Tailgated at Dusk with a Cyclist Ahead
At 5:45 p.m. on a two-lane road you are doing 50 km/h, and a car has been sitting about 8 metres off your rear bumper for the last two kilometres, occasionally flashing its headlights. Ahead on your side, a cyclist is riding about 60 cm from the edge line, wobbling slightly on the rough shoulder. An oncoming motorcycle is about 120 metres away. The centre line is broken. The shoulder on your right is narrow and soft. You are already late for an appointment.
1. Analyse the space you would need to pass the cyclist, and whether you have it now.

The car behind: 8 m at 50 km/h (13.9 m/s) is a 0.6-second gap. If you brake even moderately for the cyclist, the car behind arrives before it can react. That fact constrains every option that follows.
The cyclist: you want at least 1 m of clearance (more at 50 km/h), which means putting your left wheels well over the centre line - realistically most of the vehicle in the oncoming lane. The cyclist wobbling on a rough shoulder makes the clearance estimate unreliable, so add margin.
The oncoming motorcycle: 120 m, closing at roughly 50 + 50 = 100 km/h ≈ 28 m/s, gives about 4 seconds to meet. A pass that requires occupying the oncoming lane for several seconds plus the return cannot be completed in 4 seconds.
Conclusion: you do not have the space. Do not start the pass. Ease off slightly to open your own gap to the cyclist so that you can slow gradually and predictably for both hazards.
2. What do you do about the tailgater, and what must you not do?
Read the worked answer
Do:
- Hold a steady, predictable speed. Erratic speed is what causes the car behind to close and collide.
- Open a larger gap ahead of you, so any braking you do for the cyclist is gentle and early enough for the car behind to react.
- Signal your intentions early and clearly, and use brake lights early by feathering rather than stamping.
- If the car persists, put your right indicator on and pull over at a safe, wide, firm spot and let it go past. Removing a tailgater from your mirror is a legitimate defensive action.
- If the driving is genuinely aggressive (repeated close passes, horn, headlight flashing at close range), note the plate and report it - do not engage.
Do not:
- Brake-check or tap the brakes to 'teach him a lesson' - that converts his error into your collision.
- Speed up to open a gap; you raise your own speed and the closing speed if he matches you.
- Gesture, shout, or chase. Any of these escalate and none of them get you to your appointment faster.
- Let being late shorten your judgement. Lateness is a reason to leave earlier next time, not a reason to accept a smaller margin.
3. The motorcycle passes and the road ahead clears. Walk through the pass on the cyclist.

Run it as a sequence, not a single decision:
- Mirrors and shoulder - confirm the tailgater's position. If he is already moving to follow you into the gap, that changes the pass: you may need to wait so you are not three abreast.
- Signal left well before you move, so the cyclist and the car behind both know.
- Re-check the oncoming lane the moment before you commit - a motorcycle that was 120 m away can close fast, and a second one may be behind it.
- Move out and give clearance - at least a metre, ideally a full lane's width at 50 km/h, and do not accelerate hard as you go by; a revving engine close behind unsettles a wobbling cyclist.
- Return only when the cyclist is visible in your left mirror - not when you think you have cleared.
- Watch the tailgater behind you. He will very likely follow you through the same gap at too close a range to the cyclist. Leave room so that if he does something stupid, you are not part of it.
If the gap ever shrinks mid-manoeuvre, abort, brake gently and settle back behind the cyclist.
