The government has decided to fix the speed limit of vehicles on highways across the country at 80 kilometers per hour in a bid to reduce frequent road accidents.

"We will issue a circular in a few days mentioning the date when the decision will take effect," Road Transport and Bridges Minister Obaidul Quader said today after a meeting on the National Road Safety. 

There will be a "speed governor seal", a speed measurement device, installed in all highway buses and the speed limit will be fixed by the authorities to reduce the growing number of traffic mishaps caused largely by speedy driving, the minister told the meeting this afternoon.

About the speed governor seal, Quader said speed governor seal mechanism is used for controlling the speed limit of motor vehicles as per the officially approved speed limit fixed by the authorities concerned.

Whenever a driver tries to go beyond the approved speed limit, the mechanism restricts acceleration by adjusting engine fuel injection system, he added.

About the ban on three-wheeler, he said there will be no compromise with the ban on auto-rickshaws on highways.
