CENTER TURN LANE: The center lane is used for left turns in both directions. Traveling or passing across the center turn lane is prohibited.
YIELD: Slow down and give vehicles crossing your route the right of way. If the path is clear, you may proceed slowly without stopping. Yield signs are typically installed when auxiliary roads connect to major roadways.
Diamond-shaped signs are allocated for warning and construction zones. However, road construction signs are orange and black, whereas warning signs are yellow (occasionally bright green) and black.
SCHOOL AHEAD: School signs take the shape of a pentagon. This five-sided sign indicates that you are near a school. Keep an eye out for children.
RAILROAD CROSSING AHEAD: The advance warning sign is typically the first sign you encounter when approaching a highway-rail crossing. The advance warning sign tells you to slow down, look and listen for trains, and prepare to stop if one approaches.
Some cars are not intended to keep up with traffic. Farm tractors, animal-drawn carts, and road maintenance vehicles often go at 25 mph or less. Slow-moving cars feature an orange or red triangle on the back.
The railroad crossbuck sign is put at railroad crossings where the rails intersect the road. The crossbuck sign can be treated similarly to a YIELD sign: slow down,
listen for trains, and prepare to stop if you see or hear one approaching.
The WRONG WAY sign may or may not be displayed beside the DO NOT ENTER sign. If you notice one or both of these signs, pull to the side of the road and stop. You're driving against traffic. When you're safe, back out or turn around and head back down the road. If you are driving the wrong way at night, the road reflectors will illuminate your headlights in red.
A white stop line or two parallel lines may be painted across the road at a junction controlled by a STOP sign, YIELD sign, or traffic light. This is a pedestrian crossing. When you are compelled to stop due to a sign or light, you must do so before reaching the stop line, if one exists, or the crosswalk. You must only stop at a stop line or crosswalk if required by a light, sign, or traffic officer, or yield to a pedestrian, in-line skater, or scooter at a designated or unmarked crosswalk.
Orange construction signs indicate that you are approaching a work zone on the expressway. The route may be small, traffic may be controlled by a flagger, and workers and machinery may be present on or near the freeway. Be prepared to face all of these problems and avoid speeding. Maintain a safe gap between yourself and the car in front of you to avoid a rear-end collision.
The DO NOT ENTER sign is typically put at the start of one-way streets and ramps, and it bans automobiles from entering a one-way route where traffic is traveling in the other direction. A DO NOT ENTER traffic sign is typically erected in conjunction with the "WRONG WAY" sign.
