Where do you stop at a marked intersection when there is a solid red light?
Drivers facing a traffic control signal displaying a solid red light must bring their vehicles to a complete stop before the stop line or crosswalk that is directly in front of the vehicle.
Where does the car stop if there is no marked intersection?
If there is no stop line or crosswalk, drivers must stop before the intersection.
How long does the vehicle remain still at a solid red light?
Vehicles must remain stopped at the red light until it turns green, unless safely turning right after stopping.
What does a double solid red light mean?
A solid double red light has the same meaning as a single red light.
When are you allowed to turn right at a red light?
Unless a sign prohibits the turn, a driver may turn right at a red light after stopping completely before the stop line or crosswalk, if the turn can be made safely after yielding to other traffic.
When is a left turn permitted from a red light?
Unless a sign prohibits the turn, the only left turn permitted at a red light is onto a one-way street from a one-way street. This turn is only permitted after the vehicle is brought to a complete stop before the stop line or crosswalk, and if the turn can be made safely after yielding to other traffic.
What does a yellow light mean?
When a green light changes to yellow, it warns that the light will change to red immediately and drivers must prepare to stop or clear the intersection.
What does the driver do when there is a solid yellow light?
Drivers approaching an intersection with a solid (not flashing) yellow traffic control light must bring their vehicles to a complete stop before the stop line or crosswalk, unless a point has been reached at the intersection where stopping cannot be done safely.
Where does the driver stop if the light is solid yellow?
If there is no stop line or crosswalk, vehicles must stop before the intersection if the light is solid yellow.
What does the driver do if the light is solid yellow and the car is in the intersection?
Drivers already in the intersection and facing a yellow light must safely clear the intersection.
What does a solid green light allow?
Drivers facing a solid green traffic control light are permitted to travel through the intersection without stopping.
What can interrupt the flow of traffic from a solid green light?
The driver may be required to yield to oncoming traffic when turning left or to pedestrians in the crosswalk when turning right or left.
What should you anticipate when approaching a green light?
When approaching a green light, anticipate that it will turn yellow. A
“stale” green light means the light has been green for a while and will turn yellow soon.
Why would you pay attention to the pedestrian signals at an intersection?
A good tip is to check the pedestrian walk light at the intersection. If it shows the WALK symbol, the light will stay green. If it shows the DON’T WALK symbol, be ready to stop.
What happens where there is a solid green light and a flashing green arrow?
Drivers facing a traffic control light with a green arrow and solid green traffic control light may enter the intersection and proceed without yielding in the direction indicated by the arrow.
Drivers facing the green light may also proceed in the other directions when it is safe and legal.
What happens when there is a green arrow and a solid red light?
Drivers facing a traffic control light with a green arrow and a red control light may enter the intersection and proceed without stopping only in the direction indicated by the arrow.
What happens at a flashing red light?
Drivers facing a flashing red traffic control light must stop before the stop line or crosswalk.
Where does the driver stop if there is a flashing red light and there are no road markings?
If there is no stop line or crosswalk, drivers must stop before the intersection. Drivers should proceed only when it is safe and after yielding the right- of way. The flashing red light is treated like a stop sign.
