Yes, cyclists, like drivers, are breathalyzed. According to the law, any vehicle, including bicycles, must have a working headlight at all times when operating on a public road. When pulled over by a peace officer, cyclists must identify themselves and show their driver's license, registration, and proof of insurance. If the officer has reasonable grounds to suspect that the cyclist has been riding a bike while under the influence of alcohol, the officer may request that the cyclist submits to a breathalyzer test.
