What Is This Legislation About?
The Road Traffic (Expressway Traffic) Rules (“Expressway Traffic Rules”) set out a specialised traffic regime for Singapore’s expressways and road tunnels. In plain terms, they regulate how vehicles (and, in limited respects, people) may move on these high-speed, controlled-access roads. The rules are designed to reduce the risk of collisions and secondary incidents by limiting where vehicles may travel, stop, or remain at rest.
Unlike ordinary roads, expressways are engineered for continuous traffic flow and are typically separated by central dividers, shoulders, and verges. The Rules therefore impose stricter behavioural requirements—particularly around stopping, reversing, and use of shoulders and verges. They also address conduct in tunnels, where visibility, evacuation, and emergency response considerations differ from open road conditions.
Scope-wise, the Rules apply to “any expressway” and “any road tunnel”. The definition of “expressway” includes parts of an expressway that are expressway tunnels, while “road tunnel” refers to tunnels specified in the Second Schedule. This means the Rules operate as a unified framework for both open expressway carriageways and tunnel segments.
What Are the Key Provisions?
1. Definitions and interpretive approach (Rule 2)
Rule 2 provides definitions that matter for enforcement and interpretation. For example, “carriageway” is defined as the part of an expressway with a suitable surface for regular vehicular passage, distinguishable from shoulders/verges and excluding the central divider and shoulder. “Shoulder” and “verge” are also defined in functional terms. “Expressway tunnel” and “road tunnel” are defined by reference to the Second Schedule, which is critical because the Rules’ tunnel-specific prohibitions apply only to tunnels designated in that schedule.
Rule 2(2) contains an important interpretive clause: where a provision contains a prohibition or restriction relating to driving, moving, stopping, or remaining at rest, it is construed as prohibiting the use of the expressway by driving/moving/stopping (or causing or permitting such conduct) in contravention of that restriction. This matters for liability not only for the driver, but also for persons who “cause or permit” a vehicle to be driven or remain in contravention.
2. Application of the Rules (Rule 3)
Rule 3 states that the Rules apply to (a) any expressway and (b) any road tunnel. This is the foundation for the entire regulatory scheme. Practitioners should note that the Rules’ restrictions are not limited to certain named expressways; they apply broadly to all expressways and designated road tunnels.
3. Where vehicles may drive (Rules 4 and 5)
Rule 4 prohibits driving on any part of an expressway that is not a carriageway. This is a strong spatial restriction: it prevents vehicles from using shoulders/verges/other non-carriageway areas as driving lanes. Rule 5 then requires that every vehicle on a carriageway be driven so that the central divider is at all times on the right or off-side of the vehicle. This effectively codifies the correct lane/side orientation for traffic flow relative to the central divider.
4. Stopping and remaining at rest (Rule 6)
Rule 6 is one of the most practically important provisions. The general rule is that no vehicle shall stop or remain at rest on a carriageway. However, Rule 6(2) creates limited exceptions where stopping is necessary due to: (a) breakdown/mechanical defect or lack of fuel/oil/water; (b) illness, accident, or emergency; (c) to recover/remove an object fallen on the expressway; or (d) to allow help to be given to another person in those circumstances.
Where an exception applies, the vehicle must, as soon as practicable, be driven or moved off the carriageway to the shoulder or verge on the left or near side of the vehicle. Rule 6(3) further requires that, while at rest on the shoulder/verge, the vehicle should (as far as reasonably practicable) remain positioned so that no part of the vehicle or load obstructs or causes danger to other vehicles, and should not remain longer than necessary in the circumstances. Rule 6(4) preserves stopping where prevented by other vehicles/persons/objects or where stopping is permitted by traffic signs or police direction.
5. Reversing, shoulder/verge use, and central divider prohibitions (Rules 7–9)
Rule 7 prohibits driving or moving backwards on a carriageway except to the extent necessary to proceed forward or to connect to another vehicle. This is aimed at preventing dangerous manoeuvres on high-speed carriageways.
Rule 8 prohibits driving, moving, stopping, or allowing a vehicle to remain at rest on any shoulder or verge except in accordance with Rule 6(2) and (3). In other words, shoulders/verges are not general-purpose spaces; they are emergency/incident spaces. Rule 9 prohibits any vehicle from being driven, moved, stopped, or allowed to remain at rest on the central divider. This is consistent with the central divider’s role as a physical separation and safety barrier.
6. Provisional licence restrictions (Rule 10)
Rule 10(1) provides that no holder of a provisional driving licence granted under section 36(3) of the Road Traffic Act may drive a motor vehicle on an expressway. This is a safety measure reflecting the higher complexity and risk of expressway driving.
Rule 10(2) creates an exception for holders of a Class 2B provisional licence attending a training programme known as the “Expressway Familiarisation Ride” under the Road Traffic (Motor Vehicles, Driving Licences) Rules. The exception is time-bounded (between 9.30 a.m. and 4 p.m. on any day except public holidays). For practitioners, this is a key compliance point: the exception is not general “training” permission; it is tied to a specific programme and specific hours.
7. Tunnel-related conduct and vehicle prohibitions (Rules 13–14)
The extract indicates that Rule 13 addresses “general restrictions in relation to conduct in road tunnels and expressway tunnels”, while Rule 14 addresses “general prohibitions in relation to vehicles allowed in road tunnels and expressway tunnels”. Although the provided text is truncated, the structure signals that the Rules treat tunnels as distinct environments with additional behavioural and vehicle-type restrictions. In practice, tunnel rules often cover matters such as conduct during incidents, stopping/parking, and restrictions on certain vehicle categories depending on tunnel safety requirements.
8. Prohibition on being on expressway on foot or skates (Rule 14A)
Rule 14A provides a specific prohibition: no person may, at any time while on foot, go or remain on any part of an expressway not being (as indicated in the extract) a specified part. This is a targeted safety rule addressing pedestrian access to expressways, which are generally designed for vehicular traffic only. The “not being” language implies that there is a limited permitted area (likely designated for pedestrians in exceptional circumstances, such as authorised access points or emergency egress routes), but the general rule is exclusion.
9. Exceptions (Rule 15)
Rule 15 states that the Rules shall not apply to certain circumstances or persons. The extract indicates “These Rules shall not apply to —” but does not show the list. In many traffic rule instruments, such exceptions cover authorised vehicles (e.g., police or emergency services) or situations where compliance is impracticable due to official duties. Practitioners should consult the full text of Rule 15 to identify the precise carve-outs.
How Is This Legislation Structured?
The Expressway Traffic Rules are structured as a short, rules-based instrument with a citation provision and a set of operative rules. Based on the provided table of contents, the Rules include:
Rule 1 (Citation); Rule 2 (Definitions and interpretive guidance); Rule 3 (Application to expressways and road tunnels); Rules 4–12 (core driving and vehicle-use restrictions, including carriageway use, direction of driving, stopping, reversing, shoulder/verge use, central divider prohibition, and provisional licence restrictions); Rules 13–14A (tunnel conduct and vehicle prohibitions, plus the pedestrian-on-expressway prohibition); and Rule 15 (Exceptions).
The instrument also contains schedules: the First Schedule (repealed), Second Schedule (likely listing expressways and tunnels by reference), and Third Schedule (interpretation of abbreviations used in the Third Schedule). The legislative history and amendment timeline indicate frequent updates, reflecting evolving safety and operational needs.
Who Does This Legislation Apply To?
The Rules apply primarily to drivers and vehicle users on expressways and road tunnels. Because Rule 2(2) extends prohibitions to persons who “cause or permit” contraventions, liability can extend beyond the person physically driving the vehicle, depending on the facts (e.g., a person who arranges or authorises a vehicle’s use in contravention of the Rules).
They also apply to pedestrians through Rule 14A, which restricts going or remaining on parts of an expressway on foot. Additionally, the Rules apply to vehicle categories where tunnel-specific prohibitions or speed-limit-related rules apply (not fully reproduced in the extract, but indicated by the presence of Rule 12 and the tunnel rules). Finally, the provisional licence restriction in Rule 10 targets a specific class of learner drivers and training contexts.
Why Is This Legislation Important?
Practically, these Rules are central to expressway safety enforcement. The expressway environment is unforgiving: stopping on the carriageway can create high-speed collision risks, and improper use of shoulders/verges can block emergency access or create hazards. The Rules’ strict spatial restrictions (carriageway-only driving; central divider prohibition; shoulder/verge limited to incident circumstances) provide clear, enforceable standards.
For practitioners—whether advising drivers, fleet operators, or responding to incidents—the Rules’ structure offers a roadmap for assessing liability. Key questions typically include: Was the vehicle stopped on the carriageway? If so, did a Rule 6(2) exception apply, and was the vehicle moved to the shoulder/verge as soon as practicable? Was the vehicle positioned to avoid obstruction or danger, and did it remain only as long as necessary? Was the driver a provisional licence holder, and did a specific training exception apply?
From an enforcement and compliance perspective, the Rules also support operational consistency across different expressways and tunnels by tying applicability to scheduled road/tunnel designations. Amendments over time (including the 2024 and 2022 amendments shown in the timeline) indicate that the regulatory framework is actively maintained to address emerging safety and operational considerations.
