Passing a Cyclist on a Two-Lane Rural Road
You are driving a sedan on a two-lane rural road with a posted 55 mph limit. It is dusk, and you have headlights on. Ahead, a cyclist is riding in your lane at about 15 mph, hugging the right edge. The road has no shoulder, a solid yellow center line, and a gentle curve about 300 feet ahead that limits your view of oncoming traffic. A line of three cars is behind you. Your speed is 50 mph. The oncoming lane appears empty in the stretch you can see, but the curve hides whatever is beyond it.
1. Can you legally and safely pass right now? Explain the decision.

No. Two independent problems block the pass:
- Sight distance. Passing requires enough clear oncoming lane to complete the maneuver and return. A curve 300 feet ahead hides oncoming traffic. At a closing speed of roughly 55 + 55 = 110 mph, 300 feet of visibility is consumed in about 2 seconds - nowhere near enough to pass, clear the cyclist, and get back.
- The center line. A solid yellow line on your side means no passing. It exists precisely because sight distance is inadequate here.
Pressure from the cars behind you does not change the rule. Slow to the cyclist's pace, hold a safe following gap, and wait for a dashed line with a long clear view before passing. Give the cyclist at least 3 feet of clearance when you do pass.
2. The cyclist wobbles slightly toward the center of the lane. How should you adjust, and what following distance is appropriate?

A wobble is a signal to create more space, not less. Back off further and prepare to stop. Cyclists may swerve to avoid road debris, grates, or potholes, and at dusk a rider may not see hazards until late.
Following distance: use at least a 3-second gap in good conditions, and extend it at dusk because depth perception and hazard detection degrade. At 50 mph you cover about 73 feet per second, so 3 seconds is roughly 220 feet - and that is a minimum, not a target.
Do not crowd or honk to push the cyclist aside. If the wobble becomes a fall, you need the gap to stop without striking the rider.
