Cyclist on a Two-Lane Road with a Solid Line and a Crest Ahead
It is a clear Saturday morning in May. You are northbound at 55 mph on a two-lane county road in northern Michigan. A cyclist in a bright jersey is ahead of you, riding near the right edge at about 15 mph and weaving slightly around sand and potholes left over from the spring thaw. The center line on your side is solid yellow and stays solid for the next half mile. An oncoming pickup towing a boat is about 500 feet away and closing. Beyond the cyclist, the road rises to a crest, and just before the cyclist there is a gravel driveway and a cluster of mailboxes on your right.
1. Can you pass the cyclist right now? Walk through every factor.

No - three separate factors each rule it out on their own.
- The solid yellow line on your side means no passing. You would have to cross it to give the cyclist any margin, and the marking prohibits that here.
- The closing oncoming pickup at 500 feet is not enough room. You and the pickup are closing at roughly 110 mph combined, so 500 feet is about three seconds of clearance before the pass has even started, and the truck is towing a boat that may wander.
- The crest ahead caps your sight distance. You cannot see what is beyond the rise - a slow tractor, a stopped mail carrier, another cyclist.
Add Michigan's requirement to leave at least 3 feet of clearance when passing a cyclist, and the space simply is not there. You wait.
2. The cyclist suddenly swerves left around a pothole. What does that tell you about your following distance, and how should you adjust?

It tells you the cyclist's line is not predictable, and a following distance measured in car lengths against a fixed object is the wrong mental model.
- Cyclists must move around sand, glass, potholes, and drain grates. A swerve of a foot or two is normal and necessary riding, not erratic behavior.
- Back off. At 55 mph you need at least 3 seconds, and more is better when the rider's path is variable and the shoulder is littered.
- Watch the driveway and mailboxes. Those are cues that the cyclist may slow, signal, or turn left across your path.
- Give room in your own lane too. Do not crowd the fog line trying to 'squeeze past' - the pass has to be a real lane change, not a brush-by.
Extra space costs you seconds. A clipped cyclist costs a life.
3. The oncoming pickup passes, the center line becomes dashed, and you can see about 1,000 feet of clear road. Describe the pass correctly.

Now the pass is legal, and it should still be deliberate.
- Check and signal: mirror, signal, shoulder check for anyone behind you starting the same pass.
- Move well left - into the oncoming lane as needed - and leave at least 3 feet of clearance, more at 55 mph where a wobble or a gust can push the rider sideways.
- Do not crowd back in. Return to the right lane only when the cyclist is clearly behind you and visible in your mirror; cutting close and early is the classic cause of a right-hook or a clip.
- Complete the pass promptly rather than lingering alongside, and do not honk - a horn can startle a rider into your path.
If the dashed line had ended before you finished the maneuver, the correct move is to abort or hold back, not to finish the pass anyway.
