Who goes first? Every Virginia right-of-way scenario, worked through.

Where state law codifies right-of-way for funeral processions, the procession may continue together through the intersection even if the signal changes after the lead vehicle enters legally. Other drivers must yield to the procession and not cut in or break the line. State coverage varies widely; many states are silent.

Pull as far to the right as is safe, stop, and remain stopped until the emergency vehicle and any others following it have passed. Do not block intersections. On divided highways, the rules for opposing-direction traffic vary by state, described in the state-specific rule below.

When exiting a driveway, alley, or private road onto a public street, you must yield to all road traffic and to any pedestrian on the sidewalk you must cross. Stop at the sidewalk, let the pedestrian pass, then look both ways before pulling onto the street.

When entering a highway, the merging vehicle yields to mainline traffic. Match the speed of the highway traffic in the acceleration lane, look for a safe gap, signal, and merge smoothly. Do not stop on the ramp unless traffic conditions absolutely require it.

When entering a roundabout, yield to all traffic already in the circle. Wait for a safe gap, then enter, drive counterclockwise, and exit at your intended street. Use your right turn signal as you approach your exit.

Yield to the pedestrian. Stop before the crosswalk and remain stopped until the pedestrian has cleared your half of the road and, in many states, until they have fully crossed. Specific stopping requirements and pass-on-the-left rules vary by state.

On a solid green light, a left turn is permitted but not protected. You must yield to all oncoming through traffic and to any pedestrians legally crossing your turn path. Only complete the turn when the way is clear.

A yield sign means you must slow down, prepare to stop if necessary, and give the right of way to all crossing or through traffic before proceeding. You only stop fully if traffic conditions require it.

At an uncontrolled T-intersection, the through road (the road at the top of the T) has the right of way. The vehicle on the terminating road yields to all traffic on the through road before turning.

Where state law codifies the rule, the vehicle traveling downhill must yield by backing up to a wider section, since reversing uphill is more difficult. Most state manuals are silent on this scenario; in those states, drivers should use courtesy and judgment.

At an uncontrolled intersection, the first vehicle to arrive has the right of way. The second vehicle yields and waits for the first to clear.

At a 2-way stop, the cross street has the right of way and does not stop. You must wait until the intersection is clear in both directions and you can proceed without forcing other drivers to slow or change course.

Yield to the cyclist before crossing the bike lane. Look over your right shoulder and check your right-side mirror, signal, and slow until you can confirm no cyclist is in or approaching your turn path. Begin the turn only when the bike lane is clear.

The first vehicle to come to a complete stop has the right of way. The second vehicle waits for the first to clear the intersection, then proceeds. Each subsequent vehicle proceeds in the order it stopped.

Every public-road intersection has an implied crosswalk, marked or not. Yield to a pedestrian crossing at the unmarked crosswalk just as you would at a marked one. State coverage of unmarked-crosswalk rules varies; some statutes only protect marked crosswalks explicitly.

At a multi-lane roundabout, yield to all traffic in both circulating lanes before entering. Choose your lane on approach based on your destination (right lane to exit at the first or second street, left lane to go further). Do not change lanes while inside the circle. Signal right before exiting.

When two vehicles arrive at an uncontrolled intersection simultaneously, the vehicle on the right has the right of way. The vehicle on the left yields.

When two vehicles arrive at a 4-way stop at the same time on perpendicular roads, the vehicle on the right has the right of way. The vehicle on the left yields and waits for the right-hand vehicle to clear the intersection.

All states require drivers to yield to pedestrians who are blind or visually impaired and identifiable by a white cane or guide dog. Stop and wait until the pedestrian has fully cleared the roadway, regardless of marked-vs-unmarked crosswalk distinctions. Many states impose elevated penalties for failure to yield in this situation.

When opposing vehicles arrive at a 4-way stop simultaneously and one intends to turn left, the through (straight) or right-turning vehicle has the right of way. The left-turning vehicle yields until oncoming traffic clears.

A green left-turn arrow gives you a protected turn. Oncoming traffic has a red signal and is required to stop. Proceed through the turn while watching for pedestrians who may still be in the crosswalk.

Treat a flashing red signal exactly as you would a stop sign: come to a complete stop, yield to all cross traffic, and proceed only when the way is clear.

A flashing yellow signal warns you to slow down and proceed with caution. You do not need to stop. Watch for cross traffic and pedestrians, especially since drivers on the cross street may have a flashing red and may be entering the intersection.

On an undivided road, all vehicles in both directions must stop and remain stopped until the bus turns off its red flashers, retracts the stop arm, and begins to move. On a divided highway, opposing-direction traffic may be exempt depending on the median configuration; the state-specific rule below describes when the exemption applies.

By default, cyclists must obey stop signs the same as motor vehicles: come to a full stop, yield to cross traffic, then proceed. Several states permit the "Idaho stop" (also called "safety stop" or "stop-as-yield"), which allows a cyclist to treat a stop sign as a yield sign when safe. The state-specific rule below describes the local treatment.

Move Over laws require you to change lanes away from the stopped vehicle when safe to do so. If you cannot change lanes, slow significantly below the posted speed limit and pass with extra caution. Specifics on which vehicles trigger the law and the required speed reduction vary by state.

After a complete stop at the red light, you may turn right unless a sign prohibits the turn. Yield to all cross traffic and pedestrians in the crosswalk before proceeding. Some states or specific intersections prohibit right-on-red by default; the state-specific rule below describes the local default.
