Overtaking the Tractor Before the Crest
You are on a single-carriageway rural road with one lane each way, a solid white line on your side and a broken line on the other, and a gentle crest about 150 metres ahead. You are doing 60 km/h behind a slow tractor doing about 20 km/h, and have been for two kilometres. The road behind is clear. Ahead, beyond the tractor, you can see perhaps 80 metres of clear road before the crest hides everything. A side track joins from the left just before the crest. Your vehicle is a small hatchback with four adults aboard, and acceleration from 60 km/h is modest when fully loaded.
1. Assess whether an overtake is safe here, using the sight-line and the road markings.

No. The controlling fact is the sight-line: I can see only about 80 metres beyond the tractor before the crest, and an overtake needs enough clear road to accelerate past, return to my lane and still have a margin. A loaded hatchback at 60 km/h pulling out to pass a 20 km/h tractor needs a considerable distance to build the speed difference, complete the pass and pull back in - far more than 80 metres. The crest hides oncoming traffic, so I cannot know the road is clear.
The markings reinforce this: a solid white line on my side means overtaking is prohibited, and it is normally placed where visibility is inadequate. The side track before the crest adds a further hazard, since a vehicle could emerge or turn into it. The correct decision is to stay behind the tractor, keep a safe gap, and wait for a broken line with a long clear view.
2. What would you need to see before starting an overtake, and how would you carry it out?
Read the worked answer
I would need: a broken line on my side; a clear view well past the crest or bend, long enough that no oncoming vehicle could arrive during the whole manoeuvre; no junction or side track into which someone might turn; and enough performance in the vehicle to complete the pass briskly. With four adults aboard I should plan a longer gap, not a shorter one.
Execution: check mirrors and blind spot, signal, move out only when the view is confirmed clear, and accelerate decisively in the correct gear so the pass is quick. Keep a lateral gap from the tractor and from any oncoming traffic, pass only when I can see the tractor's front wheels and road ahead, then signal and return to my lane only when the overtaken vehicle is visible in the interior mirror. If anything changes - a vehicle appears at the crest, the tractor drifts - I abort by braking and dropping back, not by forcing the pass.
3. The driver behind you starts edging out to overtake you and the tractor together. What do you do?
Read the worked answer
I must not treat this as a race. My job is to keep the situation predictable and leave the other driver room to abort. I hold my speed steady rather than accelerating, keep well back from the tractor so there is space for an aborted pass to slot back in, and do not move left or squeeze the overtaking vehicle. If the driver is committed and oncoming traffic appears, I ease off and, if safe, move slightly toward the left edge of my lane to widen the gap, but I do not brake sharply or swerve.
I would also avoid any signal or gesture that could be read as inviting the pass. Once the vehicle is back in lane, I resume a safe following distance. The underlying principle is that I cannot control the other driver's judgement, only reduce the consequences if it fails.
