Gravel Road Left Turn With Cross Traffic That Does Not Stop

You are driving a three-quarter-ton pickup pulling a 24-foot stock trailer on a gravel county road in central Kansas. You approach a paved county road that carries traffic at 55 mph. Your approach has a red octagonal STOP sign and, below it, a 'CROSS TRAFFIC DOES NOT STOP' plaque. The cross road runs east-west; you want to turn left to go east. A stand of mature corn on your right limits sight distance to the west to about 300 feet; on your left you can see about a quarter mile. The gravel surface is loose and your trailer is empty but light. A grain truck is approaching from the left (west) at highway speed with its left turn signal on, and a passenger car is approaching from the right (east). You have stopped at the stop line.

1. What do the STOP sign and the 'CROSS TRAFFIC DOES NOT STOP' plaque establish about right-of-way, and why should the grain truck's left-turn signal not be treated as permission to turn?

The STOP sign controls your approach, and the plaque removes any expectation that the cross road also stops. Cross traffic has the right-of-way, so you must yield to vehicles from both directions before entering or crossing the paved road. The grain truck's signal shows intent only; it does not guarantee that the truck will turn before your intersection, that the driver has seen you, or that the signal will not be canceled. The truck may be turning into a field drive, may be slowing for a different reason, or may swing wide. You need a gap that lets your pickup and 24-foot trailer clear the eastbound lane and accelerate; a turn signal is not a clearance.

2. How should the 300-foot sight distance to the right shape your gap selection for a left turn with the trailer?

Read the worked answer

At 55 mph, traffic covers roughly 80 feet per second, so 300 feet is under four seconds of visibility. A left turn with a trailer is slow: you must cross the near lane, enter the far lane, and get the trailer completely clear before an eastbound vehicle arrives. The trailer also tracks inside the turn and slows your acceleration. You need a gap based on the worst-case vehicle that could appear from the right, not just the car you can see. If you cannot see far enough to confirm the lane is clear, edge forward until you can see, then stop again and reassess. Do not commit just because the left side is open.

3. The grain truck slows and flashes its headlights. What should you do?

Read the worked answer

Treat the flash as a possible courtesy signal, not a legal clearance. Re-check both directions, confirm the truck is actually stopping or turning before your path, and make sure the passenger car from the right is not closing. A headlight flash can mean 'I see you,' 'go ahead,' or a warning about a hazard. It does not transfer right-of-way. If there is any doubt about the truck's path or the car from the right, wait. With a trailer, a misjudged left turn is hard to abort, so the safe choice is to wait for an unambiguous gap.
