Signs, Signals, and Pavement Markings
Key Takeaways
- Tennessee sign questions often start with shape or color: octagon means stop, triangle means yield, round yellow means railroad ahead, crossbuck means railroad tracks here, diamond means warning, and fluorescent yellow-green marks school and pedestrian areas.
- A steady yellow light means prepare to stop if safe, a flashing red light works like a stop sign, and a flashing yellow light means slow down and proceed cautiously.
- Unless a sign prohibits it, Tennessee allows right turns on red after a complete stop and a full yield to pedestrians, bicyclists, and cross traffic.
- Yellow lane markings separate opposite-direction traffic; white lane markings separate same-direction traffic and mark stop lines, crosswalks, and lane boundaries.
- Double solid yellow lines prohibit passing from both directions, but a driver may cross them for a safe legal left turn into a driveway or side road.
Signs, Signals, and Pavement Markings
Tennessee uses signs, signals, and pavement markings to tell drivers what to expect before they reach the hazard. On the permit test, do not wait for a full sign picture. Shape, color, and line style are often enough to choose the next safe action.
Sign Shapes and Colors
| Control | Tennessee meaning | Driver action |
|---|---|---|
| Red octagon | Stop | Stop completely before the stop line, crosswalk, or intersection, then proceed only when safe. |
| Red-and-white triangle | Yield | Slow down, be ready to stop, and let conflicting traffic or pedestrians go first. |
| Round yellow sign | Railroad crossing ahead | Slow, look, listen, and prepare to stop before the tracks. |
| White crossbuck | Railroad tracks at this location | Treat the tracks as the conflict point; stop if lights, gates, flaggers, or trains require it. |
| Yellow diamond | Warning | Expect a curve, merge, intersection, narrow bridge, lane ending, slippery road, or other hazard. |
| Fluorescent yellow-green | School, school crossing, pedestrian, or bicycle area | Slow down and search for children, walkers, bicyclists, and crossing guards. |
| Yellow or orange pennant on the left | No-passing zone | Stay behind the vehicle ahead until passing is legal again. |
| White rectangle | Regulatory rule | Obey the posted instruction, such as speed, lane use, turn, or parking control. |
| Orange sign or device | Work zone or temporary traffic control | Reduce speed, obey flaggers, and expect workers, cones, lane shifts, or stopped traffic. |
| Green, blue, or brown guide signs | Direction, services, or recreation | Use them to navigate, not as warnings or traffic commands. |
Signal Rules
A green light means go only if the intersection is clear. It does not cancel right-of-way rules. If you are turning left, yield to oncoming vehicles and pedestrians. A steady yellow means the signal is changing to red, so stop if you can do so safely. A steady red means stop; a right turn on red is allowed only after a complete stop, no posted ban, and a full yield.
Use this quick signal table:
| Signal | What to do |
|---|---|
| Flashing red | Stop as you would at a stop sign; yield and proceed only when safe. |
| Flashing yellow | Slow down and continue with caution; do not treat it as a mandatory stop. |
| Green arrow | Move only in the arrow direction after yielding to anyone already in the intersection. |
| Flashing yellow arrow | Turn only after yielding to oncoming traffic, pedestrians, and bicyclists. |
| Red arrow or red light for your lane | Do not turn or proceed until a legal signal permits it. |
| Dark or malfunctioning signal | Treat the intersection as an all-way stop. |
Pavement Markings
Yellow lines separate traffic moving in opposite directions. A broken yellow line allows passing only when the way is clear. Double solid yellow lines mean no passing from either direction, although crossing for a lawful left turn into a driveway or side road may be allowed when safe.
White lines separate lanes moving in the same direction. Broken white lines permit lane changes when safe. A solid white line means stay in your lane unless an emergency or directed movement requires crossing. Stop lines show where to stop before signs or signals. Crosswalk lines mark pedestrian space, but Tennessee also recognizes unmarked crosswalks at many intersections, so drivers must still yield.
Test-Day Pattern
When a question combines controls, apply them in order: stop or yield first, then check pedestrians, bicyclists, trains, work-zone workers, and cross traffic, then decide whether the lane marking allows the movement. A broken line never makes a pass safe by itself, and a green light never gives permission to enter a blocked intersection.
You are approaching a Tennessee intersection with a flashing yellow signal, a marked crosswalk, and a fluorescent yellow-green pedestrian sign. What is the best action?
A two-lane Tennessee road has double solid yellow center lines, and you want to reach a driveway on the left. Which statement is correct?
