Regulatory signs give orders, not suggestions. Most are white with black letters or red with white letters. North Dakota uses three kinds of signs: regulatory, warning and guide. Learn the shapes too, so you can recognize a sign even from behind or in snow.

Stop
Stop sign: the only eight-sided sign

Know the rule

The Stop sign is the only eight-sided sign. Stop completely before the stop line or crosswalk. If there is neither, stop as near the intersection as possible where you can safely see traffic coming from all directions.

Yield
Yield sign

Know the rule

A Yield sign means you must yield the right of way: slow down, and stop if necessary.

Handbook p. 13 ↗

Know the rule

A Speed Limit sign shows the maximum speed permitted under ideal conditions. These signs are normally on the right-hand side of the road.

Handbook p. 13 ↗

Direction signs:

  • One Way: traffic flows only in the direction of the arrow
  • Wrong Way: you are going the wrong way on a street, freeway, or ramp
  • Do Not Enter: you may not enter that restricted road section

Know the rule

Signs that forbid an action are square, with black lettering on white and a red circle and slash over the action, such as No U-turn, No right turn, No trucks, or No left turn.

Know the rule

The rectangular Do Not Pass sign is on the right side of the road. The yellow pennant-shaped No Passing Zone sign is on the left side.

Know the rule

A No Turn on Red sign forbids right turns on a red light at selected intersections. Some intersections show it electronically.

Handbook p. 14 ↗

Know the rule

Two-way Left Turn Only signs mark a center lane for left-turning vehicles from either direction. The lane is not for passing or overtaking.

Handbook p. 14 ↗
Left turn yield on green
Left-turn signal sign: LEFT TURN YIELD ON GREEN

Know the rule

Some signs tell you how to read the traffic signal when you want to turn left. Pay close attention to each message to turn safely.

Handbook p. 14 ↗

Put it into practice

You want to turn left at a green light and see a LEFT TURN YIELD ON GREEN sign. You may turn on the green ball, but only after yielding to oncoming traffic.
