Anger toward other drivers experienced while driving a car in heavy
traffic; arguments or violence between motorists
1) That lady tried to run me off the road ! She must have a bad case of road rage.
2) The police blamed road rage
for the shooting.
'Road' means 'street', and 'rage' means extreme anger, so 'road rage' is
extreme anger felt while driving a car. This term has become popular in
the last few years as more and more people spend many hours each day just
driving to work and home again.
