Which of the following is NOT a recommended safety measure for cyclists?

The choice indicating that riding with no lights at night is not a recommended safety measure for cyclists is correct because visibility is crucial when riding after dark. Using lights improves not only the cyclist's visibility to other road users but also helps the cyclist see the road ahead clearly. Cyclists are required by law in many jurisdictions to have functioning front and rear lights at night, in addition to reflectors, to ensure they are seen by drivers and to reduce the risk of accidents.

In contrast, wearing a helmet, signaling turns, and keeping a safe distance from parked cars are important safety measures. Helmets provide essential head protection in the event of a fall or collision. Signaling turns informs other road users of the cyclist's intentions, thereby enhancing safety through better communication. Maintaining a safe distance from parked cars helps prevent accidents caused by doors opening unexpectedly or by pedestrians emerging from between parked vehicles.
