Passing a Cyclist on a Narrow Rural Road
You are on a two-lane rural road east of Edmonton, posted 80 km/h, with no shoulder and a solid yellow centre line. A cyclist is ahead in your lane doing about 25 km/h. You are doing 80 km/h. Oncoming traffic is light but a car is visible about 250 m ahead coming toward you. The road curves gently to the right beyond the cyclist. There is a shallow ditch on your right. It is mid-afternoon with good visibility.
1. Can you pass the cyclist now? Walk through the decision.

No - not at this moment. Reasons:
- Solid yellow line: in Alberta you may not cross a solid yellow centre line to pass. That alone prohibits the manoeuvre here.
- Oncoming vehicle at 250 m: closing speed is high (80 + ~80 = ~160 km/h ≈ 44 m/s), so you'd meet it in about 5–6 seconds. A pass at 80 vs 25 km/h takes several seconds just to get alongside and clear - not enough margin.
- Curve ahead: the gentle right curve limits how far you can see and whether the oncoming driver can see you.
- No shoulder: you cannot give the cyclist the safe lateral clearance (about 1 m minimum, more at higher speed) without moving into the oncoming lane.
Correct action: slow to the cyclist's pace or below, hold a safe following gap, and wait until the oncoming car passes, the line permits, and you have clear sightlines through the curve. Passing is a decision to make only when every one of those conditions is met.
2. The oncoming car passes and the line becomes broken. What must you verify before and during the pass, and what clearance should you give?

Before:
- Confirm the centre line is now broken on your side and you can legally cross it.
- Look well beyond the cyclist through the curve - you need enough clear sightline to complete the pass and return to your lane, not just enough to start it.
- Check mirrors and blind spot for anyone overtaking you.
During:
- Signal, move well into the oncoming lane, and accelerate decisively - don't dawdle alongside.
- Give the cyclist at least 1 m of lateral clearance (more is better at 80 km/h, since air turbulence and wobble risk rise with speed). Do not squeeze back in early.
- Return to your lane only when you can see the cyclist in your mirror.
Judgement point: if a new oncoming vehicle appears mid-pass, complete the pass rather than braking back alongside the cyclist - aborting into the cyclist's space is more dangerous than finishing. The clearance and the sightline are the two things you must not compromise.
