systems, or as a means of avoiding or reducing the effects of urban congestion.[45] In places where it is permitted, lane splitting, also known as filtering, allows motorcycles to use the space between vehicles to move through stationary or slow traffic.[46]
In the UK, motorcycles are exempt from the £8 per day London congestion charge other vehicles must pay to enter the city during the day. Motorcycles are also exempt from toll charges at some river crossings, such as the Severn Bridge, Dartford Crossing, and Mersey Tunnels. Some cities, such as Bristol, allow motorcycles to use bus lanes and provide dedicated free parking. In the United States, those states that have high-occupancy vehicle lanes also allow for motorcycle travel in them. Other countries have similar policies.
In New Zealand motorcycle riders are not required to pay for parking that is controlled by a barrier arm;[47] the arm does not occupy the entire width of the lane, and the motorcyclist simply rides around it.[48] Many car parks controlled in this way supply special areas for motorcycles to park, so as not to unnecessarily consume spaces.
In many cities that have serious parking challenges for cars, such as San Francisco, motorcycles are generally permitted to park on the sidewalk, rather than occupy a space on the street which might otherwise be used by a car.[citation needed]
