The Four-Way Stop With a Stalled Lead Car

You are eastbound on a two-lane city street approaching a four-way stop. Three other vehicles are already there: a northbound car that arrived first and is stopped, a southbound pickup that arrived second, and a westbound SUV that arrived at the same moment you did. As the northbound car begins to move, its engine dies and it stalls in the middle of the intersection, blocking the east-west lane. The driver restarts it twice without success and waves apologetically. A pedestrian is now waiting at the corner to your right, and the southbound pickup is edging forward. Traffic behind you is beginning to stack up.

1. Who has the right-of-way as the vehicles sort themselves out, and what should you do first?

First, do nothing aggressive. A four-way stop is resolved by arrival order, and the northbound car arrived first - but a stalled vehicle blocking the box changes the practical picture. The northbound car cannot proceed, so it is no longer 'using' the right-of-way it was granted.

Order of operations:

  1. Confirm the northbound driver is safe and not rolling; give them a moment to restart or wave others through.
  2. Once it's clear they're stuck, the southbound pickup (second to arrive) may proceed straight or turn, provided the intersection is clear.
  3. You and the westbound SUV arrived simultaneously. When two vehicles reach a four-way stop at the same time and are not in each other's path, both may go. If your paths cross (e.g., you're both going straight toward each other), the vehicle on the right yields - that's the westbound SUV if you're facing each other head-on and turning across its path.

The pedestrian overrides all of this. A pedestrian waiting at a marked or unmarked crosswalk at your corner has the right-of-way the moment they step off the curb. Do not roll through to 'claim your turn' while they're waiting.

2. The stalled car is blocking your lane and you cannot safely go around it without crossing the center line. What is the correct move?

You may cross the center line to pass a stationary obstruction only if it is safe and legal - solid yellow means no passing, so you'd need a broken line or a clear, unobstructed view with no oncoming traffic. In a four-way stop with stacked traffic, the safer answer is usually to wait until the stalled car is moved or the driver waves you through, then proceed slowly with your signal on.

Do not treat the stop sign as satisfied by creeping around the obstacle - you still owe a full stop and a clear intersection before entering. If the blockage persists, the practical move is to back off, allow the southbound and westbound traffic to clear, and take your turn when the box is genuinely open. Honking or squeezing past a pedestrian corner is the wrong call.
