theres a misconception in pakistan tht on highways, u hav to keep your right turn signal on while u r driving on the fast lane, specially in case of 2-laned highways like super highway. ppl r afraid tht if they dont follow this, motorway police will come into action. i have a friend working in motorway police and according to him, this is absolutely wrong. you shud engage ur turn signals only while changing lanes in either direction, and shud turn these off as soon as u hav changed the lane completely.
taking advantage of this opportunity, i wud request all highway goers to pls dont use turn signals unnecessarily as sometimes it sends a very wrong signal to the driver coming from the rear and may cause fatal accidents. in short....
DONT KEEP YOUR RIGHT INDICATOR ON WHILE YOU ARE CONTINUOSLY DRIVING ON THE RIGHT LANE!!!
