Right-of-way at an unmarked town junction with a tram
You approach a four-way junction in a Bulgarian town. There are no priority signs and no traffic lights, so the default right-hand rule applies. Your road is paved and the cross road is also paved. A tram is approaching from your right on the cross road, running on rails set into the carriageway. A cyclist is coming from your left, close to the junction. A car behind you is following at about 1.5 seconds' gap. You intend to go straight ahead. Visibility is good and the road is dry.
1. Who has priority at this junction, and in what order should you proceed?

Because there are no signs or signals, the general right-hand rule applies: give way to traffic coming from your right. The tram comes from your right, so it has priority over you. Trams also generally have priority on their rails, and they cannot steer around you, so you must not block the rails. The cyclist comes from your left, so the cyclist must give way to you, but only if the cyclist actually does so.
The safe order is: let the tram pass first, then check that the cyclist from the left is yielding, then proceed straight ahead. Do not assume the cyclist will stop just because the rule is in your favour; be ready to wait. The car behind is not a reason to pull out early.
2. The car behind is close. How should that affect your approach, and what should you avoid?

A following gap of about 1.5 seconds is short, especially in town. If you brake suddenly for the tram, the driver behind may not stop in time. So you should slow early and progressively, using the brake gently so the brake lights warn the follower, and leave yourself room to stop without harsh braking.
Avoid stopping abruptly on the rails or in the middle of the junction. Avoid waving the follower past or accelerating into the junction to 'make the gap'. If the follower is tailgating, the correct response is to increase your own safety margin, not to speed up. You may also need to stop before the junction rather than on it, so the tram's path stays clear.
3. The cyclist from the left keeps coming. What should you do, and why does the rule not settle it?
Read the worked answer
The right-hand rule gives you priority over the cyclist, but priority is not a guarantee. If the cyclist keeps coming and does not appear to be slowing, you must give way to avoid a collision. A cyclist is unprotected and may be hard to see or may misjudge your speed, so the practical rule is to yield when the other road user is not yielding, even if the formal rule favours you.
So slow or stop, let the cyclist clear the junction, and then proceed once the tram has also passed. Do not edge forward to 'claim' your priority. The exam tests judgement, not just the rule: the rule tells you who should give way, but safety tells you what to do when the other person does not.
