Crossbuck Sign (X-shaped)
Located at the crossing itself. yield to trains. Treat as a yield sign if no gates or lights.
Railroad Crossing (at crossing)
Marks the exact railroad crossing location
Crossing Gates
Lower when a train is coming. never drive around or under a lowered gate
Pavement markings (X + RR)
Painted on the road surface before the crossing as an advance warning
Flashing Red Lights
A train is approaching, stop and wait. Do not proceed until lights stop and it is fully clear.
Stop Line
Texas requires stopping within 15 to 50 feet of the nearest rail; no parking within 50 feet of the nearest rail; stop before the gate lowers and remain until it raises
- Stop before the gate lowers when lights begin to flash. Remain stopped until the gates are raised and the lights stop flashing.
- Stop within 15 to 50 feet of the nearest rail when: directed by a flag person, flashing red lights or warning bells are active, or any warning device indicates a train is coming.
- No parking within 50 feet of the nearest rail of a railroad crossing.
- Never stop on or drive around a crossing gate while it is down.
Key test point: Texas stop zone = 15 to 50 feet from the nearest rail. No parking within 50 feet. Stop before the gate lowers. All tested on the TX DPS exam.
10. Texas School Zone Rules: Wireless Devices Prohibited and Fines for Passing a Stopped School Bus
Pentagon-shaped school zone signs in Texas designate areas subject to special speed limits. Use of a wireless communication device is prohibited in Texas school zones. When a school bus displays alternately flashing red lights, stop from either direction until the bus resumes motion, the lights stop flashing, or the driver signals you to proceed. Exceptions apply only for buses on a different road or in a controlled-access highway loading zone where pedestrians cannot cross.
School Zone
School ahead. be alert for children, reduce speed
School Speed Limit
Texas school zones carry special posted speed limits; wireless devices prohibited in school zones; school bus alternating red lights = stop from both directions
Speed Limit Lights Flashing
Speed limit applies only when the flashing lights are active
School Crossing Ahead
Crosswalk used by schoolchildren ahead. yield to crossing guard and students
- Texas school zones carry special posted speed limits. obey what is posted, not just a standard number.
- Use of a wireless communication device is prohibited in Texas school zones. This includes texting, calling, and any other wireless device use.
- When a school bus displays alternately flashing red lights, stop from either direction until: the bus resumes motion; the lights stop flashing; or the driver signals you to proceed.
- Exceptions: Bus is on a different road, OR on a controlled-access highway where the bus is stopped in a loading zone and pedestrians are not permitted to cross.
- Violating the school bus law can result in substantial fines and, if bodily injury results, criminal charges.
Key test point: The pentagon shape is used exclusively for school signs. No other sign category uses this shape. making it one of the easiest shapes to identify on the exam.
11. Texas Pedestrian and Bike Signs: Full-Lane Rights for Cyclists, FM Road Sharing and the Right-Turn Merge Rule
Pedestrians have right-of-way in Texas crosswalks. Texas cyclists have full-lane rights when the lane is too narrow for a car and bicycle to share side by side. and motorists must yield to cyclists the same as to other vehicles. When making a right turn, merge into the bicycle lane rather than turning across cyclists. Both sign types use fluorescent yellow-green and are tested on the TX DPS exam.
Pedestrian Crossing Sign
A marked crosswalk is ahead. watch for pedestrians crossing
Bicycle Crossing Sign
Cyclists frequently cross here. reduce speed and yield to bikes
No Bicycles
Bicycles are prohibited on this road or path
No Pedestrian Crossing
Pedestrians must not cross here
- Pedestrians always have right-of-way in Texas crosswalks. yield before entering the crosswalk area.
- Texas cyclists may take the full lane when: overtaking another vehicle, preparing to turn left, there are road hazards, or the lane is too narrow for a car and bike to share safely.
- When making a right turn, merge into the bicycle lane first rather than turning across bicycle traffic. This prevents the most common car-bicycle crash in Texas.
- At intersections, right-of-way rules apply equally to motor vehicles and bicycles. yield to cyclists as you would to any vehicle.
- Fluorescent yellow-green is used for both school and pedestrian/bike signs. the shape distinguishes between them.
Key test point: Pedestrians always have right-of-way at crosswalks. marked or unmarked. This rule appears on virtually every state DMV exam.
12. How to Pass Texas DPS Driver Exam: Practice Questions in Every Chapter and 4 TX-Specific Rules That Are Tested
- Practice questions in every chapter. The Texas Driver Handbook includes practice questions at the end of each chapter. Answer all of them. The actual DPS exam covers the same material. Visit dps.texas.gov/DriverLicense for the latest information.
- Wireless devices are prohibited in school zones. period. Not just while the flashers are active. The Texas sign reads "use of wireless communication device is prohibited in the school zone." This is a separate offense from the school zone speed limit violation.
- Work zone fines double when workers are present. Texas specifically ties the doubling to worker presence anywhere in the zone. not just when you see a worker. Drive as if workers are always present.
- Never drive around a flood barricade. A barricade placed where water covers the road is not a suggestion. driving around it is a Class B misdemeanor in Texas (up to $2,000 fine + up to 180 days jail). This is Texas-specific and tested.
- Texas has 85 mph speed limits. Many limited-access highways have speed limits of 75 up to 85 mph. the highest legally posted in the country. Always look for posted limits; do not assume a default speed.
- FM roads are unique to Texas. Farm-to-Market (FM) and Ranch-to-Market (RM) routes connect rural Texas. obey their posted limits and watch for farm equipment with slow-moving vehicle triangles (25 mph or less).
- Merge into bike lanes before right turns. Texas requires merging with bicycle traffic before turning right. not turning across it. This is tested.
- Railroad: stop 15 to 50 feet from nearest rail. No parking within 50 feet. Stop before the gate lowers.
- Flashing signals. Flashing red = full stop. Flashing yellow = slow and yield.
- Church buses same as school buses. Texas law treats church bus flashing red lights identically to school bus lights. stop required from both directions.
