A forecourt is marked like any busy car park, with one-way arrows, lane hatching, give way lines and bays, but the work has to fit around fuel. That means agreeing a permit to work with the operator, choosing materials that suit the hazardous areas around pumps and vents, and keeping the station trading while the lines go down.
Last reviewed: November 2026. Every forecourt operator has its own safety rules, and the site's permit to work and petroleum storage arrangements always take precedence over anything a contractor proposes. What follows is how the marking side of the job is usually planned, so that you know what to expect and what to ask before work is booked.
What markings does a forecourt need?
The layout depends on the size of the site and how traffic reaches the pumps, but most forecourts rely on the same set of markings to keep vehicles moving in one direction and away from the areas that matter most.
- Entry and exit arrows, no entry markings and one-way flow through the pump lanes, so drivers approach the pumps from the correct side and leave without crossing oncoming traffic.
- Hatching around pump islands, canopy columns and other fixed obstructions, to keep vehicles from clipping them.
- Give way and stop lines at the exit onto the public road, and anywhere forecourt traffic meets the shop car park.
- A clearly marked tanker stand and keep clear areas around the fill points and vent pipes, so the delivery tanker can park, offload and leave without obstruction.
- Pedestrian routes between the pumps, the shop and any parking, with a crossing point where people have to cross a traffic lane.
- Parking bays for the shop, including accessible bays close to the entrance, and separate bays or queuing lanes for air and water, the car wash, click and collect and EV chargers where the site has them.
Markings on the forecourt itself are not normally governed by the regulations for public highways, but following the same shapes and colours drivers see on the road makes the layout easier to read at a glance. We have covered how that works on private sites in more detail in are line markings needed on private roads.
Why is marking a forecourt different from marking a car park?
The difference is the fuel. Petrol filling stations store and dispense flammable liquids, so they are regulated through petroleum licensing and the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR), and the areas around dispensers, vent pipes and tanker fill points are classified as hazardous areas where flammable vapour may be present. Anything that could act as an ignition source in those areas, including some of the equipment used for line marking, is controlled by the operator.
In practice this means three things for the marking work. The job is carried out under the operator's permit to work, and the permit will set out which areas can be worked on, at what time, and with what equipment. Some areas may need pumps to be taken out of use while the work is done nearby. And the choice of marking material is shaped as much by the hazardous areas as by the traffic.
Which materials can be used near the pumps?
Hot-applied thermoplastic is the hard-wearing choice for most external markings, but it is heated to around 200°C and applied with gas-fired equipment, which is exactly the kind of ignition source a forecourt permit is designed to control. For that reason, cold-applied materials such as MMA or specialist road marking paints are often specified within and close to the hazardous areas, with thermoplastic used further out on the approach roads, exits and shop car park where the permit allows it.
There is no single right answer for every site. Thermoplastic generally lasts longer under heavy traffic, cold-applied materials avoid heat and flame altogether, and the right mix depends on where each marking sits, how hard it is driven over and what the operator's safety rules allow. We will always explain the trade-offs before you commit, and the material choice should be agreed as part of the permit, not decided on the day. We have compared the two main options in what's the difference between thermoplastic and MMA line marking.
Does fuel damage the surface and the markings?
It can. Petrol and diesel soften the bitumen that binds tarmac together, which is why pump islands and the areas directly in front of them are usually laid in concrete rather than asphalt. Markings on a forecourt are therefore often split across two surfaces, with concrete pads around the pumps and tarmac on the approach and exit, and each needs its own preparation and, in some cases, its own material.
Fuel spills, oil drips and tyre rubber also leave a film on the surface that stops new markings bonding properly. A marking applied over a contaminated surface may look fine on the day and then lift within months, so cleaning and degreasing the areas to be marked is part of the job rather than an extra. We have explained how commercial cleaning is carried out, including how washwater is contained on sites with drainage interceptors, in what does commercial jet washing involve.
How slippery should a forecourt be allowed to get?
A forecourt combines spilled fuel, rain and constant foot traffic between the pumps and the shop, so slip resistance matters more here than on most car parks. Pedestrian walkways, crossing points and the areas around pump islands can be finished with an anti-slip coating or a marking that carries anti-slip aggregate, giving people better grip in the places they are most likely to be walking on a wet or contaminated surface.
Where a site has had slips, or wants evidence that the surface is suitable, slip resistance can be measured using the pendulum test, which gives a Pendulum Test Value (PTV) that can be compared with published guidance and rechecked over time.
Can a forecourt stay open while it is marked?
Usually, yes, at least in part. Most forecourts are marked in phases, working on one group of pump lanes or one area at a time while the rest of the site keeps trading, with the working area coned off and customers directed to the open pumps. On sites that trade around the clock, the busiest areas are often programmed for the quietest hours, including overnight where the operator prefers it.
What determines the programme is the permit, the number of pumps that can be closed at once, and the cure time of the materials being used. Cure times depend on the product, the temperature and the weather, so a sensible programme allows for each area to cure before it is reopened to traffic. We have covered the general approach in how do you line mark a live car park without closing it.
What changes when EV chargers or a new layout are added?
Many forecourts are adding EV chargers, rearranging parking or changing how vehicles queue for the car wash or click and collect, and every one of those changes leaves the old markings in the wrong place. Old lines that are simply painted over tend to show through as ghost lines, which confuse drivers on a site where clear direction matters, so the old layout should be properly removed before the new one is marked out.
That is also a good moment to look at the whole forecourt rather than one corner of it. A survey of the existing markings, the surface condition and the traffic flow helps make sure the new layout works with the rest of the site, and that tired markings elsewhere are refreshed at the same time rather than on a separate visit.
How C&R can help.
C&R cleans, prepares and marks forecourts and the car parks around them nationwide, with one team handling degreasing and jet washing, removal of old markings, new line marking and anti-slip coatings. We work to the operator's permit to work and site rules, choose materials to suit the hazardous areas and the traffic, and phase the work so the station can keep trading, including overnight where the site demands it. We are CHAS and SafeContractor accredited and hold ISO 9001, ISO 14001 and ISO 45001, and every job comes with before and after photographs.
Frequently asked questions.
Can a petrol station stay open while it is line marked?
Usually, yes. Most forecourts are marked in phases, one group of pump lanes at a time, while the rest of the site keeps trading. Busy areas are often done overnight.
Can thermoplastic be used on a forecourt?
Often, but not everywhere. Thermoplastic is applied hot with gas-fired equipment, so cold-applied materials such as MMA are often used near pumps, vents and fill points, as the operator's permit allows.
Why do markings peel off forecourts?
Usually because fuel, oil and tyre rubber on the surface stopped the marking bonding. Cleaning and degreasing before marking is essential.
What markings does a tanker delivery area need?
A clearly marked tanker stand and keep clear areas around the fill points and vent pipes, so the tanker can park, offload and leave without obstruction.
Do forecourt markings have to follow highway regulations?
Not normally, as a forecourt is private land, but using the shapes and colours drivers know from the road makes the layout far easier to follow.
