Overtaking on the Climb to the Crest
It is 07:45 in early spring on the two-lane road that climbs from Rabat towards Dingli. The limit is 80 km/h. You are doing about 38 km/h behind a tractor towing a heavily loaded hay trailer that sways each time it crosses a repair patch. The centre line is continuous for the next 200 metres, then becomes broken. The road rises to a crest about 120 metres ahead, and a narrow side road joins from the right just before the crest. The sun is low and directly ahead of you, and yesterday's rain has left wet patches; loose limestone gravel has been washed onto the edges. A motorcyclist has just overtaken you and is now sitting roughly two seconds behind the tractor. The car behind you is close enough that you cannot see its headlights in your mirror.

Case against, factor by factor.
- Continuous centre line: crossing it is prohibited, and the broken section is 200 metres away.
- Crest 120 metres ahead: you need to see oncoming traffic for the whole manoeuvre and be certain none can appear; you cannot.
- Side road on the right before the crest: a vehicle can emerge straight across your path while you are alongside the trailer.
- Low sun: oncoming cars are silhouettes, and the tractor driver's mirrors are useless in the glare, so he may not see you either.
- Wet patches and washed gravel: less grip for accelerating and steering, and much longer braking if you have to abort.
- The swaying trailer: the tractor's line is unpredictable, and a swerve while you are next to it leaves no margin.
Case for. Only the speed difference - a few seconds gained.
Conclusion. No. You would go only with a broken line, a clear view well beyond the crest, the junction behind you, a dry surface, no oncoming traffic, and an escape route you could take if the tractor moved over.
2. The motorcyclist pulls out to overtake the tractor just before the crest. What do you do?

Protect his escape route. Your job is to keep the space he can drop back into, not to join the move.
- Drop back from the tractor to open a gap big enough for the rider to return into if he aborts. If you close up behind the trailer, his only options become the oncoming lane or the back of the tractor.
- Cover the brake and watch the crest and the side road rather than the bike, since that is where the danger will come from.
- Do not follow him out. Two overtaking vehicles cannot abort into the same piece of road.
- Do not flash the tractor or wave the rider on. You cannot see what he sees, and any signal will be read as an invitation to commit.
- Look for a car emerging from the side road: if one appears, the rider's options collapse and you should be slowing already so there is somewhere for him to go.
When he completes the move, rebuild your two-second gap behind the trailer. If he pulls back in, accept the delay without a gesture; he has just demonstrated why the road is not ready for overtaking.
3. What following distance would you keep, and how do your speed and spacing decisions change in the wet, in low sun, and with a tailgater behind?
Read the worked answer
Baseline. On a dry road, at least two seconds behind the trailer - pick a marker and count. In the wet, low sun, and with gravel on the edges, double it to four seconds or more. These conditions lengthen your braking distance and shorten the distance at which you can recognise a hazard, so the gap has to cover both.
Behind a swaying load. Add a further margin. The trailer's brake lights may be partly obscured by the hay, and its line is unpredictable, so you want time to react to a swerve rather than to a signal.
With a tailgater. Do not brake-check him and do not speed up beyond what the road allows; both escalate the risk. Instead, increase the gap in front of you, so that any slowing can be done gradually rather than as a sharp brake that leaves him no time. If you can, pull into a lay-by or a wide verge and let him pass. Your own 80 km/h limit is irrelevant here: at 38 km/h the danger is not speed, it is the space you do not have.
