Dusk market street: scooter, cart and a football
Dusk in a Bamako market street. At 18:40 you are driving a light pickup at 38 km/h in a signed 50 km/h zone. Dust and cooking smoke cut visibility to about 25 m. Market stalls spill into the right lane, and a parked minibus forces you to move left of the centre line. Ahead, a donkey cart loaded with sacks moves at walking pace. Two motorcycle taxis overtake the cart toward you, one with no headlight. Children are playing beside a football on the left. Your passenger says you have priority and should keep moving. Your tyres are legal but the rear pair are worn, and the pickup is empty. You have 60 m to the next junction and no traffic officer in sight. The road surface is dry but uneven, with sand patches.
1. In the next three seconds, which hazards do you prioritise, and why?
Read the worked answer
Prioritise by time-to-collision, not by who is legally at fault.
- The two oncoming motorcycle taxis are the first threat. At 38 km/h you cover about 10.6 m per second, so 25 m of visibility is only about 2.4 seconds. One has no headlight and both are in your side of the road. A head-on impact at combined speed is the most severe outcome.
- The child and football come next. A ball rolling into the road predicts a child running after it, and children do not judge closing speed. Cover the brake now, not when the child appears.
- The donkey cart is slow and unpredictable: it may stop, turn into a stall, or shed a sack. It also hides pedestrians stepping out from the left.
- The parked minibus and stalls create a pinch point where people walk in the road.
At 38 km/h with 25 m visibility you cannot stop within the distance you can see. Reduce to about 20 km/h, cover the brake, and create space rather than claiming priority.
2. Your passenger tells you to sound the horn and hold 38 km/h to 'claim your lane'. How do you respond, and what do you actually do?
Read the worked answer
A horn is a warning device, not a right-of-way device. In a market it can startle the donkey, scatter children, and be unheard by a motorcycle taxi with no lights. Holding 38 km/h because you are legally in the right would still leave you unable to stop in 25 m, and the worn rear tyres lengthen the stop on sand.
What to do:
- Ease off the accelerator and reduce speed before reaching the cart.
- Do not swing left into the oncoming motorcycle taxis just to keep momentum. Wait until they have passed, then move out only with a clear view.
- Use the horn only if someone is already moving into your path, and accompany it with braking.
- Keep a margin from the stalls; a pedestrian can step out from between them.
- Tell the passenger plainly: 'I am not taking the gap; the motos have no lights.'
The correct judgement is to lose a few seconds rather than gamble on other people's behaviour.
3. What following distance and escape plan do you set behind the donkey cart, and how do the worn rear tyres change it?
Read the worked answer
At about 20 km/h, a normal 2-second gap is roughly 11 m. Here that is too small because the cart is slow, dust limits vision, and the driver may stop without warning. Set 3–4 seconds, about 17–22 m, and be ready to stop completely.
Escape plan:
- Primary escape is braking in a straight line behind the cart, not swerving into the stalls.
- The left side is available only if the oncoming motorcycle taxis have cleared and you can see far enough to pass. If not, stay behind.
- Identify a pedestrian-free spot on the right if the cart suddenly turns.
Worn rear tyres mean:
- Longer braking on the sand patches and a greater risk of the rear stepping out under braking.
- Less grip if you brake and steer at the same time.
So add about 50% to the gap, brake earlier and more gently, and avoid a late swerve. Empty pickups also have light rear ends, which makes skidding more likely on uneven laterite.
