Road rage
Road rage (also road violence) is the informal name for deliberately dangerous and/or violent behaviour under the influence of heightened, violent emotion such as anger and frustration, involving an automobile in use.
This can involve deliberately hitting another person, vehicle or object with his/her own vehicle and/or firing a weapon from it. Other possibilities include hitting the person or vehicle with an item which is not his vehicle (e.g. using a golf stick), but which ultimately hits another person or vehicle.
Getting out of one's vehicle to another person's vehicle and banging, knocking on the windows, and yelling insults, is another form of road rage.
To avoid road rage, drivers are encouraged to lock all doors when driving in thick traffic at slow speeds. Those who inflict road rage often occur in such traffic situations. To avoid not being able to get out on expressways, however, doors should be unlocked on expressways.
Road rage is a relatively serious act; it may be seen as a violation of property rights and an endangerment of personal security.
