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.
