Night Breakdown on a Shoulder with a Partly Loaded Trailer
At 23:20 on an unlit two-lane road outside a town, your Category C truck loses electrical power and coasts to a stop. You manage to pull the cab mostly onto the shoulder, but the trailer's left rear corner remains about 0.8 m inside the right-hand traffic lane. Visibility is poor, the road is wet, and traffic passes at about 80 km/h. Your hazard lights work from the battery, but the engine will not restart. You have a warning triangle, a high-visibility vest, and a phone with weak signal. The nearest settlement is 4 km back.
1. List your actions in order for the first five minutes, and justify the order.

Order matters because each step reduces the chance of the next being fatal:
- Put on the high-visibility vest before opening the door, so you are visible the moment you step out.
- Switch on hazard lights and, if fitted, side and rear marker lights.
- Exit on the side away from traffic, never into the live lane.
- Place the warning triangle behind the vehicle on the shoulder at the distance required for an obstruction on this road, walking back facing traffic and returning the same way; if the shoulder is too narrow to walk safely, do not attempt it and rely on lights and a call for help.
- Call emergency services and your dispatcher, giving the road, direction, nearest kilometre marker and the fact that the trailer protrudes into the lane.
- Move well off the carriageway, behind the barrier if there is one, and stay there.
Do not stand between the cab and trailer or behind the vehicle to wave traffic.
2. The trailer still blocks 0.8 m of the lane. What additional warning is justified, and what is not?

Justified: hazard lights plus any reflective markers you have placed on the protruding corner; a triangle set back on the shoulder; and a call that explicitly tells the operator the lane is partially blocked so that police or road services can place cones or direct traffic. If you have a torch, use it to signal from a safe position off the carriageway, not from the lane.
Not justified: standing in the lane waving a torch at 80 km/h traffic, placing branches or stones in the lane, or leaving the scene to walk 4 km for help in the dark while the obstruction is unmarked. Each of those creates a new hazard. Your job is to make the obstruction visible and get professional help, not to personally direct traffic on an unlit road.
3. A passing driver stops and offers to tow you 4 km to the settlement. How do you answer?
Read the worked answer
Decline for the road itself. A rope tow of a loaded Category C combination at night on a wet unlit road, with a trailer and no brake or light connection, is far more dangerous than waiting. The towed vehicle has no working brake lights or indicators linked to the tower, the combination length makes signalling impossible, and the trailer would track unpredictably.
Accept only what is safe: the driver can call the emergency services from a stronger signal area, or lend a torch. If recovery is needed, it should be a proper recovery vehicle with a rigid connection and lighting. Record the passer-by's offer and your refusal in your notes, since it shows you weighed the option.
