Texas Road Signs (A Complete Guide)

Texas Road Signs

Road signs are there for one purpose — to keep everyone on the roadway safe. 

This is why it’s crucial to KNOW and OBEY all the Texas road signs, traffic signals, and even pavement markings. 

And this is why, here, we’re going to give you a complete guide to them all. 

We’ll go over the common signs, signals, and markings that you surely know about, as well as the not-so-common ones that might get you confused. 

There’s a lot to cover, so buckle up and enjoy the ride!

Texas Traffic Signals

Here’s something that all drivers (I hope) know about. 

Traffic signals are lights you usually find near intersections. They tell you when you can go forward, turn, stop, or slow down. 

Let’s go over the Texas traffic signals:

Steady Red LightStop before entering the crosswalk or intersection. You can turn right unless otherwise stated.
Flashing Red LightMake a full stop, look around, and proceed if it is safe to do so.
Steady Yellow LightWarns drivers that the light is about to turn red. If you haven’t entered the crosswalk or intersection, prepare to stop. 
Flashing Yellow LightYou can turn left but you must yield the right-of-way to oncoming traffic.
Steady Green LightYou can proceed if it’s safe to do so. 
Green Arrow Displayed with Red LightYou can only proceed in the direction the green arrow is pointing to. 
Left Turn on GreenWhile this isn’t a traffic light, this sign tells you that you can turn left on a green light. However, you need to yield the right-of-way to pedestrians and oncoming traffic. 

Pedestrian Hybrid Beacons

Did you know there are traffic signals for pedestrians, too?

If pedestrians want to cross, they can push a button to activate the Pedestrian Hybrid Beacon (PHB)

As a driver, you need to pay attention to the PHB and obey it. 

This is what the PHB will look like: 

Texas Road Signs

If there is no light, then you can proceed forward. 

If there is a yellow flashing light, that means a pedestrian hit the activate button. You need to start slowing down. 

If the yellow light becomes steady, that means the red light is about to come on. Prepare to stop.

A double red light means STOP. Let the pedestrians cross. 

Two flashing red lights mean the PHB is about to go dark again. If there are still pedestrians crossing, remain stopped. But if there are no more, then you can proceed. 

Texas Traffic Signs

When it comes to traffic signs, there are 5 kinds, namely:

  • Warning signs
  • Regulatory signs
  • Guide signs
  • Railroad warning signs
  • Construction and maintenance signs 

You can identify which sign is which by the color and shape. 

Let’s look at these first, then show you the different Texas traffic signs. 

Standard Sign Colors

Did you know that traffic signs are color-coded? 

This is so you already have an idea of what to do even if you haven’t read the text on the sign yet. 

RedStop, yield, or do what’s posted on the sign.
GreenYou can do the indicated movements. Also used for directions/guidance.
BlueMotorist services guidance.
YellowGeneral warning or caution.
OrangeConstruction and maintenance warning.
Retroreflective OrangeThis is used on various types of signs.

Horizontal RectangleFor guide signs.
Equilateral TriangleExclusively for yield signs.

Railroad Warning Signs

These signs warn you of a railroad crossing ahead and tell you what to do in this area.

Some railroad crossing areas will have gates and flashing lights. You are required to stop when you see these devices. 

In Texas, you are required to stop within 15-50 feet from the nearest rail when you see a person flagging for an incoming train, red flashing lights are turned on, or warning devices tell you of an approaching train. 

Construction and Maintenance Signs

These signs are often orange and diamond-shaped. They warn you of a work zone ahead that can pose hazards. 

Always, always slow down and obey the signs. 

Texas Road Signs

The signs are also often accompanied by channelizing devices and flaggers. These help direct the flow of traffic and separate the vehicles from the work zones. 

Texas Road Signs

When you encounter these devices and people, slow down and prepare to change lanes. Keep a reduced speed until you exit the work zone. 

The direction of devices with diagonal stripes also means something. 

If the stripes are sloping downward to the right, then you have to pass to the right. If it’s sloping downward to the left, then you should pass to the left.

Solid LinesThese lines are for pavement edge lines, shoulder markings, and lane use control.  

If it’s a solid yellow line at the side of the road, then it means driving past it is prohibited. 

If they’re double solid white lines, you cannot cross or pass.
