Get a replacement before drivingThis was the right answer

Don't drive without a fuel filler cap in place, as fuel could spill onto the road, especially when you're cornering or turning at a roundabout. Diesel fuel will make the road surface extremely slippery. Any spillage should be reported, so that the emergency services can make the road safe.
