Checked 10/21/26
Traffic Signals and Pavement Markings: key points
- A flashing red light means the same as a STOP sign. A flashing yellow arrow lets you turn after you yield to oncoming traffic and pedestrians.
- If a signal is not working, treat the intersection as if there were a stop sign on every approach.
- Yellow lines separate traffic going in opposite directions. White lines separate lanes going the same way. If the yellow edge line is on your right, you are going the wrong way.
- Importance
- ★★★★☆ (4 / 5)
- Weight
- About 5 of 25 Rules of the Road questions (20%)

Question 1. You want to turn right. The light is steady red and this sign is posted next to it. What must you do?
- ① Stop, then turn right when the way is clear
- ② Turn right only if no pedestrians are present
- ③ Stay stopped until the light turns green
- ④ Turn right without stopping
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ Stay stopped until the light turns green
Key point: NO TURN ON RED: stay stopped until green
Normally you may turn right on red after a full stop. This sign reads NO TURN ON RED, so you must stay stopped until the light turns green, even if the way is clear.
Wrong choices
- Stop, then turn right when the way is clear: That is the usual rule, but this sign takes it away.
- Turn right without stopping: You may never turn on red without stopping first, and here you may not turn at all.
- Turn right only if no pedestrians are present: The sign forbids the turn whether or not people are crossing.
Question 2. What does a flashing red traffic light mean?
- ① Stop only if other cars are coming
- ② The light is about to turn green
- ③ Stop, then go when it is safe, the same as a STOP sign
- ④ Slow down and go through with caution
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ Stop, then go when it is safe, the same as a STOP sign
Key point: Flashing red = STOP sign
A flashing red light has the same meaning as a STOP sign. Come to a full stop, and go only when you can enter without getting in the way of other traffic.
Wrong choices
- Slow down and go through with caution: That is the meaning of a flashing yellow light.
- The light is about to turn green: A flashing red light does not count down to green.
- Stop only if other cars are coming: You must stop every time, as at a STOP sign.
Question 3. What do yellow lines on the road separate?
- ① Lanes of traffic going the same direction
- ② Parking spaces
- ③ Bicycle lanes from car lanes
- ④ Traffic moving in opposite directions
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ Traffic moving in opposite directions
Key point: Yellow lines: opposite directions
Yellow lines separate traffic moving in opposite directions. White lines separate lanes going the same direction.
Wrong choices
- Lanes of traffic going the same direction: Lanes going the same way are separated by white lines.
- Bicycle lanes from car lanes: Bicycle lanes are marked with white lines.
- Parking spaces: Parking spaces are usually marked with white lines.
Question 4. Traffic lights at an intersection are completely dark because of a power outage, and no officer is directing traffic. What should you do?
- ① Drive through if you are on the larger road
- ② Treat it as if there were a stop sign on every approach
- ③ Honk and go through quickly
- ④ Slow down but do not stop
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② Treat it as if there were a stop sign on every approach
Key point: Dark signal: treat as an all-way stop
When a signal is not working, treat the intersection as if a stop sign were posted on every approach. Stop, then take turns going when it is safe.
Wrong choices
- Drive through if you are on the larger road: Being on the bigger road does not give you the right of way at a dark signal.
- Slow down but do not stop: You must stop, not just slow down.
- Honk and go through quickly: Honking does not give you the right of way.
Question 5. What does a steady yellow traffic light mean?
- ① Speed up to beat the red light
- ② Stop, then go when the way is clear
- ③ The light is about to turn red, so stop if you can do so safely
- ④ Go, because yellow is the same as green
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ The light is about to turn red, so stop if you can do so safely
Key point: Steady yellow: about to turn red, stop if safe
A steady yellow light means caution: the light is about to turn red. Stop unless you are too close to stop safely; then go through with care. Never speed up to beat the red.
Wrong choices
- Speed up to beat the red light: Speeding up to beat a red light is dangerous and the opposite of the rule.
- Go, because yellow is the same as green: Yellow is a warning that green is ending, not the same as green.
- Stop, then go when the way is clear: That describes a flashing red light.
Question 6. You want to turn left and see a flashing yellow arrow. What may you do?
- ① Turn left without stopping, because oncoming traffic is stopped
- ② Stop and wait for a green arrow
- ③ Go straight only
- ④ Turn left after yielding to oncoming traffic and pedestrians
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ Turn left after yielding to oncoming traffic and pedestrians
Key point: Flashing yellow arrow: turn after yielding
A flashing yellow arrow means the turn is allowed, but you must first yield to oncoming traffic and pedestrians. Oncoming traffic may still have a green light.
Wrong choices
- Turn left without stopping, because oncoming traffic is stopped: Oncoming traffic is not stopped during a flashing yellow arrow.
- Stop and wait for a green arrow: You do not have to wait for a green arrow if there is a safe gap.
- Go straight only: The arrow allows the turn shown; it says nothing about going straight.
Question 7. You are driving toward the top of this picture on a divided highway. The solid yellow line is on your right and the solid white line is on your left. What does this tell you?
- ① You are in a two-way left-turn lane
- ② The road is about to narrow
- ③ You are traveling the wrong way
- ④ You are in the correct lane for passing
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ You are traveling the wrong way
Key point: Yellow edge line on your right = wrong way
On a divided highway the yellow line marks the left edge and the white line marks the right edge. If you see the reverse, with yellow on your right, you are traveling in the wrong direction. Pull to the shoulder when safe and turn around when the way is clear.
Wrong choices
- You are in the correct lane for passing: Passing lanes still have the yellow edge line on the driver's left.
- You are in a two-way left-turn lane: A two-way left-turn lane is in the center of the road, marked with yellow lines on both sides.
- The road is about to narrow: Edge line colors tell you direction, not that the road is narrowing.
Question 8. What does a flashing yellow traffic light mean?
- ① The signal is broken; treat it as an all-way stop
- ② Slow down and go through with caution
- ③ Stop and wait for green
- ④ Speed up to clear the intersection
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② Slow down and go through with caution
Key point: Flashing yellow: slow down and proceed with caution
A flashing yellow light has the same meaning as a warning sign: slow down and go through with caution.
Wrong choices
- Stop and wait for green: Stopping is required for a flashing red light, not a flashing yellow light.
- The signal is broken; treat it as an all-way stop: An all-way stop applies when a signal is dark, not when it flashes yellow.
- Speed up to clear the intersection: Speeding up is never the right response to a warning.
Question 9. What do white lines between lanes tell you?
- ① You must not change lanes there
- ② Traffic in those lanes moves in opposite directions
- ③ The lanes are for buses only
- ④ Traffic in those lanes moves in the same direction
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ Traffic in those lanes moves in the same direction
Key point: White lane lines: same direction
White lines separate lanes of traffic moving in the same direction. Single solid white lines are also used as the right edge line of the road.
Wrong choices
- Traffic in those lanes moves in opposite directions: Traffic going opposite ways is separated by yellow lines.
- The lanes are for buses only: Bus lanes are marked with signs and words, not just white lines.
- You must not change lanes there: A broken white line allows lane changes when safe.
Question 10. You want to turn left. The signal shows a steady red light on top and a green left arrow at the bottom. What may you do?
- ① Turn left with care; this is a protected turn
- ② Turn left only after oncoming traffic has passed, since you must yield to it
- ③ Go straight but do not turn
- ④ Stop and wait, because the red light controls all turns
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① Turn left with care; this is a protected turn
Key point: Green arrow with red ball: protected turn in the arrow's direction
When an arrow and a circular light are both shown, turning traffic follows the arrow and through traffic follows the circular light. A green arrow gives a protected movement, so you may turn left with care while oncoming traffic is stopped. Drivers going straight must stop for the red light.
Wrong choices
- Stop and wait, because the red light controls all turns: The arrow, not the red light, controls the left turn.
- Go straight but do not turn: The red light means through traffic must stop.
- Turn left only after oncoming traffic has passed, since you must yield to it: That describes a flashing yellow arrow; a green arrow means oncoming traffic is held.
