A vehicular crossing application in Singapore is handled through the Land Transport Authority (LTA). It is required when a development proposes a new vehicular access point, or relocates or widens an existing one, between private land and a public road. The Qualified Person (QP) submits the proposal, usually the QP (Civil), and LTA clearance must be in hand before the access is built. This article sets out when clearance applies, what the submission contains, which design rules govern the crossing, and how the stages run.
TL;DR
- A new, relocated or widened access point on a public road needs LTA clearance, obtained by the QP, unless the development falls under the exemptions in Appendix 1B of the Code of Practice for Works on Public Streets.
- The submission shows access location, clear width, gradient, turning kerb radius, configuration and a swept path for the largest vehicle expected.
- Sight lines matter most: a minimum 12 m stopping sight distance and splayed or porous boundaries at the access.
- Permits for physical works on public streets are a separate application, filed electronically through LTA.PROMPT.
- Resolving access location, sight lines and levels at the design stage avoids redesign at later gateways.

What a vehicular crossing application covers
A vehicular crossing is the point where vehicles move between a property and the public road network. In LTA’s terminology the matter is treated as an access point within street works proposals relating to development works. The QP must obtain LTA clearance for development proposals involving new access points or the relocation or widening of existing access points.
The assessment is about the road, not only the plot. LTA evaluates whether vehicular access points are suitably located to keep traffic flowing smoothly. A driveway that suits the architect’s layout may still be refused or moved if it sits too close to a junction or conflicts with a bus stop.
The application applies to a wide range of projects:
- Landed homes adding or widening a driveway (see our note on LTA submissions for driveway modifications on landed homes).
- Commercial and industrial redevelopments with new loading or service entrances.
- Warehouses, schools and mixed-use sites where the access serves heavy or high-volume traffic.
Who applies, and at which stage
The applicant in practice is the QP appointed for the project. The QP (Civil) must ensure that engineering works adjacent to or within public streets are appropriately designed, supervised and executed. The owner or developer funds and instructs the work, but the QP carries the professional responsibility for the submission.
Clearance is required at the Layout Plan, Street Plan and CSC stages. At the Building Plan stage, the QP (Civil) submits only Street Plans to LTA, and Building Layout Plans are not required.
Exemptions
Some developments are exempt from LTA clearance if they meet the criteria listed in Appendix 1B of the Code of Practice for Works on Public Streets, as set out on LTA’s development and construction specifications page. Whether a project qualifies is a technical judgment against the appendix text. It should not be assumed from the size of the works.
What the submission must contain
LTA’s published requirements for street works proposals relating to development works describe the technical content. Submissions include site and supplemental plans, together with access location, clear width, gradient, turning kerb radius and configuration, and a swept path for the largest vehicle envisioned.
| Item | Why LTA reviews it |
|---|---|
| Site plan and supplemental plans | Shows the access in the context of the road and neighboring accesses |
| Access location | Tests safe distance from junctions, bends and crossings |
| Clear width and configuration | Confirms vehicles can enter and leave without encroaching |
| Gradient | Checks the transition from road level to the property |
| Turning kerb radius | Governs how the largest vehicle turns in and out |
| Swept path | Demonstrates the largest expected vehicle can maneuver |
The swept path is where many drawings fail. It must reflect the largest vehicle that the development will realistically receive, not the typical one. A residential driveway is checked against a car, whereas a logistics unit needs a swept path for a goods vehicle.
Design and road-safety requirements
Where the access may sit
LTA’s Code of Practice for Road Transit Systems states that access points should be located at a safe distance from road junctions, bends, pedestrian crossings, bus stops and existing access points. Where more than one road category fronts a site, access points should be along the lowest hierarchy of roads. For a corner plot, this usually means taking the access from the minor road.
Sight lines and boundaries
Vehicles leaving a property meet pedestrians, cyclists and other active mobility users at low height and high speed difference. LTA’s Active Mobility Design Guide asks for splayed or porous boundaries at vehicular accesses, no hard structures or tall, dense vegetation in the sight-line area, and a minimum 12 m stopping sight distance to be shown on the drawings.
In practice, this affects fence design, gate posts, planters and pillars next to the driveway. A solid boundary wall that is acceptable elsewhere along the frontage may need to be splayed or replaced with a porous treatment at the crossing.
Separating users
LTA’s quick guide for development proposals advises that separating vehicles, cyclists and pedestrians through dedicated infrastructure is a primary way to reduce conflict. Where a crossing cuts across a footpath or cycling path, the layout should keep the conflict zone short and visible.
Standards the QP must apply
QPs are responsible for ensuring that proposals involving vehicular access comply with the latest LTA standards, including the Civil Design Criteria for Road & Rail Transit Systems and the LTA Standard Details of Road Elements (SDRE), as stated in LTA’s street works submission requirements. Our guide to LTA civil works specifications for QPs explains where each standard sits and which version to cite.
The approval stages
LTA requires street works submissions at three gateways: Design, Construction and Completion, according to its development and construction resources page. The vehicular crossing is normally resolved in the earliest of these, then carried through.
- Design Gateway (DG). The access location, width, gradient and swept path are submitted with QP endorsement. Most comments arise here.
- Construction Gateway (CG). Detailed plans are submitted, including structural, interfacing, connection and foundation details. This also requires QP endorsement.
- Completion Gateway. The built works are presented for completion checks before the street works are closed out.
A change to the crossing after DG, such as moving a gate for a late layout revision, can reopen the review. It is cheaper to settle the access early than to redraw at CG.
The works permit is a separate step
Clearance for the design does not authorize digging up the road verge or kerb. Permit applications for works affecting public streets are submitted electronically through LTA.PROMPT and include location and site plans, a pre-condition photographic survey report and a method statement. Where applicable, a Public Liability Policy of at least S$1 million is also required, per the June 2023 edition of the Code of Practice for Works on Public Streets.
For the permit track, see our checklists on the road opening permit and the street works permit for lane occupation.
Fees and timing
LTA publishes a Service Standard & Fees Schedule that states the fees and service standards for its submissions, linked from its development and construction resources page. Fees and processing targets are revised from time to time, so the current schedule should be read before budgeting. Actual elapsed time depends mainly on how many comment rounds the submission goes through, which is why completeness at first submission matters more than any single target.
Common reasons a crossing is queried
- Access placed near a junction, bend, bus stop or pedestrian crossing.
- Access taken from a higher-category road when a lower one fronts the site.
- Swept path drawn for a vehicle smaller than the one the use requires.
- Hard boundary structures or planting inside the sight-line area.
- Gradients that are not reconciled between the road level, the footpath and the platform level.
- Drawings that do not cite the current SDRE and design criteria.
Our perspective
Most delays on vehicular crossings do not come from LTA’s process. They come from access decisions made as architectural afterthoughts. When the building layout is fixed first and the driveway is fitted in last, the sight lines, levels and kerb geometry rarely work, and the QP has to reopen the design.
We treat the crossing as a civil design question from the first sketch. That means checking road hierarchy and neighboring accesses before the layout is frozen, drawing the swept path for the real design vehicle, and testing the boundary against the 12 m sight-distance requirement. Where a project also needs BCA, URA or other authority submissions, we coordinate them so the access geometry is the same on every set of drawings. Our wider approach is set out in our guide to key steps for LTA approval.

How AEC Technical supports the submission
We prepare and manage statutory authority submissions in Singapore, including the PE and QP endorsements that LTA street works proposals depend on, together with the civil, structural and architectural design behind them. A vehicular crossing is usually one part of a wider package, so it is handled alongside building plan, URA and BCA work rather than in isolation.
To discuss a project, see our PE endorsement and authority submission services or the full list of services. The wider regulatory background is in our LTA regulations guide for Singapore construction.
A practical sequence for owners and developers
- Confirm the road category and the location of junctions, bus stops, crossings and neighboring accesses along the frontage.
- Check whether the proposal falls under an Appendix 1B exemption. If it does not, plan for LTA clearance.
- Appoint the QP and settle the design vehicle for the swept path.
- Prepare site and supplemental plans showing width, gradient, kerb radius and sight-line area.
- Submit at the correct plan stage and respond to comments with revised drawings that cite current LTA standards.
- Apply for the works permit through LTA.PROMPT before any work affects the public street.
- Complete the works to the endorsed design and present them at the Completion Gateway.
FAQ
Who submits a vehicular crossing application in Singapore?
The appointed QP submits it to LTA, normally the QP (Civil). The owner or developer instructs and pays for the work, but the QP is responsible for the design, supervision and compliance of the works at the public street interface.
Is LTA clearance always required for a driveway change?
Clearance is required for new access points and for relocating or widening existing ones, unless the development meets the exemption criteria in Appendix 1B of the Code of Practice for Works on Public Streets. The QP should check the appendix against the actual proposal before deciding.
What drawings does LTA expect for the crossing?
Site and supplemental plans showing the access location, clear width, gradient, turning kerb radius and configuration, plus a swept path for the largest vehicle envisioned. The sight-line area and the 12 m stopping sight distance should also be shown where active mobility users are present.
Does approval of the crossing cover the works on the road?
No. Physical works affecting a public street need a separate permit through LTA.PROMPT, with a method statement, a pre-condition survey and, where applicable, public liability insurance of at least S$1 million.
