Pavement Markings and Signals with Signs
What this domain tests
Pavement markings and signals work with signs to control lanes, stopping, and turns. The exam tests yellow and white lines, crosswalks and stop lines, and situations where a sign changes what a signal would otherwise allow.
Core rules
- Yellow center lines separate opposing traffic. A broken yellow line allows passing when safe; a solid yellow line restricts passing on that side. Double yellow means passing is prohibited for traffic on the solid side.
- White lines separate same-direction lanes or mark the roadway edge. Dashed white lines permit lane changes when safe; solid white lines discourage or prohibit crossing as posted.
- Crosswalks and stop lines: a solid white stop line marks where to stop for a signal, stop sign, or crosswalk. Stop before the line, not on the crosswalk.
- Signals: steady red means stop; steady green means proceed if clear; a green arrow is a protected movement; a flashing yellow arrow means permitted movement after yielding; flashing red means stop, then proceed when safe.
- Sign interaction: No Turn on Red overrides the usual right-on-red permission. A Left Turn Yield on Green sign means a circular green does not protect the left turn.
Worked example
You are in a left-turn lane with a LEFT TURN YIELD ON GREEN sign. The signal is a circular green, not a green arrow. You may enter the intersection and turn left only after yielding to oncoming traffic and pedestrians. A green arrow would give a protected turn, but the sign and circular green do not.
Traps that cost marks
- Turning right on red despite a No Turn on Red sign.
- Stopping beyond the stop line or on the crosswalk.
- Treating a flashing yellow arrow as protected.
- Confusing solid and dashed lane lines.
- Assuming a circular green protects a left turn when a yield sign says otherwise.
