Road protests in the United Kingdom usually occur as a reaction to a stated intention by the relevant authorities to build a new road, or to modify an existing road. Reasons for opposition to opening new roads include a desire to reduce air pollution and thus not wishing to incentivise increased or sustained car usage, and/or a desire to reduce or maintain low noise pollution by not having or increasing the use of motor vehicles in the area of the planned/proposed road. Protests may also be made by those wishing to see new roads built, changes made to existing roads, or against restricting their use by motor traffic.
