This would be talking about the Right Turn on Red. In the US the right turn on red is legal at all traffic lights, except where it is specified with a "No Turn on Red" sign (white background black lettering). You can legally turn right after you came to a complete stop at the traffic light, the traffic from the left has the right of way. There are times when you don't need to come to a complete stop when making the right turn on red. Some intersections have a lane median that separates the straight lanes from the right lanes (I don't know the technical term for it). These sometimes will have yield signs at the end, saying you have to yield to the traffic from the left. Really depends on the intersection whether you have to make a complete stop, if you only have to yield, or if you don't have to stop. Many so think at a regular 4-way intersection that the right turn on red is a yield, it's not, it's a stop, you must make your complete stop at the red light before proceeding to make the right turn on red, or if you can make it at all (No Turn on Red sign).
In all 50 states after coming to a complete stop at a traffic light if no cars are approaching you may turn right on red unless otherwise prohibited by a sign. The key is if no sign telling you not to turn right on red is present. Always look carefully before turning on red.
A. after slowing down and making sure it is safe
B. after coming to a complete stop unless otherwise posted
C. after yielding to pedestrians
Right turn on red after stop.
Stopped!
You must still come to a complete stop. Even if there is a flashing red light you must stop.
You can turn left at a red light only if signs specifically permit it. Usually, only right turns are permitted on red when clear.
Generally, a red light means "stop," but in many cities, it is permitted to make a right turn on red, with caution, if it is safe to do so (no other cars are coming). But as you have noticed, there are exceptions. If you see a sign that says "no right turn on red," that means that specific red light requires a full stop, and you may not make a right turn until the light changes to green. In other words, if you do not see any signs, you generally are allowed to make a right turn on red. If you do see a sign, you are not allowed to make a right turn on red.
Unless the lane is specifically marked as "Right turn permitted without stopping", yes. In any case you would still be required to yield.
You can turn right on a red light and a left red arrow. If there is a sign that says "no right turn on red" or it's a right red arrow, you can't turn right.
You must still come to a complete stop. Even if there is a flashing red light you must stop.
Yes, if it is safe to do so you may turn right on red after making a complete stop unless prohibited by a sign or the signal is a red arrow.
Yield to the right-of-way vehicles, until clear then turn cautiously
For left-hand drivers, depending on location: usually at any signallized intersection unless it is NOT permitted by a posted sign or a signal light that controls right turns. For right-hand drivers: never.
Typically, in states that allow right-on-red, it is legal unless there is a sign posted that says "No Turn On Red"
They are not exempt from such restrictions if they exist. If right turns on a red light are not permitted at that intersection, then that is applicable as much to a school bus as it is any other non-emergency vehicle.
