chapter 1 section 16
Red Arrow
A red arrow is essentially a red light that tells you not to make a turn against the signal. You must wait until the light turns green or shows a green arrow before you proceed. This arrow only applies to drivers in the left or right turn lanes.
Flashing Yellow
A flashing yellow light tells you that you may go ahead, but with caution. Slow down and look both ways, stopping if necessary, before going through the intersection.
Red
A red light tells you that you must make a complete stop before the crosswalk or stop line (limit line). If there is no crosswalk or stop line, you must stop completely before you enter the intersection. You may make a right turn against a red light after you stop, provided that there is no sign prohibiting the turn and you yield to any pedestrians, bicyclists, and vehicles close enough to pose a hazard.
Flashing Yellow X
This signal above a lane indicates that you may use the lane, with caution, to make a left turn only.
Flashing Red
A flashing red light has the same meaning as a stop sign. You must first make a complete stop, and then you may proceed when the way is clear and you are given the right-of-way.
Green Arrow
A green arrow allows you to make a left or right turn, depending on where the arrow points. It also assumes you have unobstructed use of the highway, so you must be aware of oncoming vehicles, bicycles or pedestrians even if you are turning on a green arrow. Never assume that you have the right-of-way just because you have a green arrow. When a green arrow points downward, it indicates that you are allowed to drive in that lane.
Green
A green light tells you that you may proceed if you can do it safely. Look left, right, and then left again to make sure the way ahead is clear for you proceed. If there are any vehicles, bicyclists, or pedestrians already in the intersection, wait for them to clear the road before advancing. Beware of careless drivers who try to beat a red light. Do not enter the intersection if you cannot get completely across before the light turns red. If you block the intersection, you will get a traffic citation.
Yellow
A yellow light tells you to exercise caution because the right-of-way is going to change and a red signal is about to appear. You may proceed through the intersection on a yellow light, but only if you cannot stop safely at that point and you do not enter the intersection after the light turns red. The yellow light does not tell you to speed up so you can clear the intersection. Before you decide whether or not to proceed through the intersection on a yellow, you must consider several factors. These include the density of traffic, the speed of your vehicle as well as other vehicles, and road and weather conditions.
Red X
This signal indicates a lane where you cannot drive during certain hours.
Yellow X
This signal indicates that you should move out of the lane as soon as it is safe to do so.
broken traffic light
You should treat this intersection like a four-way stop. This means you must stop completely at the stop line, the crosswalk, or the entrance to the intersection. Check for hazards and proceed only when it is safe and you have yielded when necessary.
a pedestrian signal
lets pedestrians know when they may cross the road. Pedestrian signals may have WALK and DON'T WALK or a red upraised right hand and white walking figure. The red hand (or DON'T WALK), if steady, tells them they may not cross the street. If it is flashing, it warns pedestrians that the signal is changing and they must wait. The white figure (or WALK) indicates that they may proceed. If you are a driver and see the white signal, you must yield to any pedestrians crossing the street in your path. Pedestrian signals normally work in conjunction with regular traffic signals (red, yellow and green). Be especially cautious when making left and right turns.
