There are a lot of road signs, so we better get started!

Oklahoma Traffic Signs

When it comes to traffic signs, there are a whole bunch of them with different purposes.

Some signs direct you on where to go and what to do.

Some signs give you regulations, such as speed limits.

Still, some signs warn you of hazards ahead.

Thankfully, it’s easy to identify what sign is which by its color and shape.

Oklahoma Traffic Signs – Colors and Shapes

Like colors, the shape gives you an idea of what the sign says. The shapes help you know what to do even if you’re far away.

Some of the most common signs you’ll see are red. These come in different shapes, but they will often tell you to stop or yield. Here are some examples of those signs:

Regulatory Signs

In Oklahoma, regulatory signs are usually black and white on a rectangle. They tell you what you can and can’t do.

When you see these signs, it means that the law requires you to follow them. Violating these laws may lead to a fine or points on your driver’s license.

Warning Signs

You can easily spot warning signs with their yellow color and diagonal shape.

As you already know, these warn you of a hazard ahead.

As a general rule, you need to slow down and be cautious when you see these signs.

Construction and Maintenance Signs

Orange signs are warning signs used for construction and maintenance.

Some areas will have yellow flashing lights telling you where you can pass.

If you see these signs, slow down and be cautious. Passing and speeding are not allowed. Also, look out for people working in the area.

Guide Signs

Guide signs are either green or white. They give information on roads and places. They also mark exits, parks, and distances from nearby places.

Here are some examples of guide signs:

Service Signs

Service signs, on the other hand, give directions to facilities. These include restaurants, lodging, gas stations, and handicapped parking spaces.

They will be in blue, rectangular signs.

Oklahoma Traffic Signals

Okay, now let’s move on to traffic signals.

As a driver, we’re pretty sure you’re familiar with these already.

But it’s still a good idea to go over it.

Traffic signals control the movement of traffic. They tell you when to stop and go. They also indicate when you can make a turn at the intersection.

Pedestrian Signals

Lane Control Signals

Oklahoma Pavement Markings

Other than road signs and traffic lights, pavement markings are there to help you know where you can pass and in what direction to go.

Conclusion

Yes, that was a lot.

But if you want to be a safe driver…

Or maybe you want to avoid those annoying tickets…

Or maybe you want to pass your permit test on the first try…

Then it’s important to study these Oklahoma road signs, signals, and markings.

Of course, you need to obey them, too.

Always be a safe and responsible driver!
