Passing a Cyclist on a Narrow Shoulder at Dusk
It is 20 minutes after sunset on a rural two-lane road with a posted 80 km/h limit. You are behind a cyclist riding near the right edge with a rear reflector but no visible tail light. Your lane is 3.4 m wide; the opposing lane is the same. There is a solid yellow line on your side and a dashed line on the opposing side, indicating passing is permitted for oncoming traffic but restricted for you. A vehicle is approaching in the opposite lane about 150 m away with headlights on. The cyclist is travelling roughly 20 km/h; you are at 75 km/h. There is no paved shoulder - just gravel and a ditch beyond the white edge line.
1. Can you legally and safely pass right now? Walk through the constraints.

Several constraints stack against passing at this moment. First, the solid yellow line on your side means you may not cross it to pass. Second, the oncoming vehicle at 150 m is closing fast: at a combined closing speed of roughly 75 + 75 = 150 km/h, 150 m is about 3.6 seconds of separation - far too little room to swing into the opposing lane, clear a 20 km/h cyclist, and return. Third, there is no paved shoulder, so squeezing past within your own lane would leave well under a safe lateral gap. The correct decision is not to pass. Hold back at a safe following distance and wait for a legal, clear opportunity: a dashed line on your side and no oncoming traffic.
2. What lateral clearance should you aim for when you eventually do pass, and why does the cyclist's lack of a tail light matter to your planning?

Aim to leave at least about one metre of lateral space between your vehicle and the cyclist - more at higher speeds, where a metre is a bare minimum. At 75–80 km/h, the air wake alone can destabilize a cyclist, so give a wider berth if the road allows. The missing tail light matters because it reduces how early you and the oncoming driver perceive the cyclist; at dusk a reflector is easy to miss against headlights. That argues for extra caution: pass only when you have a long, unobstructed sightline, signal your intention, and complete the pass decisively rather than lingering alongside. Never pass so close that a wobble or a pothole would put the cyclist under your wheels.
3. The oncoming vehicle passes and the road ahead is clear, but the solid yellow line continues for another 400 m before becoming dashed. What do you do?
Read the worked answer
You wait. A clear road does not override the line marking - the solid yellow on your side still prohibits crossing to pass, and the marking exists precisely because sightlines or hazards in that stretch are judged inadequate. Continue at a safe following distance behind the cyclist, reduce your speed to match the situation, and be patient until the line becomes dashed and you can confirm the opposing lane is clear for the full distance you need. If traffic behind you builds, do not let pressure push you into an illegal pass; pull over safely when you can and let faster traffic by if that reduces risk.
