Understanding Right of Way at a Four-Way Stop
Confusion over right of way at a four-way stop causes may results in collisions and legal disputes. Missouri drivers must follow basic rules of the road to stay safe.
The Rules: Who Goes First?
Missouri incorporates widely accepted right-of-way rules—designed to clarify which driver proceeds first.
First to Stop, First to Go
The rule is straightforward: the first vehicle to come to a complete stop at the intersection may proceed first.
Yield to the Right
When two vehicles stop at the same time, yield to the driver on your right.
Straight vs. Turning
If you arrive simultaneously with another driver and one of you is turning left, yield to the one going straight.
If neither of the above rules applies, straight traffic receives priority.
Full Stop Required
Every vehicle must make a complete stop behind the stop line before entering.
Bobby Thrasher, shareholder at Monsees & Mayer, explains: “Rolling through a four‑way stop isn’t just careless—it is legally equivalent to missing your turn. Missouri law requires complete stops to establish right of way.”
When Everyone Arrives Together
If three or four vehicles arrive at exactly the same moment, follow the clockwise yield pattern: yield to the driver on your right.
“If more than one vehicle arrives at the same time, the vehicle on the right goes first.”— U.S. Department of Transportation, National Highway Traffic Safety Administration – Right-Of-Way Rules
In practical terms, drivers may rely on signals or gestures to manage the flow safely.
Frequent Errors That Cause Crashes
Many accidents at four-way stops stem from these common mistakes:
- Rolling instead of stopping
- Incorrectly assuming someone else will yield
- Forgetting to yield when turning left
- Not signaling intentions
- Misjudging arrival order
Bobby Thrasher notes: “We often handle cases where both drivers believe they had the right of way. Once discovery in a lawsuit unfolds, the evidence generally tends to reveal the truth, including photos, videos, witness statements, electronic data, and expert witness testimony.”
Determining Fault in a Four-Way Stop Crash
In Missouri, the at-fault driver in such accidents is typically the one who violated right-of-way rules. Law enforcement and investigators will look at:
- Who stopped first and whether it was a full stop
- Evidence such as skid marks or damage patterns
- Police and witness statements
- Any citations issued
Missouri’s Comparative Fault System
Missouri applies rules of pure comparative fault, which allows the injured party to recover damages reduced by their own percentage of fault. For example, 30 percent fault attributed to the injured party yields 70 percent recovery of the damage amount awarded by the jury.
Bobby Thrasher adds: “Comparative fault reflects reality: you might share some blame, but that doesn’t eliminate your right to fair and reasonable compensation under Missouri law.”
What to Do After a Collision at a Four-Way Stop
Solid documentation following an accident strengthens your position:
- Get medical attention
- If able, call the police
- Take photograph of vehicles, signage, and injuries
- Collect contact information from other parties and witnesses
- Avoid discussions concerning fault
- Keep records of all related medical and repair expenses
Staying Safe at Four-Way Stops
Following the rules of the road is a simple way to prevent confusion and accidents:
- Always come to a complete stop
- Use your turn signal consistently
- Make brief eye contact with other drivers
- Yield when uncertain—follow the legal sequence
- Treat other drivers courteously, not competitively
Bobby Thrasher concludes: “Following the rules of the road enables safer, smoother traffic flow. But drivers must apply them consistently—or they invite risk and liability.”
