Dead lights, a waving officer and a wet junction at Naivasha
21:40 on the old Naivasha–Nakuru road. Rain has fallen for an hour and the tarmac is glossy. You are driving a 1,400 cc saloon with your family aboard, approaching a four-leg junction where the traffic signals are completely dark after a power cut. A police officer in a reflective jacket stands in the middle of the junction with a torch, waving traffic from the left arm straight through. On your approach the 'Give Way' sign has been knocked flat by a lorry and lies face-up on the verge, and the stop line and lane markings are worn to a faint grey. Two hundred metres before the junction a lorry is parked half on the shoulder with its rear lights off and no warning triangle behind it. A matatu is following you closely, engine revving, headlights on main beam and filling your mirrors. A pedestrian in dark clothing is walking along the nearside edge of your lane.
1. The lights are dead, the sign is down and the markings are worn. Which instruction actually governs your movement here, and how do you rank the sources of authority you can see?
Read the worked answer
The hierarchy of authority, highest first, is: a police officer directing traffic → traffic signals → road signs → road markings → the general rules of the Highway Code.
The reasoning is about who can respond to the situation. Signals and signs are fixed devices that cannot see the queue, the flood, the power cut or the lorry on the shoulder. An officer on the ground can. So where an officer is actively controlling a junction, his signal overrides everything else present - even, if the two conflicted, a green light.
Applying that here:
- The signals are dark, so they say nothing at all. A dead signal is not a green light.
- The Give Way sign is lying on the verge. It has not been repealed: you know it was there and you know what it meant, so approach on the basis that you must give way.
- The worn stop line and faded markings do not cancel the obligation either. Worn paint is a maintenance problem, not a permission.
One important limit: the officer's wave is permission, not a guarantee. It does not transfer your duty to look. You still proceed only when you can see the way is clear, because the officer may not have seen the pedestrian on your nearside or a vehicle cutting the corner.
2. Describe step by step how you would take the car through this junction, from about 150 m out to 50 m past it. Include speed, gear, position, observation and how you handle the matatu behind you.

150–80 m out: Ease off the accelerator early and brake gently and early rather than late and hard. The matatu is close, so give it plenty of time to see you slowing. Keep the car in a straight line while braking on the wet surface. Target about 20–25 km/h by the junction - second gear, clutch down and ready to slip if you need to creep.
Position: Keep slightly left of the centre of your lane, but do not drift onto the edge. You want clearance from the pedestrian on the nearside and room to move left if something cuts the corner.
Observation: Mirror, then right–left–right again. Look specifically for vehicles ignoring the officer. The parked lorry's shadow hides anything that might pull out. Do not stare into the matatu's main beam - look at the nearside edge line and use peripheral vision.
Commit: Make eye contact with the officer; move only when he signals you and the way is visibly clear. Cross the junction steadily in a low gear. Do not stop dead in the middle and do not hesitate halfway across.
The matatu: If it swings out and overtakes you into the junction, yield. Being legally right is worth nothing against a collision. If it continues to tailgate, do not brake-check; a long, gentle brake application is your only message.
The pedestrian: Cover the brake until you are well past, and be ready to stop rather than swerve on a wet surface.
3. Suppose the officer had gone off duty and the lights were still dead. What governs your movement then, and what would you do differently?
Read the worked answer
With no officer present, authority drops back down the hierarchy to the Give Way sign and markings - and to the default rule for an uncontrolled junction, since the sign is physically down but you know it applies.
What that means in practice:
- Treat the junction as a give-way junction. In left-hand traffic you give way to traffic approaching from your right, and to anyone already committed in the junction.
- The worn markings and flattened sign do not lower the standard. If anything they raise it, because other drivers may not see them either.
- Approach at a speed from which you can stop within the distance you can see to be clear. In rain, at night, with a dark-clothed pedestrian on the nearside and a parked lorry blocking the view, that speed is walking pace, not 40 km/h.
What changes:
- You lose the officer's early warning function, so you must announce yourself: a brief flash of headlights on the approach and a short horn warning where it is needed.
- You must build in a second look because nobody is managing conflicting flows.
- You should expect another driver to treat the dead lights as a free-for-all and drive straight through. Assume the worst and wait until you have seen the road is clear, not until you have failed to see anything coming.
