Expressways

Most expressways are multi-lane (3 or more) carriageway with shoulders and carry traffic at a higher speed. Therefore, drivers need to be more alert in order to cope with any road hazards.

Expressways

Most expressways are under the Route Numbering System with associated exit number. Checking the route and exit numbers before journey reduces the risk of finding the way when drive. Keep to the nearside lane of an expressway unless overtaking, and overtake only at the offside of the other vehicle. When driving on the nearside lane, there may be other drivers trying to merge in from the slip road and sometimes it is difficult to find a safe space, change to the center lane or adjust speed to let others merge in with enough safety margins. Medium goods vehicles, heavy goods vehicles and buses are prohibited from using the offside lane of an expressway where the carriageway has three or more traffic lanes available. When leaving an expressway, use the speedometer to check if the speed is within legal limit. Do not rely on intuition. After staying on the expressway for a while, the actual speed traveling is usually "higher" than that estimated by the driver thus affecting driving safety.
