Clause 5.1 requires the plot to accommodate fuel pumps, offices, storage, compressor and air pump rooms, and kiosks without obstructing vehicle flow, especially during peak hours. Layout should prevent vehicles from encroaching on access roads and position kiosks to avoid traffic interference.
These dimensions ensure safe and efficient fuel station operation along highways.
References: Clause 5.2, Clause 5.1
Per IRC 12, access roads must incorporate deceleration and acceleration lanes to enable safe ingress and egress for fuel stations (Clause 6.1.1). Stations situated on highways with service roads must have access exclusively through those service roads. For clusters of fuel stations, a shared access via a 7.0 m wide service road linked with acceleration and deceleration lanes is recommended (Clause 4.6.3). Drainage provisions require that the station and access area be at least 300 mm below the highway shoulder to prevent drainage onto the highway, with slab culverts fitted with iron gratings managing stormwater (Clause 6.2). Layouts must respect building lines and rights of way to accommodate future highway expansion (Clause 8).
References: Clause 6.1.1, Clause 4.6.3, Clause 6.2, Clause 8
According to IRC 12 Clause 4.5, fuel stations must be located at least 1000 meters away from intersections, including median gaps treated as intersections, on National Highways, State Highways, and Major District Roads. For Rural Roads in plain and rolling terrains, this distance may be reduced to 300 meters based on traffic volumes. Clause 4.7 further mandates that stations be no closer than 1000 meters to toll plazas and railway crossings, except when toll barriers are situated on service roads separated from main highways. Additionally, stations should maintain a minimum distance of 200 meters from the start of Road Over Bridge (ROB) approach roads and 500 meters from grade separators or ramps. All distances are measured along the centerline of the nearest carriageway between tangent points of curves at intersections or median openings and the station access or egress points.

IRC 12 addresses drainage primarily in Clause 6.2 and related sections. It requires that the fuel station and access areas be positioned at least 300 mm below the highway shoulder level to prevent runoff onto the road or waterlogging. Surface water must be collected using underground drainage systems and discharged into natural watercourses via slab culverts fitted with iron gratings capable of handling expected loads; use of pipe culverts is prohibited. Drainage systems must prevent water accumulation and surface flow onto highways, with detailed drainage designs submitted for approval. Entry and exit points must have slab culverts with gratings to manage stormwater discharge, as referenced in Clause 35.00. These measures ensure effective water management and prevent contamination or flooding of highway surfaces.
References: Clause 6.2, Clause 35.00
IRC 12 Clause 9.1 mandates an adequate system of signs and pavement markings for guiding highway users to fuel stations. Pavement markings include chevron patterns at entry and exit points and 'Give Way' markings at exits. Informative signs indicating fuel station presence must be placed at 1 km and 500 m in advance, as well as at the entry point. Clause 6.2 refers to typical layouts showing signs and markings for stations in various terrains, such as urban and hilly areas (Figure 5). These standards ensure visibility and safe access across all road types and terrains, also considering drainage and right-of-way clearance requirements (Clauses 3.2, 6.2, 8). The system promotes consistent, clear, and safe communication for highway users approaching fuel stations.
