You must obey all official signs, signals, and markings unless a police officer or road worker is redirecting traffic. Signs often use symbols or pictures instead of words. Each type of sign has its own color and shape so you can recognize it at a glance.
Getting Started
To operate a motor vehicle on Oregon highways or public roads, you must have a valid driving privilege. This course covers the requirements for a Class C non-commercial driving privilege, which is the standard license most drivers get.
Every time you take a test, you must first pay the test fee and show proof of identity, date of birth, and your current residence address. You can take tests at most DMV offices. The test fee is separate from any other DMV fees.
Regulatory Signs — Prohibitive
Traffic signs that prohibit certain actions or movements are red in color and increase safety by controlling the flow of traffic through intersections.

Yield — Triangle: Reduce speed and yield right of way. If needed, stop the same as you would for a stop sign.
