Overtaking a tractor on a country road before a hidden dip
You are on a two-lane country road outside the built-up area, dry weather, daylight. The speed limit is 90 km/h. Ahead a tractor is doing 25 km/h, and you have been behind it for 2 km. The road has a dashed centre line that becomes a continuous line about 150 m ahead, where the road dips and curves right. You can see about 200 m of clear road ahead before the dip, but not beyond it. A car is visible in your mirror about 300 m back, closing at maybe 100 km/h. Your car accelerates from 25 to 90 km/h in about 12 seconds.
1. Is it safe and legal to overtake here? Work through the distances.

No. Two things rule it out. First, the continuous line begins 150 m ahead: crossing or straddling a continuous line is prohibited, so any overtake must be finished before it, and you cannot guarantee that. Second, and more fundamental, you cannot see beyond the dip. An overtake requires a clear view of oncoming traffic for the whole manoeuvre; a hidden dip means an oncoming car could appear with no warning.
Do the arithmetic: at a closing speed of about 65 km/h (90 minus 25) you need roughly 4-5 seconds just to pass, plus acceleration time, covering well over 100 m, and you would be committed right at the point where visibility ends and the line becomes solid. The closing car behind adds pressure but does not create a gap. The correct choice is to stay behind, keep a safe following distance, and wait for a straight section with a broken line and full visibility.
2. The driver behind is now tailgating and flashing. How do you handle the pressure without taking the risk?

Recognise the pressure for what it is: the other driver wants you to make the overtake for them. Your job is to stay predictable and legal. Keep a steady position behind the tractor with a proper two-second gap, do not brake-check, and do not speed up and slow down erratically. If the road allows, move slightly right to give the follower a view, which often reduces frustration.
If the tailgating persists, the safest option may be to pull over at a safe lay-by or junction and let the car pass, removing the pressure entirely. Do not let another driver's impatience push you into a manoeuvre you would not choose yourself; the legal and physical consequences land on you, not on them.
