Left Turn at an Uncontrolled Gravel T-Intersection with a Combine and a Closing Cyclist
At 4:15 p.m. on a clear October day you are northbound on a gravel county road at about 35 mph, approaching a T-intersection with a paved east-west road. No stop signs, yield signs, or pavement markings control the intersection. You want to turn left onto the paved road. A 30-foot combine with its corn header attached is westbound on the paved road at roughly 15 mph, planning to continue straight past the intersection. A road cyclist is 40 feet behind you, descending fast at about 20 mph and closing. Dust from the combine hangs in the air, and a crest about 350 feet to your east limits how far you can see vehicles coming from that direction. Your windshield is dusty, the sun is low in the west, and your right rear tire is a little soft.
1. Who must yield, and how should you set up the turn given the gravel surface and the size of the combine?
Read the worked answer
Your left turn crosses oncoming traffic, so you must yield to the combine. The uncontrolled-intersection rule about yielding to the vehicle on your right does not apply here, because the combine is approaching from the opposite direction and going straight - the left-turn rule controls.
Setting up the turn:
- Brake early and gently. Gravel offers far less grip than pavement, so a hard stop from 35 mph can slide you straight into the paved road.
- Signal before you brake, not while you brake, so the cyclist behind you and the combine operator both see your intention early.
- Position close to the centerline but leave extra clearance. A 30-foot header can overhang the center by several feet, and the operator's view directly in front and to the right is poor.
- Keep your front wheels straight while you wait. If you are rear-ended with the wheels already turned left, you get pushed into the oncoming lane.
- Turn only after the combine has fully cleared and you have re-checked the east approach. At 350 feet, a truck doing 60 mph is only about four seconds away - the crest is much closer in time than it looks.
2. How does the cyclist descending behind you change your plan, and what is the specific collision you are trying to avoid?
Read the worked answer
The hazard is a cyclist overtaking on your left at 20 mph just as you swing left across that same space. Closing 40 feet at a 15 mph speed difference takes only a couple of seconds.
What to do:
- Check the mirror before you brake, and brake gently and early. A panic stop on gravel can put the cyclist into your rear bumper or send you sideways.
- Signal your left turn well ahead so the cyclist knows you are turning, not just slowing.
- If the cyclist is committed to passing, let them go. Hold your position with the wheels straight and wait until they have cleared the intersection before turning. Turning across a passing cyclist is a classic right-of-way crash, and on a loose surface you cannot count on stopping or swerving cleanly.
- Do not wave the cyclist through. Predictable signals beat friendly gestures; the cyclist has to make their own judgment about your speed, the combine, and the road surface.
The combine also matters here: if the cyclist passes you, they may then meet the combine's header overhang near the centerline, which is another reason to be patient rather than to hurry the turn.
3. The combine operator slows and waves you across. Do you go? Explain your reasoning.
Read the worked answer
No. A wave means only that the operator does not intend to move right now; it does not clear the road for you.
Why the wave is unreliable:
- The operator sits high and far back, with a header blocking the view low and to the right. There is a large area of the intersection the operator simply cannot see.
- The combine might be about to swing wide, and the header overhang can sweep into your path even if the tractor itself stays put.
- Traffic from the east beyond the 350-foot crest is invisible to both of you. The operator cannot warn you about a truck neither of you can see.
- A third vehicle - the cyclist, another farmer, a grain truck - may be entering from a direction the operator is not watching.
- If you pull out and get hit, 'the driver waved me through' is not a legal defense. The left-turning driver still owns the yield.
Acknowledge the gesture, keep your wheels straight, and move only when you can personally see that the intersection and the east approach are clear.
