Notes: For the latest list of expressways, see ʻFurther Reference Materialsʼ.

Trunk roads are busy roads which link up areas and districts. Some trunk roads are designated as expressways.

All expressways and most of the trunk roads are high standard multi-lane dual carriageways with grade-separated interchanges and are designed to carry a high volume of traffic at a higher speed.

The following roads are presently designated as expressways:

A. Sha Tin Road
B. Sha Lek Highway and Tateʼs Cairn Highway (Sha Tin Road to Ma On Shan Road)
C. Tai Po Road - Sha Tin (Tolo Highway to Wo Che Estate)

Under the Road Traffic (Expressway) Regulations, there are special driving rules to enhance road safety and maintain smooth traffic flow on expressways:

  • Keep to the left most lane of an expressway unless you are heading for a right side exit or overtaking another vehicle, and overtake only on the right.
  • Medium goods vehicles, heavy goods vehicles and buses are prohibited from using the right most lane of an expressway where the carriageway has three or more traffic lanes available unless they are heading for a right side exit. Moreover, if you ride a motor cycle or motor tricycle, or drive a private car or light goods vehicle on an expressway while holding a probationary driving licence for the corresponding vehicle class, the same restriction applies to you.
  • You must not drive on the hard shoulder, verge or central reservation of an expressway except during traffic diversion, breakdown or emergency. The boundary of the hard shoulder, verge or central reservation is normally indicated by a thick solid white line.
  • You must not U-turn or reverse your vehicle on an expressway.
  • You must not stop or park your vehicle on any part of an expressway except for breakdown or emergency, and in these situations, you must turn on the hazard warning lights, and if possible drive off the carriageway and stop on the verge or hard shoulder.
  • Cyclists and pedestrians are prohibited from using expressways. Wire fences are erected along the boundaries of expressway areas.
  • Vehicles driven by learner drivers, public light buses, special purpose vehicles and any vehicle with an engine of cylinder capacity under 125cc (or if the vehicles are solely propelled by an electric motor - electric private car with a rated power less than 7 kilowatts, and electric motor cycle or motor tricycle with a rated power less than 3 kilowatts) are not allowed to use an expressway, unless prior written permission has been obtained from the Commissioner for Transport.

The rules/advice below are also generally applicable to expressways and trunk roads:

  • Vehicles tend to travel faster on expressways and trunk roads. The faster speeds on expressways and trunk roads mean that you need more time for many driving actions. You need more time to slow down and stop. You need more time to change direction. You should signal other road users your intention as early as possible. As with driving on any road, you need to be fit and alert. You need to give yourself bigger margins than on ordinary roads, such as more space between your vehicle and the one in front.
  • When driving on expressways and trunk roads, your speed may be higher than you think. You may not only underestimate the stopping distance for your actual speed but also easily exceed the speed limit. Although you may feel safe, you must not exceed the speed limit for the road, or for your vehicle. There may be hidden dangers.
  • Higher noise levels, particularly in wet weather, may prevent other drivers from hearing your horn. Flashing your headlamps is usually a better warning of your presence when necessary. Be alert for such a warning yourself.
  • Change lanes only when there is a need and it is safe to do so. Keep in the middle of the lane you are using and do not let your vehicle wander from side to side or into other lane.

In this chapter, you will find rules and advice that will help you drive safely on expressways and trunk roads.

Some of the more important points are:

  • Making sure you are in good shape and your vehicle in good working condition - pages 41 and 42.
  • Looking well ahead to give yourself more time to react - page 69.
  • Using headlamps if visibility is reduced - page 87.
  • Maintaining a safe gap - page 55.
  • Lane discipline and overtaking - pages 56 and 68.
  • Joining and leaving a dual carriageway or an expressway at intersections - pages 82 and 83.
  • Breakdowns and emergencies - pages 133 and 134.
  • Keeping left unless overtaking - page 71.
  • Overtaking only on the right - page 68.

Trunk roads and expressways designated as strategic routes are assigned with route numbers and the exits along each route are also assigned with exit numbers. These route and exit numbers are shown on direction signs to assist you in finding your way. A full description of the route numbering system for strategic routes is provided on pages 128 and 129.
