The cabinet on Tuesday approved a higher speed limit of up to 120 kilometres per hour on national and rural highways.
The rule applies to highways with at least two lanes running in the same direction and traffic islands with barriers.
The new speed limits are expected to improve traffic flow.
The speed limit for trucks weighing over 2,200kg and buses with more than 15 passengers is 90km/h, while buses with 7-15 passengers are allowed to go up to 100km/h.
Smaller motorcycles won't be allowed to exceed 80km/h, while those with 400cc engines and above are limited to 100km/h.
School buses must not exceed a speed limit of 80km/h.
The speed limit for vehicles travelling in the furthest right lane is no less than 100km/h.
