Harmattan Dust and a Cracked Helmet
At 05:20 during harmattan, you plan a 12 km ride on a 100cc motorcycle to a market. Visibility is about 80 m because of dust; temperature is 18°C. Your only helmet has a cracked visor that fogs quickly, and you wear prescription glasses. You have a fever and took a cough syrup containing chlorpheniramine 30 minutes ago. Your passenger has no helmet and wants to sit sideways because her wrapper is long. You plan to wear sandals, a thin jacket, and no gloves. The route includes two checkpoints and a rough unpaved section. You feel shivery but say you can manage. Decide whether to make the trip, and identify the helmet, fitness, clothing, and passenger issues that must be resolved before any riding.
1. Should you make the trip? Give your reasoning.

You should not make the trip. A fever and shivering already reduce concentration and reaction time, and chlorpheniramine is a sedating antihistamine that can make you drowsy even if you feel alert. Harmattan dust cutting visibility to 80 m adds a further hazard, and the route includes checkpoints and rough road. The absence of a passenger helmet is a separate blocking issue: no helmet, no passenger. You also have no gloves, thin clothing and sandals, which offer little protection if you fall. The correct decision is to postpone, arrange another rider, or use public transport. If the trip is essential, wait until the sedative effect has worn off and the fever has settled, and do not ride until both you and the passenger have serviceable helmets. Feeling able to manage is not the same as being fit to ride.
2. What is wrong with the helmet and eyewear plan, and what would you require instead?
Read the worked answer
The cracked visor is not a cosmetic problem. It can shatter or distort vision, and fogging on a cold harmattan morning will make it worse; you cannot keep wiping a cracked visor while riding. Wearing prescription glasses under a helmet is acceptable only if the helmet fits without pressing the frames and the visor is clear. A serviceable helmet with a clean visor, or well-fitting goggles, is required. If the only helmet fogs, treat that as a reason not to ride in low visibility. Do not ride with the visor up at 60 km/h to see better; dust and insects can injure your eyes. The test is practical: if you cannot see clearly through the visor before you start, you will not see clearly at a checkpoint or on the rough section.
3. How should the passenger sit and dress, and why does it matter on this route?
Read the worked answer
A passenger sitting sideways is unsafe because she cannot brace against acceleration or braking and can slide off in a bend. Her long wrapper can catch in the chain, wheel or footrest. She must sit astride, facing forward, with both feet on proper footrests and her hands holding the grab rail or your waist. She needs a helmet that fits and is fastened. The long wrapper should be tied or tucked so it cannot trail. Because the bike is only 100cc and the route is rough, keep speed low and avoid sudden movements. If she refuses the astride position or helmet, the ride does not happen. This is not a style preference; it is the difference between a passenger who can stay with the bike and one who becomes a casualty.
