Vehicular cycling, or road cycling, is the practice of driving bicycles on roads in a manner that is visible, predictable, and in accordance with the principles for driving a vehicle in traffic. Under the international Vienna Convention on Road Traffic (1968), a bicycle (or “cycle”, as referenced by the convention) is defined to be a vehicle and a cyclist is considered to be a driver. In a minority of jurisdictions (the states of AZ, CA, IA, IL, IN, MN, NY in the USA) a bicycle is legally defined as a “device” rather than as a vehicle, but in all cases operators of bicycles share a basic set of rights and responsibilities with operators of motor vehicles. Bicyclists, who do not pose an extraordinary danger to others, are not burdened with certain additional responsibilities placed on drivers of motor vehicles — for example, only motor-vehicle operators are required to have a driver’s license and, in some localities, carry liability insurance.

Sometimes vehicular cycling is referred to as integrated cycling (i.e. integrated with other vehicular traffic, as opposed to cycling on segregated cycling facilities), integrated traffic cycling, cooperative cycling, or bicycle driving.
